For an extra 100 pts - include when it has potential and kinetic energy.
Answers may vary.
Fill in the blank: Phase changes occur from changes in __________ and/or _______________.
temperature, pressure
The state when there are multiple phases occurring at once and the kinetic energy is not changing
Equilibrium
Even when heated by the same sun, wet sand is much cooler than dry sand. Explain why, using specific heat capacity in your argument.
Wet sand has a much higher specific heat capacity as it is combined with water. The higher the specific heat, the harder it is for the sun to heat it up.
What type of energy occurs when mixing two chemicals together to form a new substance?
chemical energy
Name the 2 phase changes a substance goes through: Solid to a liquid is ________
Liquid to a gas is _________
melting, boiling or vaporization
How difficult it is to change the temperature of an object
Specific Heat Capacity
