Question

For a fixed mass of gas at constant pressure, which of the following statement(s) is/are correct?

• A. Plot of volume versus Celsius temperature is linear with intercept zero
• B. Plot of volume versus Kelvin temperature is linear with a non-zero intercept
• C. plot of V/T versus $T$ is linear with a positive slope
• D. Plot of V/T versus $T$ is linear with a zero slope

Answer 1

Answer: (A), (D)

The correct options are
A Plot of volume versus Celsius temperature is linear with intercept zero
D Plot of V/T versus $T$ is linear with a zero slope

Given : For a fixed mass of gas at constant pressure, which of the following statement(s) is/are correct?

Solution :

For a fixed mass of gas at constant pressure, the volume is directly proportional to the kelvin temperature.

That means, for example, that if you double the kelvin temperature from, say to 300 K to 600 K, at constant pressure, the volume of a fixed mass of the gas will double as well.

You can express this mathematically as

V = constant x T

Plot of volume versus Celsius temperature is linear with intercept zero

Plot of V/T versus T is linear with a zero slop

The Correct Opt = A , D
