Phase Change and Energy Flow Ben Reynolds Autumn Geerer-Vignes Jackson Hall

Phase changes Solid to liquid -> Liquid to gas Energy is absorbed Gas to liquid-> Liquid to solid Energy is released

Example of Phase Change

Energy Flow Hot to Cold High energy to Low energy Caused by nature trying to get everything to the same temperature

Question 1 When a liquid gains energy does it become a solid or a gas?

Question 2 When thermal energy is absorbed what are the phase changes that occur? Solid to Liquid and Liquid to gas

Question 3 Fill out the chart Liquid Solid Gas Liquid

Question 4 Does energy flow from hot to cold or cold to hot?

Question 5 What causes energy flow? Nature trying to balance temperature.
