Question

Describe three methods of heat transfer. Which of these methods can't take place in a vacuum? Why?

Option 1: Conduction, Convection, Radiation - Conduction can't take place in a vacuum due to the absence of matter for direct contact.
Option 2: Convection, Conduction, Reflection - Conduction can't take place in a vacuum due to the absence of matter for direct contact.
Option 3: Radiation, Conduction, Convection - Conduction can't take place in a vacuum due to the absence of matter for direct contact.
Option 4: Reflection, Conduction, Convection - Conduction can't take place in a vacuum due to the absence of matter for direct contact.

Answer 1

The three methods of heat transfer are conduction, convection, and radiation. Conduction cannot take place in a vacuum due to the absence of matter for direct contact.

Step-by-step explanation:

There are three main methods of heat transfer: conduction, convection, and radiation. Conduction is the transfer of heat between two objects in direct contact with each other. Convection is the transfer of heat through the movement of a fluid, such as air or water. Radiation is the transfer of heat through electromagnetic waves, such as sunlight.

Out of these three methods, conduction cannot take place in a vacuum due to the absence of matter for direct contact. In conduction, heat is transferred through physical contact between objects. In a vacuum, there is no material to come into direct contact with, so conduction is not possible.
