In summary, heat is the transfer of energy between objects due to a temperature difference. It can occur through conduction, convection, or radiation. Conduction involves physical collisions between molecules, while radiation involves the use of electromagnetic waves as intermediaries.

I always figured heat is the property of being 'jiggly' at a molecular level, and conduction is when a very 'jiggly' object comes in contact with another object and transfers that 'jigglyness' to the latter.
But how does radiating heat work? That doesn't make sense to me. Is heat a wave? That would explain how I can burn a piece of paper with a magnifying lens, but then conduction does not make sense to me.

Heat is the transfer of energy from one object to another due to a difference in temperature between the two. It is usually divided in three categories: conduction, convection, and radiation.

What you described is conduction, where it is indeed the physical collisions between the molecules of the objects that is responsible for the transfer of heat. In the case of radiation, it is an electromagnetic wave that is the intermediary between the two, instead of collisions.

Thanks, I think I get it now.
 

1. What is heat?

Heat is a form of energy that results from the movement of molecules. When molecules move faster, they have more heat energy.

2. How does heat transfer occur?

Heat transfer occurs through three main mechanisms: conduction, convection, and radiation. In conduction, heat is transferred through direct contact between molecules. In convection, heat is transferred through the movement of fluids such as air or water. In radiation, heat is transferred through electromagnetic waves.

3. How does molecular jigglyness relate to heat energy?

Molecular jigglyness, also known as molecular motion, is directly related to heat energy. The faster molecules move, the more heat energy they have. This is because heat is essentially the kinetic energy of molecules in motion.

4. What is the role of radiating waves in heat transfer?

Radiating waves play a significant role in heat transfer, particularly in the form of infrared radiation. This type of radiation is emitted by all objects and can be absorbed or reflected by other objects. In this way, radiating waves can transfer heat from one object to another.

5. How does understanding heat help in everyday life?

Understanding heat is crucial in everyday life as it has implications for several aspects of our lives. It helps us understand how our bodies regulate temperature, how different materials conduct heat, and how we can efficiently use heat for cooking and heating. It also plays a vital role in fields such as engineering, meteorology, and thermodynamics.
