- Air is compressed in an adiabatic compressor reversibly from 60.0 kPa and 20°C to 750 kPa. What percentage of work input is transferred to the air as thermal energy or heat? (Round the final answer to three decimal places.) 0% of work input is transferred to the air as thermal energy or heat.A gas undergoes an isothermal process at a constant temperature of 300 K. If the initial volume of the gas is 2 L and the final volume is 8 L, calculate the work done by the gas during the process.The energy released from condensation in thunderstorms can be very large. Calculate the energy (in J) released into the atmosphere for a small storm of radius 2.6 km, assuming that 2.5 cm of rain is precipitated uniformly over this area. (Assume that the rain is precipitated over a circular area and that the density of water is 1000 kg/m3.) _________J
