Kinetic Theory of Matter

Front

What happens to particles when the temperature of matter decreases?

Back

The particles slow down and move closer together.

Front

What is all matter made of?

Back

Particles that are constantly moving.

Front

What state of matter has a definite shape and a definite volume?

Back

Solid.

Front

What happens to chocolate molecules when chocolate melts?

Back

Chocolate molecules become faster and further apart.

Front

If an object has particles that are moving very slowly, what is the object's temperature likely to be?

Back

Cold.

Front

What is the Kinetic Theory of Matter?

Back

It states that all matter is made up of particles that are in constant motion.

Front

What happens to the speed of particles in a gas when the temperature increases?

Back

The particles speed up and move farther apart.

Front

What is the difference between solids, liquids, and gases in terms of particle arrangement?

Back

Solids have closely packed particles, liquids have loosely packed particles, and gases have widely spaced particles.

Front

How does heating affect the state of matter?

Back

Heating can cause solids to melt into liquids and liquids to evaporate into gases.

Front

What is the effect of cooling on gas particles?

Back

Cooling gas particles causes them to slow down and come closer together, potentially forming a liquid.
