1.
What is matter?
Correct Answer
D. All of the above
Explanation
Everything is matter.Matter is everywhere.
2.
What is volume?
Correct Answer
D. The amount of space taken up by an object
Explanation
Volume is the measure of the amount of space occupied by an object. It refers to the three-dimensional extent of an object and is independent of the material or weight of the object. It is commonly used to describe the capacity or size of an object, such as the volume of a container or the volume of a room. In this context, volume does not refer to the sound settings on an iPod or the weight of a man, but specifically relates to the physical space occupied by an object.

What is a graduated cylinder used to measure?
Correct Answer
B. Volume
Explanation
A graduated cylinder is a laboratory instrument used to measure the volume of a liquid. It is designed with markings on the side that indicate the volume of the liquid it contains. By filling the cylinder with the liquid and reading the measurement at the meniscus (the curved surface of the liquid), one can determine the volume accurately. Therefore, the correct answer is volume.
4.
What is inertia?
Correct Answer
A. The amount an object resists another force
Explanation
Inertia is the property of an object that describes its resistance to changes in motion or rest. It is the tendency of an object to keep moving in a straight line at a constant speed or to stay at rest unless acted upon by an external force. The correct answer, "the amount an object resists another force," accurately describes inertia as it highlights the object's resistance to changes in motion caused by external forces.
5.
What is thermal conductivity?
Correct Answer
B. The rate at which a substance transfers heat
Explanation
Thermal conductivity refers to the rate at which a substance transfers heat. It measures how quickly heat can move through a material, indicating its ability to conduct heat. A substance with high thermal conductivity will transfer heat rapidly, while a substance with low thermal conductivity will transfer heat slowly.
6.
Describe the 3 characteristics of solids
7.
When gas is forced into a smaller space it is called
Correct Answer
pressure
poop
Explanation
The term "pressure" refers to the force exerted by a gas when it is confined to a smaller space. This is a well-known scientific concept in physics and chemistry. On the other hand, "poop" is unrelated and does not have any scientific meaning in this context.
8.
When a liquid doesn't spill after going above the surface of it's container it is called
Correct Answer
surface tension
Explanation
Surface tension is a phenomenon that occurs when the molecules at the surface of a liquid are more strongly attracted to each other than to the molecules in the air above. This cohesive force creates a "skin" on the surface of the liquid, causing it to resist external forces, such as gravity, and preventing it from spilling over the edges of its container. The surface tension allows insects, for example, to walk on water without sinking.
9.
One of the characteristics of a liquid is
Correct Answer
no definate shape
no definate size
definate volume
made of molecules
Explanation
A liquid is a state of matter that does not have a definite shape, meaning it takes the shape of its container. It also does not have a definite size, as it can expand or contract depending on the temperature and pressure. However, a liquid does have a definite volume, which means it occupies a specific amount of space. Additionally, liquids are made up of molecules, which are tiny particles that are constantly in motion.
10.
One state is
Correct Answer
solid
liquid
gas
Explanation
The given answer is correct because it correctly identifies the three states of matter: solid, liquid, and gas. These are the three most common states in which matter can exist. In the solid state, particles are tightly packed together and have a fixed shape and volume. In the liquid state, particles are still close together but can move more freely, taking the shape of their container. In the gas state, particles are widely spaced and have no fixed shape or volume, instead filling the entire space available to them.
