Question

How atoms and molecules are affected by heat?

Answer 1

Hint: As we say heat, we are directly referring to temperature. Every object consists of atoms, and molecules theses collide with each other like people in the crowd, and this is known as kinetic energy of matter.

Complete answer:
- The kinetic energy theory tells us about the energy and what will happen to the energy when we heat something.
- If we put a vessel full of water on a hot stove, we make the molecules in the water move around more quickly and collide with each other.
- As more heat is supplied, molecules tend to move faster. And these molecules start moving apart.
- Eventually, they collide around so much that they break apart from one another. At this point, the liquid, which is being heated turns into a gas, the water becomes vapor and starts to evaporate away.
- Thus, we can easily state that heat affects atoms and molecules such that the rate of the reaction is increased, and the total volume is increased.

Additional information:
Transfer of heat takes place in different ways, namely: convection, conduction, and radiation. Convection is a way in which heat flows through liquids and gases. Conduction mostly happens in solid state. Radiation is the way we get heat energy from the sun.

Note:
Heat is the energy stored inside an object. The coldness and hotness of an object is measured by temperature. Temperature is a measure of the average kinetic energy of the molecule or particles in an object, which is a type of energy associated with motion.
