You probably use the term heat many times a day. As an example, when you cook dinner, you heat your dinner on a hot stove. When you place a piece of cool metal in the sun, it is heated by the sun’s energy. Why is heat the correct term to use in these examples?
They show that when objects are touching, they are the same temperature.
They show that heat flows from something warmer to something cooler.
They indicate that heat is created to raise the termperature of something.
They indicate that the kinetic energy of the particles decreases when something is heated.
Click the statement that is true.
Thermal energy transfers from the cooler object to the warmer object.
Thermal energy transfers from the warmer object to the cooler object.
Thermal energy does not transfer at all.
