## Energy Transfer Questions and Answers

• 1.

### Thermal energy that is transferred from matter at a higher temperature to matter at a lower temperature is called ___________________.

• A.

Kinetic energy

• B.

Heat

• C.

Temperature

• D.

Potential energy

B. Heat
Explanation
Heat is the correct answer because it refers to the thermal energy that is transferred from matter at a higher temperature to matter at a lower temperature. Heat is a form of energy that is transferred through conduction, convection, or radiation, and it flows from objects with higher temperatures to objects with lower temperatures until thermal equilibrium is reached. This transfer of heat is what causes objects to warm up or cool down.

### Heat that is transferred from one particle of matter to another without the movement of matter is _________________.

• A.

Conduction

• B.

Convection

• C.

• D.

None of the above

A. Conduction
Explanation
Conduction is the correct answer because it refers to the transfer of heat between particles of matter without the actual movement of the matter itself. In conduction, heat energy is transferred through direct contact between particles, such as when a hot object is placed in contact with a cooler object and the heat is transferred from the hot object to the cooler one. This process occurs in solids, where the particles are closely packed and can easily transfer heat energy through collision and vibration.

### Heat that is transferred by the movement of currents within a fluid is _________________.

• A.

Conduction

• B.

Convection

• C.

• D.

None of the above

B. Convection
Explanation
Convection is the correct answer because it refers to the transfer of heat through the movement of currents within a fluid. In convection, heat is transferred as the fluid particles gain energy, become less dense, and rise, while the cooler particles sink, creating a continuous circulation of the fluid. This process is commonly observed in fluids such as air or water, where the warm fluid rises and carries heat away from the source, while the cooler fluid replaces it.

### Heat that is transferred by electromagnetic radiation is called _______________.

• A.

Conduction

• B.

Convection

• C.

• D.

None of the above

Explanation
Heat that is transferred by electromagnetic radiation is called radiation. Radiation refers to the transfer of heat through electromagnetic waves. Unlike conduction and convection, which require a medium to transfer heat, radiation can occur in a vacuum. When an object absorbs radiation, its temperature increases, and it emits radiation based on its temperature. This process is how heat from the Sun reaches Earth and warms its surface.

### A turtle basking in the sun is an example of _______________.

• A.

Conduction

• B.

Convection

• C.

• D.

Explanation
A turtle basking in the sun is an example of radiation because radiation is the transfer of heat through electromagnetic waves. In this case, the turtle is absorbing heat from the sun's rays without direct contact with any other object or medium. Conduction involves heat transfer through direct contact, convection involves heat transfer through the movement of fluids, and advection involves heat transfer through the movement of gases or liquids. None of these processes are applicable in the given scenario.

### Opening the windows in a hot room is an example of _________________.

• A.

Conduction

• B.

Convection

• C.

• D.

B. Convection
Explanation
Opening the windows in a hot room is an example of convection. Convection is the transfer of heat through the movement of a fluid, such as air or water. In this scenario, the hot air inside the room rises and escapes through the open windows, while cooler air from outside enters the room. This movement of air helps to equalize the temperature and cool down the room. Therefore, the correct answer is convection.

### Putting a ice on a sprained ankle is an example of ____________________.

• A.

Conduction

• B.

Convection

• C.

• D.

None of the above

A. Conduction
Explanation
Putting ice on a sprained ankle is an example of conduction because conduction is the transfer of heat or energy through direct contact between two objects or substances. In this case, the cold temperature of the ice is transferred to the ankle through direct contact, reducing inflammation and providing pain relief.

### A lava lamp does an excellent job demonstrating convection currents. What happens to the lava when it heats up?

• A.

Lava becomes less dense and sinks.

• B.

Lava become more dense and sinks.

• C.

Lava becomes less dense and rises.

• D.

Lava becomes more dense and rises.

C. Lava becomes less dense and rises.
Explanation
When the lava in a lava lamp heats up, it becomes less dense. This means that it becomes lighter and occupies more space compared to when it was cooler. As a result, it rises to the top of the lamp. This phenomenon is known as convection, where the warmer and less dense material rises while the cooler and denser material sinks. Therefore, the correct answer is that the lava becomes less dense and rises.

### How is heat transferred?

• A.

Heat is transferred from a warmer object to a cooler object.

• B.

Heat is transfferred from a cooler object to a warmer object.

• C.

Heat moves simultaneously through both objects.

• D.

None of the above

A. Heat is transferred from a warmer object to a cooler object.
Explanation
Heat is transferred from a warmer object to a cooler object because heat always flows from areas of higher temperature to areas of lower temperature. This is known as the principle of thermal equilibrium. When two objects of different temperatures come into contact, the molecules in the warmer object have more energy and collide with the molecules in the cooler object, transferring their energy and raising the temperature of the cooler object. This process continues until both objects reach the same temperature, achieving thermal equilibrium.

### How does a glass of lemonade become cold when you put ice in it?

• A.

Heat energy from the lemonade is transferred to the ice cube.

• B.

Heat energy from the ice cube is transferred to the lemonade.

• C.

Heat energy from the ice cube makes the lemonade cold.

• D.

None of the above

A. Heat energy from the lemonade is transferred to the ice cube.
Explanation
When ice is added to a glass of lemonade, heat energy from the lemonade is transferred to the ice cube. This is because heat always flows from a higher temperature object to a lower temperature object. The lemonade, which is at a higher temperature, transfers its heat energy to the ice cube, which is at a lower temperature. As a result, the lemonade loses heat and becomes colder.
