Question

. Dr. Hu has made some biocompatible prosthetics out of silk. The final processing step requires high pressure to remove any pores. The pressure on 1 kg of silk at room temperature is isothermally increased from 1 atmosphere to 100 atmospheres. The volumetric thermal expansion is -4.0×10-5/K, the isothermal compressibility is 2×10-10/Pa, and the heat capacity is 2000 J/K.

a)What was the work done?

b)What was the change in heat?

c)What would be the temperature change if this was done adiabatically?
