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.
A student likes to attend football games, no matter how cold and snowy the weather becomes. She is going to a game on a very cold day and takes along a hand warmer. She activates it and tucks it into the glove she is wearing. She holds her hands together, and before long, her hands are warm. Which best describes how her hands were warmed?
Heat was transferred by conduction, resulting in an increase in kinetic energy.
Heat was transformed by convection, resulting in the conservation of energy.
Thermal energy was transferred by currents, resulting in an increase in kinetic energy.
Heat was transformed by radiation, resulting in an increase in kinetic energy.
True or false? Conduction involves DIRECT CONTACT between two objects?
