An experiment needs to heat a small sample to 700 K, but the only available oven has a maximum temperature of 500 K. Could experimenter heat the sample to 700 K by using a large lens to concentrate the radiation from the over into the sample ?

A

Yes, if the sample is placed at the focal point of the lens

B

No, because it would violate the lawof conservation of energy.

C

No, becouse it would the second law of thermodynamics

D

Yes, if the areas of the fron of the oven is at least much as the area of the fron of the sample
