KIDS TRIVIA

Detailed explanation-1: -Conduction is the transfer of heat energy from one substance to another or within a substance. Have you ever left a metal spoon in a pot of soup being heated on a stove? After a short time, the handle of the spoon will become hot.

Detailed explanation-2: -When a metal spoon is placed in a pot of hot soup, the molecules in the soup collide with those on the surface of the spoon, thereby transferring heat by conduction. Finally, fire warms the air above it, and the warmed air is less dense than the surrounding air, so it rises.

Detailed explanation-3: -For example, a spoon in a cup of hot soup becomes warmer because the heat from the soup is conducted along the spoon. Fun fact: Have you ever noticed that metals tend to feel cold? Believe it or not, they are not colder! They only feel colder because they conduct heat away from your hand.

Detailed explanation-4: -An example of conduction is a spoon warming up when it is placed into a cup of hot cocoa. Convection is the transfer of heat in air or a fluid through currents. An example is a pot of water warming up on a hot stove.

Detailed explanation-5: -This is an example of heat transfer by conduction.
