Mini-Quiz: Changing States of Matter

by Ron Kurtus (updated 8 February 2022)

Take this Mini-Quiz to check your understanding of the lesson material.

1. When is condensation seen outside?

When moist air condenses into rain

Condensation can only occur inside

When water becomes a solid

2. Why doesn't the temperature of a material keep rising when reaching the melting point?

The melting point is the highest temperature possible

Energy is required to change the state from solid to liquid

Energy is given off when the material melts

3. Why isn't a mercury thermometer good to use near the North Pole?

Mercury is too magnetic to use near the North Pole

Mercury is too expensive to use in a thermometer

The mercury may freeze at very cold temperatures near the North Pole

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.

Sometimes change can be good
