Which statements below describe the changes that molecules undergo when heat is applied during a phase change? (select all that

The heat energy is used to move molecules further apart from each others.

When heat is applied, several phases of change occur , this is also known as a change of state. For example, when heating a liquid to make it a gas, also known as evaporation, you are making the spaces between the molecules even bigger because of the heat it suffered.

.

You multiply °C by 1.8 and add 32 = °F. If you don’t have a calculator / smartphone, you double it and subtract 10%.

Ex. (°F to °C):

100°C *1.8 = 180+32 = 212°F = boiling point of water.

100*2–10% +32; 100*2=200–10% (20) =180, +32 = 212°F

°F to °C :

212 - 32 = 180. 180 / 1.8 =
