You have two samples of the same gas in the same size container,with the same pressure.The gas in the first container has a Kelvin temperature four times that of the gas in the other container.The ratio of the number of moles of gas in the first container compared to that in the second is
A)1:1.
B)1:2.
C)1:4.
D)4:1.

According to the Ideal Gas Law, PV=nRT. Since the pressure and volume are the same for both gases, we can simplify the equation to n/T = constant. Therefore, the number of moles is directly proportional to the temperature. The temperature of the first container is four times that of the second container, so the number of moles in the first container is four times the number of moles in the second container. Therefore, the ratio of the number of moles in the first container to that in the second container is 4:1, which is choice D.
