Front

What phase of matter exerts the most pressure on its container?

Back

gas

Front

What phase of matter has a definite volume but no shape?

Back

liquid

Front

Particles move the slowest because this state of matter has the least energy; very difficult to compress.

Back

solid

Front

The highest energy level and the most abundant state in the universe (because…stars!)
Options: solid, liquid, gas, plasma

Back

plasma

Front

What determines the state of matter of a substance?

Back

the amount of energy of the particles

Front

What occurs during an EXothermic reaction?

Back

heat is released; the area surrounding the reaction warms up

Front

What occurs during an ENdothermic reaction?

Back

heat is gained; the area surrounding the reaction cools off

Front

Which phase change occurs when a solid turns directly into a gas, skipping the liquid phase?

Back

sublimation

Front

What is the correct term for the phase change when a gas turns into a liquid?

Back

condensation

Front

Frost forming on a window in cold weather is an example of which phase change?

Back

sublimation
