1. What is energy transfer?
Energy transfer is the movement of energy from one place or object to another.
2. What are the three methods of heat transfer?
The three methods of heat transfer are conduction, convection, and radiation.
3. How do molecules behave when they’re heated?
When molecules are heated, they gain energy and move faster, which increases their kinetic energy.
4. What is temperature?
Temperature is a measure of the average kinetic energy of the particles in a system.
5. How is temperature measured?
Temperature is often measured using a thermometer, which detects changes in volume or pressure caused by changes in temperature.
