A certain amount of gas sample occupies 26.3 liters of volume at constant temperature and 740 torr pressure. How much should its volume in liters to increase the pressure of the gas to 1.62 atm under the same conditions?
A 0.71 m closed tank contains a gas at 129.52 kPa and 374.2 K. The gas is now
heated until its temperature increased to 607.8 K. The gas constant is 0.277
kJ/kg.K and the specific heat at constant volume is 0.554 kJ/kg.K. Determine the
mass of gas in the tank. [write your answer in kg and use 3 digits after the decimal
point].
Answer:
of water, oil, and mercury to be 1000 kg/m³, 850 kg/m², and
