Question

6. State whether each of the following is an example of conduction, convection, and/or radiation. Explain if you think there is more than one possibility.
(a)You are cooking, and the handle of the spoon you are using to stir the soup starts to feel hot.

(b)A pail of hot water is added to a child’s inflatable pool. After a while, the pool is warm.

(c)You go to the park, and when you sit on a metal bench, it is hot.

(d)You are standing near a barbecue, and you feel the heat on your face.

Answer 1

A).  Convection is heating the soup in the pot.
When you stick the spoon into the hot soup,
conduction heats the spoon all the way up to the end.

b).  Water conducts heat a little bit. 
But convection is much more responsible for the
uniform distribution of temperature in the kiddie pool.

c).  The heat from the metal bench conducts directly
to the buttus epidermis when you sit on it.

d).  You feel the heat on your face ... but not on the back of your
neck ... on account of radiation from the fire and the hot grill.
