Verified by Toppr

From ideal gas equation, PV = nRT
so P-T curve at constant volume is a straight line.
If the temperature is written in Kelvin, it turns out that the intercept is at 273

Q1

Assertion: V-t graph for gas at constant pressure is a straight line passing through origin (t-temperature in Celsius)

Reason: volume is directly proportional to temperature (kelvin) at constant pressure.

Q2
Pressure versus temperature graph of an ideal gas at constant volume V is shown by the straight line A. Now mass of the gas is doubled and volume is halved, then the corresponding pressure versus temperature graph will be shown by the line.
