What is temperature?

• The ability to make things move or change

• The amount of molecules in the sample.

Harper, Mason, and Sophia are conducting a science experiment. They noticed that when they placed a hot metal spoon in a bowl of cold water, the water's temperature increased. What best describes this phenomenon?

• The movement of thermal energy from a warmer object (the spoon) to a cooler object (the water)

• The energy that the spoon has because it is moving

• The total kinetic energy of all molecules that make up the spoon or the water

• A group of atoms joined together in a particular way

Ava, Benjamin, and Aiden are studying for their physics exam. They start discussing the relationship between heat and temperature. Ava says that heat is the total kinetic energy, while temperature is the average kinetic energy. Benjamin thinks that heat and temperature are the same thing. Aiden believes that heat is the average kinetic energy, while temperature is the total kinetic energy. Who is correct?

• Ava: Heat is the total kinetic energy, while temperature is the average kinetic energy

• Benjamin: Heat and temperature are the same thing

• Aiden: Heat is the average kinetic energy, while temperature is the total kinetic energy

• None of them

• The kinetic energy decreases

• The kinetic energy remains the same

• The kinetic energy increases
