Two moles of a monatom1c ideal gas are at a temperature of 0°C and a volume of 45 liters. The gas is expanded adiabatically ( dQ = 0) and quasi-statically until its temperature falls to - 50°C. What are its imtial and final pressures and its final volume?
the combination of water and co2 molecules in the atmosphere accounts for approximately 150 wm2 in greenhouse heating.
Make use of dimensional analysis to determine how the pressure, p, will change when the fluid velocity, V, is doubled.
