Question

Heat is transferred to the surroundings by conduction , convection, and radiation. Research and explain how these modes help in the working of a) Heat convector b) Microwave c) Air fryer d) Geyser e) Hair dryer
Pls answer the question i will mark you the branliest

Answer 1

Answer:

answer is a

Explanation:

heat convector

Answer 2

The principle of working of the following gadget are,

a) Heat convector- Convection

b) Microwave- radiation

c) Air fryer- Convection

d) Geyser - Conduction and Convection

e) Hair dryer - Convection

Explanation:

• where is storage of water in the geyser. Due to the generation of the heat in the wire the geyser is set to warm the water by the process of conduction.

• Also there is development of the conventional current which provides uniform heat development

• In the hair dryer, the warm air is made to blow into the the hair which dries the hair.

• in microven there is  providance  of micro radiation which heats the food
