Question

If pressure of a fixed mass of a gas remains constant, then the volume of a gas will ……..
increase with increase in temperature
(b) decrease with increase temperature
(c) increase with decrease in temperature
(d) Volume not depends on temperature​

Answer 1

Charles' law states that the volume of a fixed mass of a gas increases or decreases by 1/273.15 of its volume at 0oC for each degree rise or fall in temperature, if pressure is kept constant.

$\text{hence \: \: (b) \: is \: correct \: option}$
