Question

Use the References to access important values if needed for this question. In the following 2-D illustrations, assume that the gas molecules are in motion and that if there is a larger box it indicates a larger volume for the container holding the molecules. If both gas samples are at the same pressure, the sample in box A has the highest temperature. it is not possible to say anything about the relative temperatures. both samples are at the same temperature. the sample in box B has the highest temperature.

Explanation / Answer

Given

PA = PB

VA = VB

nA = 10 mol

nB = 30 mol

PV = nRT

PA VA = nA R TA ------> (1)

PB VB = nB R TB -------> (2)

equating (1) and (2) as pressure and volume are same ==> nA R TA = nB R TB

10 mole * TA = 30 mole * TB

TA / TB = 30 / 10 = 3

TA = 3 TB

so A will have higher teperature

Answer is first option
