- A piston-cylinder assembly contains 0.7 lb of air initially at a pressure of 30 lbf/in² and a temperature of 100°F. The air is heated at constant pressure until its volume is doubled. Assume the ideal gas model with constant specific heat ratio, k = 1.4. Determine the work and heat transfer, in Btu.arrow_forwardYou have a spherical heater, outside diameter = 3.40 cm, immersed in a container of water. In order to keep the water in the container heated to a constant temperature of 35.0°C you adjust the temperature of the spherical heater. You reach a steady-state condition when the surface temperature of the spherical heater is at 79.0°C. Assuming the electrical efficiency of the heater is 100.0%, calculate the power required by the heater (i.e., calculate q). Ignore radiation.arrow_forwardIn a certain thermodynamic process, 400 J of heat flows into a system, and at the same time the system expands against a constant external pressure of 8.00 × 10^4 Pa. If the volume of the system increases from 0.026 m^3 to 0.090 m^3, calculate the change in internal (thermal) energy of the system. If the internal (thermal) energy change is nonzero, be sure to indicate whether this energy change is positive or negative.arrow_forward
