Which situation is an example of transferring heat by means of convection?
a. the sun warming the earth
b. the weather patterns outside
c. you toasty-warm in some footy pajamas
d. you accidentally grabbing the hot pan from the oven

b. the weather patterns outside

Explanation:

There are three modes of heat transfer:

1. Conduction: This type of heat transfer happens when there is direct contact between the two object.

2. Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas).

3. Radiation: This type of heat transfer happens when there is direct transfer of energy through space.

a. The sun warming the earth  is through radiation as there is no direct contact.

b. The weather patterns outside  are created due to the convection currents which arises due to movement of hot fluid upwards due to less density and the cold fluid downwards due to more density.

c. You toasty-warm in some footy pajamas  is an example of conduction as there is direct contact.

d. You accidentally grabbing the hot pan from the oven is an example of conduction as there is direct contact.

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff

explanation:

it is the second option.
