Answer:
The volume of a given mas of a gas is directly proportional to the temperature if the pressure remains constant
V is directly proportional to T
V=1/T
V=constant/T
Explanation:
Charles law states that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.
e.g., In winters as the temperature falls off, when you take a basketball outside in the ground the ball shrinks.
The mathematical equation that represents Charles law:
V₁/T₁ = V₂/T₂
where, V₁ = initial volume
T₁ = initial absolute temperature
V₂ = final volume
T₂ = final absolute temperature
The applications of Charles law has in daily life are:
- Helium balloons shrinks in a cold weather.
- The capacity of the human lung decreases in winter season. This makes difficult for the athletes to perform in winter season and it also makes it difficult for people to go jogging.
A gas-filled balloon experiment:
If a balloon is filled with air, it will shrink when cooled and the balloon expands if heated. This happens because the air inside the balloon, which is a gas molecules, occupies a smaller volume when it is cool, and occupies a larger volume when it is hot.
