A fixed amount of ideal gas is held in a sealed container. The initial volume, pressure, and temperature are [recall that 1L = 10−3 m3, and 1atm = 101,300Pa] V = 40 L P = 2.5 atm T = 400 K. (a) Compute the new temperature if the pressure is reduced to P = 1.0atm while the volume is held constant. (b) Compute the new volume if the temperature increases to 600K while the pressure is reduced to 2.0atm. (c)...

2 attempts left Check my work Assume that the volume of a fixed amount of gas in a rigid container does not change. Calculate the pressure the gas would exert if the temperature were changed from 25.0°C to 0.0°C. The initial pressure of the gas is 817 torr. torr
The ideal gas law (PV=nRT) describes the relationship among pressure P, volume V, temperature T, and...
The ideal gas law (PV=nRT) describes the relationship among pressure P, volume V, temperature T, and molar amount n. Fix n and V When n and V are fixed, the equation can be rearranged to take the following form where k is a constant: PT=nRV=k or (PT)initial=(PT)final This demonstrates that for a container of gas held at constant volume, the pressure and temperature are directly proportional.The relationship is also called Gay-Lussac's law after the French chemist Joseph-Louis Gay-Lussac, one of...
