Answer 2

Answer:

The three modes of heat of transfer are...

• Conduction
• Convection
• Radiation

Explanation:

The differences are:

Conduction:

1. In conduction,heat transfer takes place between objects by direct contact
2. The heat transfer takes place due to the difference in temperature
3. The heat transfer in conduction is slow
4. The heat transfer occurs through a heated solid Object
5. It doesn't follow the law of reflection and refraction.

Convection:

1. In convection,the heat transfer takes with in the fluid
2. The heat transfer occurs due to the difference in density
3. The heat transfer in convection is faster
4. The heat transfer occurs through intermediate Obects. For example, heat transfer between air and water
5. It doesnot follow the law of reflection and refraction.

Radiation:

1. In radation,heat transfer occurs through electromagnetic waves with out involving
2. The heat transfer occurs
