A large cylindrical tank contains 0.720 m3 of nitrogen gas at 27.0 ∘C and 8350 Pa (absolute pressure). The tank has a tight-fitting piston that allows the volume to be changed.What will be the pressure if the volume is decreased to 0.460 m3 and the temperature is increased to 155 ∘C? My answers have been coming up wrong so I need help with this one
Given,
V1 = 0.72 m3 ; T1 = 27 Deg C = 300 K ; P1 = 8350 Pa
V2 = 0.46 m3 ; T1 = 155 Deg C = 428 K ; P2 = ?
We know that,
P1V1/T1 = P2V2/T2
P2 = P1V1T2 / V2T1
P2 = 8350 x 0.72 x 428 / 0.46 x 300 = 18646 Pa
Hence, P2 = 18646 Pa.

A large cylindrical tank contains 0.760 m3 of nitrogen gas at 30.0 ∘C and 1.50×105 Pa (absolute pressure). The tank has a tight-fitting piston that allows the volume to be changed. What will be the pressure if the volume is decreased to 0.470 m3 and the temperature is increased to 151 ∘C?
A large cylindrical tank contains 0.850 m3 of nitrogen gas at 28.0 ∘C and 8.50×103 Pa (absolute pressure). The tank has a tight-fitting piston that allows the volume to be change What will be the pressure if the volume is decreased to 0.450m ^3 and the temperature is increased to 165 C?
A cylindrical tank has a tight-fitting piston that allows the volume of the tank to be changed. The tank originally contains 0.100 m3 of air at a pressure of 3.40 atm. The piston is slowly pulled out until the volume of the gas is increased to 0.380 m3. If the temperature remains constant, what is the final value of the pressure?
A cylindrical tank has a tight-fitting piston that allows the volume of the tank to be changed. The tank originally contains 0.120 of air at a pressure of 3.50 . The piston is slowly pulled out until the volume of the gas is increased to 0.430 . If the temperature remains constant, what is the final value of the pressure?
(a) A large, open at the top, upright cylindrical tank contains a brine with a density of 1.23 x 103 kg/m. If the air pressure is 101.3 kPa, determine the absolute pressure (in Pa) in the fluid at a depth of 27.0 m. 1269.16 The absolute pressure at any point in the fluid is the sum of atmospheric pressure and the pressure due to the depth of the fluid. How can you account for the pressure due to the depth...

A piston contains 580 moles of an ideal monatomic gas that initally has a pressure of 1.06 x 105 Pa and a volume of 1.3 m3. The piston is connected to a hot and cold reservoir and the gas goes through the following quasi-static cycle accepting energy from the hot reservoir and exhausting energy into the cold reservoir. The pressure of the gas is increased to 4.06 x 105 Pa while maintaining a constant volume. The volume of the gas...
A rigid tank contains 54.5 g of chlorine gas (Cl2) at a temperature of 72 °C and an absolute pressure of 5.60×10^5 Pa. The mass per mole of Cl2 is 70.9 g/mol. a) Determine the volume of the tank. b) Later, the temperature of the tank has dropped to 33 °C and, due to a leak, the pressure has dropped to 3.40×10^5 Pa. How many grams of chlorine gas has leaked out of the tank? (The mass per mole of...
