Question

A gas fills a balloon at a temperature of 27 C and 101.325 kPa of pressure. What will the pressure of the balloon be if the gas is heated to 127 C?

Answer 1

135.1‬kPa

Explanation:

Given parameters:

T1 = 27°C

P1  = 101.325 kPa

T2 = 127°C

Unknown:

P2 = ?

Solution:

Using a derivative of the combined gas law where we assume that the gas has a constant volume, we can solve for the unknown.

 At constant volume:

           $\frac{P1}{T1} = \frac{P2}{T2}$

P1 is the initial pressure

T1 is the initial temperature

P2 is the final pressure

T2 is the final temperature

  Take the given temperature to K

T1 = 27 + 273 = 300K

T2 = 127 + 273  = 400K

 Input the variables:

    $\frac{101.325}{300} = \frac{P2}{400}$

  P2 = 135.1‬kPa
