The ____________ energy is the total amount of energy contained in an object.
Explanation
The internal energy refers to the total amount of energy that is present within an object. This includes all forms of energy such as kinetic energy, potential energy, and thermal energy. It represents the sum of all the microscopic energy particles within the object, including the motion and interactions of its atoms and molecules. The internal energy is a fundamental concept in thermodynamics and is used to study and analyze various physical systems.Rate this question:
- 2.
Internal energy is
- A.
The amount of heat required to change the temperature of something 1 degree C
- B.
The energy transferred between objects because of a temperature difference
- C.
The total of all energies in a substance
- D.
None of the above
Correct Answer
C. The total of all energies in a substanceExplanation
Internal energy refers to the total energy possessed by a substance, including both its kinetic and potential energies. It encompasses all forms of energy present within the substance, such as the energy associated with the motion of its particles, the potential energy stored in chemical bonds, and the energy due to its temperature. It is not solely limited to the amount of heat required to change the temperature of the substance by 1 degree Celsius or the energy transferred between objects due to a temperature difference.Rate this question:

The specific heat capacity is the amount of heat required to change the temperature of a unit mass of a substance by 1 degree C.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement correctly defines specific heat capacity as the amount of heat needed to raise the temperature of a given mass of a substance by 1 degree Celsius. Therefore, the answer "True" is correct.Rate this question:

Heat is the energy transferred between objects because of a ___________________.
Correct Answer
temperature differenceExplanation
Heat is the energy transferred between objects because of a temperature difference. When two objects have different temperatures, heat flows from the object with higher temperature to the object with lower temperature until they reach thermal equilibrium. This transfer of energy is what we perceive as heat. The greater the temperature difference between the objects, the greater the amount of heat transferred.Rate this question:
- 5.
Heat is measured in
- A.
Joules
- B.
Kilograms
- C.
Calories
- D.
Both A and C
Correct Answer
D. Both A and CExplanation
Heat is a form of energy and can be measured in different units. Joules and calories are both commonly used units to measure heat. Therefore, the correct answer is A and C, as both joules and calories are valid units for measuring heat.Rate this question:

- 6.
In general, objects contract when heated because molecules move more.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
When heated, molecules gain energy and move more, causing them to spread out and increase in volume. This expansion is the reason why substances generally expand when heated, rather than contract. Therefore, the statement that "things contract when heated because molecules move more" is incorrect.Rate this question:
-
- 7.
Heat flows from hot to cold
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Heat flows from hot to cold due to the principle of the second law of thermodynamics. According to this law, heat naturally moves from a region of higher temperature to a region of lower temperature until both regions reach thermal equilibrium. This process occurs because the molecules in a hotter substance have more kinetic energy and collide with the molecules in a colder substance, transferring energy and increasing their temperature. Therefore, heat transfer always occurs in the direction of hot to cold.Rate this question:

Liquids expand when heated except
- A.
Alcohol
- B.
Water
- C.
Oil
- D.
Juice
Correct Answer
B. WaterExplanation
Liquids generally expand when heated due to the increased kinetic energy of their particles. However, water is an exception to this rule. As water is heated, it undergoes a unique phase change known as the "anomalous expansion of water." When water is heated from 0°C to 4°C, it actually contracts and becomes denser. This is because the hydrogen bonding between water molecules becomes more ordered, causing the water to take up less space. However, once the temperature exceeds 4°C, water starts to expand like other liquids.Rate this question:

- 9.
Heat transfer needs thermal contact
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Heat transfer occurs when there is a temperature difference between two objects or substances. In order for heat to transfer, there needs to be thermal contact between the objects or substances involved. This means that they must be in direct physical contact or connected by a medium that allows the transfer of heat, such as a solid, liquid, or gas. Without thermal contact, heat cannot be transferred from one object to another. Therefore, the statement "heat transfer needs thermal contact" is true.Rate this question:

Which temperature(s) does absolute zero exist at?
- A.
72 Fahrenheit
- B.
-459 Fahrenheit
- C.
-252 celsius
- D.
0 kelvin
- E.
-273 kelvin
- F.
-273 celsius
Correct Answer(s)
B. -459 Fahrenheit
D. 0 kelvin
F. -273 celsiusExplanation
The given answer includes three values that represent absolute zeros on different temperature scales. -459 Fahrenheit is the absolute zero on the Fahrenheit scale, 0 kelvin is the absolute zero on the Kelvin scale, and -273 Celsius is the absolute zero on the Celsius scale. These values represent the lowest possible temperature that can be reached, where molecular motion ceases.Rate this question:

Calorimeters find the internal energy of something
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Calorimeters are devices used to measure the heat transfer in a system, not the internal energy. Internal energy refers to the sum of the kinetic and potential energies of the particles within a substance, while calorimeters measure the heat gained or lost during a chemical or physical process. Therefore, the statement that calorimeters find the internal energy of something is incorrect.Rate this question:

________ is when two objects have the same temperature
Correct Answer
thermal equilibriumExplanation
Thermal equilibrium refers to the state in which two objects are at the same temperature. In this state, there is no net flow of heat between the objects, as they have reached a balance in their thermal energies. This occurs when the rate of heat transfer from one object to another is equal to the rate of heat transfer in the opposite direction.Rate this question:
- 13.
Thermal __________ needs to be in contact
Correct Answer
equilibriumExplanation
Thermal equilibrium refers to a state where two or more objects or systems are in contact and have the same temperature. In this state, there is no net transfer of heat between the objects, as they are in balance. Therefore, for thermal equilibrium to occur, objects need to be in contact with each other.Rate this question:
- 14.
Thermal Equilibrium has no transfer of energy.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
In thermal equilibrium, there is no transfer of energy because the temperatures of the objects or systems in contact with each other are equal. This means that there is no temperature difference driving the transfer of heat from one object to another. Therefore, no energy is transferred between the objects, resulting in a state of thermal equilibrium.Rate this question:
-

Temperature is
- A.
The heat transferred from one thing to another
- B.
How hot or cold something is
- C.
Related to the average molecular kinetic energy in a substance
- D.
Found by two objects in thermal equilibrium
- E.
When particles stop moving
- F.
The measure of kinetic energy of a particle
- G.
Measured in fahrenheit, celsius and kelvin
- H.
Measured in calories and joules
Correct Answer(s)
B. How hot or cold something is
C. Related to the average molecular kinetic energy in a substance
F. The measure of kinetic energy of a particle
G. Measured in fahrenheit, celsius and kelvinExplanation
Temperature is a measure of how hot or cold something is. It is also related to the average molecular kinetic energy in a substance, as the temperature increases, the average kinetic energy of the molecules increases. Therefore, temperature can be considered as a measure of the kinetic energy of a particle. Temperature can be measured in different units such as Fahrenheit, Celsius, and Kelvin, which are commonly used to quantify temperature.Rate this question:
