Question

The temperature of a balloon increases from 25 K to 50 K. What will the final volume of the balloon be if it was 1 L before the temperature change?

Answer 1

`"2 L"`

Explanation:

According to Charle’s law

`"V ∝ T"`

`"V"_2/"V"_1 = "T"_2/"T"_1`

`"V"_2 = "V"_1 × "T"_2/"T"_1 = "1 L" × (50 cancel"K")/(25 cancel"K") = "2 L"`
