What will be the new volume when 128 ml of gas at 20.0°c is heated to 40.0°c while pressure remains unchanged? what will be the new volume when 128 ml of gas at 20.0°c is heated to 40.0°c while pressure remains unchanged? 64.0 ml 256 ml 120. ml 137 ml 128 ml

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

Which accounts for an increase in the temperature of a gas that is kept a constant volume
