Determine the time required for the center temperature of a 3 cube to reach 808C. The cube has a volume of 125 cm . The thermal conductivity of the material is 0.4 W/(m 8C); density is 950 kg/m3; and specific heat is 3.4 kJ/(kg K). The initial temperature is 208C. The surrounding temperature is 908C. The cube is immersed in a fluid that results in a negligible surface resistance to heat transfer.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
