A piston-cylinder device contains an ideal gas of nitrogen. At the initial state, the volume is V₁= 1.00 m³, the pressure is p₁= 400.00 kPa, the temperature is T₁= 300.00 K. An electric heater within the device is turned on for a time of At = 5.00 min. The current is I = 3.00 A, and the source voltage is V = 120.00 V. During the heating process, the gas expands, and a heat loss of Qout = 2.80 kJ occurs. The gas constant is R = 0.297 kPa.m³/(kg.K), and the room temperature specific heat at constant pressure is cp =1.039 kJ/(kg-K). Calculate the mass of the gas, m Gas (kg)

When an ideal gas undergoes isothermal compression as a closed system, its specific internal energy Decreases Does not change O Increases

N = 0 An insulated tank of volume 10+(10+N)/25 m and with a valve was filled with perfect tri- atomic gas at pressure 10 bar, where N is equal to the last two digitals in your student's ID number. Initially the valve was closed. A paddle wheel was mounted inside the tank and was run by 20 kW engine. The paddle wheel was turn on and at the same time the exit valve was opened. The gas temperature was constant though the whole process (due to very slow flow) and equal to 300 K. Calculate the time needed to decrease the pressure in the tank to 5 bar.

A typical gasoline (β=0.00095/°C)  tank can hold 65 liters (~17 gallons). At the gas station, the storage tank is underground and is maintained at a temperature of 50.0°F. On a hot day at 103.0°F you fill your empty tank. (a) What is the equivalent temperature difference in °C? A typical gasoline (β=0.00095/°C)  tank can hold 65 liters (~17 gallons). At the gas station, the storage tank is underground and is maintained at a temperature of 50.0°F. On a hot day at 103.0°F you fill your empty tank. (c) How much gas should you put in your car on this hot day at so that it will fill (not overfill) the tank when it expands to 103.0°F?
