Heat is essentially the transfer of energy between two places, all based on the existing temperature differences between the two. Do you know the different ways in which heat is transferred and how it is made possible? If you are in doubt, all you need to do is test your knowledge on heat transfer and their properties by taking this trivia quiz. Be sure to keep a lookout for other quizzes just like it.

• 1.

Which one is a form of heat transfer?

• A.

Conduction

• B.

Absorption

• C.

Refraction

• D.

Reflection

A. Conduction
Explanation
Conduction is a form of heat transfer where heat is transferred through direct contact between particles or objects. It occurs when there is a temperature difference between two objects in contact, causing the heat to flow from the hotter object to the cooler one. This process does not require the movement of the particles themselves, but rather the transfer of energy from one particle to another. Conduction is a common method of heat transfer in solids, such as when a metal spoon placed in hot soup becomes hot due to the transfer of heat from the soup to the spoon.

Rate this question:

• 2.

Conduction uses ___________ contact.

direct
Explanation
Conduction is a method of heat transfer that occurs through direct contact between objects. In this process, heat energy is transferred from a hotter object to a colder object through direct molecular collisions. Therefore, the correct answer is "direct" because conduction requires direct contact between the objects involved in the heat transfer.

• 3.

What type of heat transfer is the sun?

• A.

Convection

• B.

• C.

Conduction

Explanation
The sun emits heat through the process of radiation. Radiation is the transfer of heat energy through electromagnetic waves, without the need for a medium or direct contact. The sun's energy is emitted in the form of electromagnetic radiation, including visible light, infrared radiation, and ultraviolet radiation. This energy travels through space and reaches the Earth, warming it and providing light.

• 4.

What type of heat transfer is mainly seen with solids?

• A.

Convection

• B.

Conduction

• C.

B. Conduction
Explanation
Conduction is the transfer of heat through direct contact between molecules in a solid. In solids, the molecules are closely packed together, allowing them to easily transfer heat energy from one molecule to another. This type of heat transfer is mainly seen with solids because the particles in a solid are tightly bonded and do not have the freedom to move around like in liquids or gases, making convection and radiation less prevalent.

Rate this question:

• 5.

_____________ travels at the speed of light.

Explanation
Radiation travels at the speed of light because it is a form of energy that travels in the form of electromagnetic waves or particles. These waves or particles do not require a medium to propagate, allowing them to move through empty space at the maximum possible speed, which is the speed of light. This is a fundamental property of radiation and is supported by scientific evidence and theories such as Einstein's theory of relativity.

Rate this question:

• 6.

The heat from the core of the earth is called.

• A.

• B.

Convection

• C.

Conduction

C. Conduction
Explanation
Conduction is the transfer of heat through direct contact between particles or objects. In the context of the Earth, the heat from the core is transferred to the surrounding layers of the Earth's interior through conduction. This is because the core is extremely hot, and the heat energy is conducted or transferred to the adjacent layers, gradually heating them up. Convection, on the other hand, involves the transfer of heat through the movement of fluids or gases, while radiation is the transfer of heat through electromagnetic waves.

Rate this question:

• 7.

__________ travels in waves.

Explanation
Radiation travels in waves. Radiation refers to the emission of energy as electromagnetic waves or as moving subatomic particles. This energy can travel through space or other mediums in the form of waves, such as radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays. These waves carry energy and can transfer it from one place to another. Therefore, radiation is known to travel in waves.
