Question

A balloon has a volume of 0.5 L at 20°C. What will the volume be if the balloon is heated to 150°C?

Answer 1

Solution:

By using the formula of Charles's law.

We know that Charles's law states that the volume of a gas is directly proportional Kelvin temperature.

V1/T1 = V2/T2 ( T in Kelvin)

Here,

* 'T' refers to temperature.

* The SI unit of temperature is Kelvin.

20°C = 20 + 273 = 293 K

150°C = 150 + 273 = 423 K

0.5/293 = V2/423

=> V2 = 0.5 × 423/293

So, V2 = 0.72 L

Thus, the volume be if the balloon is heated to 150°C is 0.72 L.
