Estimate the rate of rise of the leafs temperature

Reference no: EM13489201

A leaf of area 36cm2 and mass 4.8×10?4kg directly faces the Sun on a clear day. The leaf has an emissivity of 0.85 and a specific heat of 0.80 kcal/kg?K.

Part A Estimate the energy absorbed per second by the leaf from the Sun.

Part B Estimate the rate of rise of the leaf's temperature.

Part C Will the temperature rise continue for hours?

Part D Calculate the temperature the leaf would reach if it lost all its heat by radiation to the surroundings at 20?C.
