Which of the following temperature scales has an absolute zero point, where all molecular motion theoretically ceases?
Correct Answer
C. Kelvin
Explanation
The Kelvin scale is an absolute temperature scale where zero Kelvin (0 K) represents absolute zero, the theoretical point at which all molecular motion stops. This contrasts with Celsius and Fahrenheit, which have arbitrary zero points. The Rankine scale is also an absolute scale, but it is not as widely used as Kelvin. Sources and related content

What is used to measure temperature?
Correct Answer
B. A thermometer
Explanation
A thermometer is used to measure temperature. It consists of a narrow glass tube with a bulb at one end that contains a liquid, usually mercury or alcohol. As the temperature changes, the liquid expands or contracts, causing it to rise or fall within the tube. The scale marked on the thermometer allows us to read the temperature accurately. A barometer is used to measure atmospheric pressure, a gasometer is used to measure the volume of gas, and a seismometer is used to measure seismic activity.

The following is a type of thermometer except for:
Correct Answer
D. Visual Thermometer
Explanation
The following is a type of thermometer except "Visual Thermometer." Digital thermometers, graphic thermometers, and computerized thermometers are all types of thermometers that provide temperature readings using various digital or graphical displays. "Visual Thermometer" does not correspond to a recognized type of thermometer and is not a commonly used term in the context of temperature measurement.
4.
All of the following are temperature scales except:
Correct Answer
A. Gabriel
Explanation
The question asks for a temperature scale that is NOT included in the given options. Gabriel is not a temperature scale, so it is the correct answer. Kelvin, Celsius, and Fahrenheit are all temperature scales commonly used to measure temperature.
5.
Water freezes at:
Correct Answer
B. 0 degrees Celsius
Explanation
Water freezes at 0 degrees Celsius. This is the temperature at which water changes from a liquid state to a solid state, forming ice. At temperatures below 0 degrees Celsius, water molecules slow down and come closer together, forming a crystalline structure. This process is known as freezing.
6.
Temperature is really a measure of how fast the atoms and molecules that make up a substance are moving.
Correct Answer
A. True
Explanation
Temperature is a measure of the average kinetic energy of the particles in a substance. The higher the temperature, the faster the particles are moving. This is because temperature is directly related to the speed of atoms and molecules. Therefore, the statement that temperature is a measure of how fast the atoms and molecules are moving is true.
7.
A digital thermometer shows the temperature on a scale or dial; an analog thermometer shows the temperature as a number.
Correct Answer
B. False
Explanation
Analog thermometers actually show the temperature on a scale or dial, while digital thermometers display the temperature as a number.
8.
Kelvin is a measure of temperature that is abbreviated Kln.
Correct Answer
B. False
Explanation
The statement is false because Kelvin is a measure of temperature that is abbreviated as K, not Kln.
9.
The degrees in Fahrenheit are smaller than those in Celsius.
Correct Answer
A. True
Explanation
This statement is true because the Fahrenheit scale has a smaller degree interval compared to the Celsius scale. The Fahrenheit scale divides the temperature range between the freezing and boiling points of water into 180 equal intervals, while the Celsius scale divides the same range into 100 equal intervals. Therefore, each degree on the Fahrenheit scale is smaller than each degree on the Celsius scale.
10.
Water freezes at 0°C and boils at 100°C.
Correct Answer
A. True
Explanation
Water freezes at 0°C and boils at 100°C. This is a well-known fact in science. When the temperature of water reaches 0°C, it undergoes a phase change from a liquid to a solid, forming ice. Similarly, when the temperature reaches 100°C, water undergoes another phase change from a liquid to a gas, forming steam. These temperature points are known as the freezing point and boiling point of water, respectively. Therefore, the statement "Water freezes at 0°C and boils at 100°C" is true.
11.
Temperature is measured in many different scales, including __________, ___________ , and __________ scales.
Correct Answer
Celsius
Fahrenheit
Kelvin
Explanation
Temperature is measured in different scales such as Celsius, Fahrenheit, and Kelvin. These scales are used to quantify the amount of heat or coldness in an object or environment. Celsius is commonly used in most of the world, Fahrenheit is used in the United States, and Kelvin is used in scientific and engineering applications. Each scale has its own reference points and increments for measuring temperature.

The fahrenheit scale was developed by_____________________.
Correct Answer
Gabriel Daniel Fahrenheit, gabriel daniel fahrenheit,
Explanation
Gabriel Daniel Fahrenheit is the correct answer for this question. He was a Polish-German physicist who developed the Fahrenheit scale in the early 18th century. The Fahrenheit scale is commonly used in the United States and a few other countries to measure temperature. It is based on the freezing and boiling points of water, with 32 degrees Fahrenheit being the freezing point and 212 degrees Fahrenheit being the boiling point at sea level. Fahrenheit's scale is still widely used in everyday life, especially for weather forecasts and temperature measurements in the United States.
13.
Normal human body temperature is ______________________.
Correct Answer
98 degrees F,98.6 F, 98 degree fahrenheit, 98, 98.6, 98 F
Explanation
The normal human body temperature is typically measured as 98 degrees Fahrenheit or 98.6 degrees Fahrenheit.
14.
An analog thermometer shows the temperature on a__________________.
Correct Answer
scale, Dial
Explanation
An analog thermometer shows the temperature on a scale, which is represented by a dial. The scale on the dial indicates the different temperature measurements, allowing the user to read the temperature accurately. The dial is usually marked with numbers or gradations that correspond to specific temperature values. By aligning the needle or pointer on the dial with the appropriate marking on the scale, the user can determine the temperature reading.
15.
A digital thermometer shows the temperature as a ___________________________.
Correct Answer
number, digit
Explanation
A digital thermometer shows the temperature as a number because it uses electronic sensors to measure the temperature and then displays the reading on a digital screen. The sensor converts the temperature into an electrical signal, which is then processed and converted into a numerical value that can be easily read and understood by the user. This allows for accurate and precise temperature readings, making it convenient for various applications such as medical, weather monitoring, and household use.
