Physics Quiz

What is the main difference between heat and thermal energy?

• Heat is a substance, while thermal energy is a form of energy.

• Heat is the total energy of all moving particles, while thermal energy is always in motion.

• Heat is thermal energy that is being transferred from one place to another.

• Heat can be created and destroyed, while thermal energy cannot.

According to the law of conservation of energy, what happens to energy when it changes form?

• Energy is created.

• Energy is destroyed.

• Energy is transferred into heat only.

• Energy is never created or destroyed; it simply changes form.

What does temperature measure?

• The total energy of an object's particles.

• The average energy of motion of an object's particles.

• The ability of an object to transfer heat.

• The amount of heat an object contains.

Why does a lake have greater thermal energy than a glass of water at the same temperature?

• Because the lake has more heat.

• Because the lake has a higher temperature.

• Because the lake contains many more particles.

• Because the water in the lake is moving faster.

Thermal energy is transferred by how many main processes?

• One

• Two

• Three

• Four

What is conduction?

• The transfer of heat through electromagnetic waves.

• The transfer of heat that happens when particles collide with each other.

• The transfer of heat by the movement of fluids.

• The transfer of heat from the sun to the Earth.

Which states of matter can conduction occur in?

• Solids only

• Liquids only

• Gases only

• Solids, liquids, and gases

What is radiation in the context of thermal energy transfer?

• The transfer of heat through direct contact.

• The transfer of heat through the movement of fluids.

• The transfer of heat that happens when particles collide with each other.

• Energy that travels as electromagnetic waves.

Why does the handle of a pan get hot when it is placed on a stove?

• Because the handle absorbs heat from the air.

• Because the heat is transferred through radiation from the burner.

• Because the burner's particles collide with the particles in the bottom of the pan, transferring energy.

• Because the handle is made of a material that generates heat.

How can you feel the heat from a hot frying pan without touching it?

• Through conduction.

• Through convection.

• Through radiation.

• Through insulation.
