The pressure, p, of a gas varies directly with its temperature, t, and inversely with its volume, v, according to the equation formula to find pressure, where n is the number of molar units and r is the universal gas constant. one molar unit of a gas has a pressure of about 1,245 joules at a temperature of 300 kelvin and a volume of 2 liters. what is the pressure of the same number of molar units of the gas at a temperature of 400 kelvin and a volume of 2.5 liters?
a)1,328 joules
b)1,900 joules
c)2,375 joules
d)2,600 joules
