the amount of energy required to raise the temperature of 1 kg of a substance by 1 Kelvin
What is condensation?
the change of a state that occurs when a gas becomes a liquid
What do heat engines convert thermal energy to?
The temperature reading of zero on the Kelvin scale is equal to _____.
Heat transfer by _______ can occur in a vacuum.
What is an insulator?
a material that does not conduct heat well
What happens to the temperature of a substance when a substance melts?
remains the same
In what kind of combustion engine is the fuel burned inside the cylinder?
What happens to the particles of a solid as the thermal energy of the solid increases?

Explain how a convection current is formed when you heat a pot of water on the stove.
the water near the heat source is warmed, warm water expands and rises while cool water sinks into its place (convection current)
