Question

A 3-kg copper block (Cv = 0.386 kJ/kg-K) is dropped from a small airplane traveling at 90.0 m/s at an elevation of 925 m above the ground. The temperature of the block is 10°C when it leaves the airplane, and 10.0 kJ of work is done on the block by air resistance as it falls to the ground. Determine the:

a) maximum possible temperature of the block at the instant it strikes the ground.
b) entropy change of the block during this process.
c) entropy change of the block plus the surroundings during this process.

Answer 1
