PROBLEM 39P

A balloon with an initial volume of 3.2 L at a temperature of 299 K is warmed to 376 K. What is its volume at 376 K?

Solution 39P

Step 1:

Given :

Initial volume of balloon = 3.2 L

Initial Temperature = 299 K

Final Temperature = 376 K.

Final volume @ 376 K = ?

Charles’s law states that ‘At a fixed pressure, the volume of a gas is directly proportional to the kelvin temperature of the gas.’

Mathematically it can be represented as :

V T Or = k

where:

V = volume of the gas,

T = temperature of the gas (measured in kelvins),

k = constant.
