Question

2. With an example of each, explain the uses of good and bad conductors of heat.
3. Describe the process of convection of heat.

Answer 1

Answer:

Good conductors of heat are used where we want to transfer heat faster from one point to the other. For example, cooking utensils are made of metals like brass, steel and aluminium, which are good conductors of heat. ... For example, handles of cooking utensils are made of wood or plastic, which are bad conductors of heat.

Answer 2

Answer:

2.=Answer. Good conductor of heat is allmetals which allow the heat to pass through them. Bad conductor of heat are plastics,wood,clay etc. This things do not allow heat a to pass through them.

3.=Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down. ...Convection currents within the earth move layers of magma, and convectionin the ocean creates currents.
