A graph is plotted with pV /T on y-axis and mass of the gas along x-axis for different gases. The graph is

Question 1

(a) a straight line parallel to x-axis for all the gases

(b) a straight line passing through origin with a slope having a constant value for all the gases

(c) a straight line passing through origin with a slope having different values for different gases

(d) a straight line parallel to y-axis for all the gases

Question 2

The correct option is (c) a straight line passing through origin with a slope having different values for different gases.

Explanation:

pV/T = nR = (m/M)R or pV/T = (R/M)m

i.e., pV/T versus m graph is a straight line passing

through origin with slope R/M, i.e., the slope depends on molecular mass of the gas M and is different for different gases.

The correct option is (c) a straight line passing through origin with a slope having different values for different gases.

Explanation:

pV/T = nR = (m/M)R or pV/T = (R/M)m

i.e., pV/T versus m graph is a straight line passing

through origin with slope R/M, i.e., the slope depends on molecular mass of the gas M and is different for different gases.
