the specific heat of a wax coating on a plant is 2400 j/kg degrees Celsius. During the day a 0.0055 kg coating of wax on a lead heats up from 15 to 22 degrees Celsius. How much radiant energy was absorbed by the wax?

Answers

The radiant energy was absorbed by the wax coating on the plant is determined as 92.4 J.

Heat absorbed by the wax

The heat absorbed by the wax is determined as follows;

Q = mcΔT

where;

m is mass of the waxc is specific heat capacityΔT is change in temperature

Q = 0.0055 x 2400 x (22 - 15)

Q = 92.4 J

Thus, the radiant energy was absorbed by the wax coating on the plant is determined as 92.4 J.
