Why does your hand feel cold when you holding an ice cube?
What is your hand is losing thermal energy heat because it is transferring into the ice cube
You are supposed to get low toward the floor if you are ever caught in a building or house fire. The hotter air and smoke will rise and the cooler air will sink. What type of heat transfer does this represent?
What is Convection?
What is the Law of Conservation of Energy?
Energy cannot be created or destroyed, only transferred or transformed from one form to another

the unit of thermal energy is
What are joules
Transfer of thermal energy between materials by direct collision of particles.
What is Conduction
What type of heat transfer can occur without the presence of matter?
What is Radiation
Why do homes in warm climates often have white roofs?
What is to prevent radiation by reflecting light/heat off the house
If two objects are at the same temperature but have different masses, will they contain the same amount of thermal energy?
NO!
What has more thermal energy:
- A 100L pot of boiling water
- A 50L pot of boiling water
A 100L pot of boiling water (more mass= more energy!)
