Thermal Energy Review - EOU Quizs

How does the transfer of thermal energy occur?

• Faster moving molecules collide with slower moving molecules, speeding up the slower ones until they reach equilibrium.

• Thermal energy is transferred only through conduction, not convection or radiation.

• Heat transfer occurs only when there is a temperature difference between two objects.

• Molecules do not interact; thermal energy is transferred through electromagnetic waves.

Which sample will transfer energy to the other?

• Sample A will transfer energy to Sample B.

• Sample C will transfer energy to Sample A.

• Sample B will transfer energy to Sample A.

• Sample D will transfer energy to Sample B.

What is kinetic energy?

• The energy of motion that an object possesses due to its movement.

• The energy stored in an object due to its position.

• The energy released during a chemical reaction.

• The energy required to start a motion.

How do temperature and thermal energy relate to everyday life?

• They only affect cooking and heating systems.

• They influence weather patterns, cooking, heating systems, and many other aspects of daily life.

• They have no impact on daily activities.

• They are only relevant in scientific experiments.

What is the relationship between temperature and thermal energy?

• Temperature is a measure of the total kinetic energy of the particles in a substance.

• Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total kinetic energy.

• Temperature and thermal energy are the same thing.

• Temperature is unrelated to thermal energy.

What happens during a collision?

• Energy and momentum are transferred between colliding objects.

• Only energy is transferred, not momentum.

• Colliding objects come to a complete stop after the collision.

• Momentum is lost during the collision.

What is the law of conservation of energy?

• Energy can be created and destroyed.

• Energy can only be created.

• Energy cannot be created or destroyed, only transformed from one form to another.

• Energy is a constant that does not change.

What is the difference between potential energy and kinetic energy?

• Potential energy is the energy of an object in motion, while kinetic energy is stored energy based on an object's position.

• Potential energy is stored energy based on an object's position, while kinetic energy is the energy of an object in motion.

• Potential energy and kinetic energy are the same and can be used interchangeably.

• Potential energy is the energy of an object at rest, while kinetic energy is the energy of an object that is stationary.

What is thermal energy?

• The energy stored in chemical bonds of a substance.

• The total kinetic energy of all the particles in an object, which is related to its temperature.

• The energy associated with the motion of an object in a gravitational field.

• The energy released during a nuclear reaction.

What is a molecule?

• A molecule is a group of atoms joined together in a particular way.

• A molecule is the smallest unit of a compound that retains its chemical properties.

• A molecule is a single atom that cannot be divided further.

• A molecule is a type of chemical reaction between two or more elements.
