Which would be best categorized as heat transfer by convection?

a) wearing a white shirt to stay cool on a summer day.

b) noodles rising and falling in a pot of boiling water

c) touching a metal spoon that is sitting in a pot of boiling water

eliminate

d) using a heating blanket to get warm

B

Explanation:

there are three modes of heat transfer which are

Conduction is a mode of heat transfer in solid materials

Convection refers to a mode of heat transfer of fluids in motion.

Radiation occurs when heat moves as energy waves in form of infrared radiation. The energy from the sun reaches us by radiation.

From the list of options;

option A refers prevention of heat transfer by radiation

option B refers to noodles rising and falling in a poy of boiling water. The path which the noodles move shows the convective path of the fluid.

option C refers to heat transfer by conduction

Option D refers to oth convection and radiation as modes of heat transfer.

option B best describes heat transfer by convection
