Question

1. Explain the natural phenomena in which
convection plays a role.
2. Why do some cooking vessels have copper bases
and plastic handles?
3. How can we say that heat from the sun reaches
the earth by radiation and not by conduction or
convection?
4. Give an example each to explain conduction,
convection and radiation from your everyday life.​

Answer 1

Explanation:

1.CONVECTION" : when the water is heated the water the near flame gets hot. The cold water from the sides moves down towards the heat. ... This process continues till the whole water (including cold water) gets heated. This process of heat transfer is known as"CONVECTION".

2.we know that copper is a good conductor of heat. the copper bases conducts heat well and thus the metal gets heated up faster and food gets cooked easily. however plastic is a bad conductor of heat. to prevent the handles from getting heated up it is made if plastic. otherwise it would be difficult to hold the vessel
