Answer:
Charle's law.
Step-by-step explanation:
Charle's law:
According to Charle's law:
The volume of gas is directly proportional to the temperature when pressure and number of moles of gas are kept constant.
Mathematical expression:
V ∝ T
V = KT
V/T = K
when temperature is changed from T₁ to T₂ and volume is changed from V₁ to V₂.
V₁/T₁ = K and V₂/T₂ = K
V₁/T₁ = V₂/T₂
Their ratio remain constant for same amount of gas at same pressure.
