Question

Pressure remaining the same, the volume of a given mass of an ideal gas increases for every degree centigrade rise in temperature by definite fraction of its volume at

A. $${0^ \circ }C$$  
B. absolute zero
C. its critical temperature
D. its Boyle's temperature
Answer :   $${0^ \circ }C$$
Solution :
According to Charle’s law “the volume of a fixed mass of a gas increases or decreases by $$\frac{1}{{273.15}}$$  of its volume at $${0^ \circ }C$$  for each degree rise or fall of temperature, if pressure is kept constant”.
