How are absolute temperature and volume of a gas related?
1 Answer
The volume of a gas is directly proportional to its absolute temperature.
More specifically, for a fixed mass of gas at a constant pressure, the volume (V) is directly proportional to the absolute temperature (T). This is Charles’ Law.
V ∝ T
V = kT, where k is a proportionality constant.
Since k is a constant,
EXAMPLE
A gas has a volume of 30.0 cm³ at 30 °C (303 K). What is its volume at 60 °C (333 K)?
Solution
V₁ = 30.0 cm³; T₁ = 303 K; V₂ = ?; T₂ = 333 K
V₂ = V₁×
The absolute temperature increased by a factor of
