A balloon has a volume of 1.5 liters at 25.0 degrees Celsius. what would be the volume of the balloon if it were placed in a container of hot water at 90 degrees celsius?

Answer: 1.83Litres

Explanation:

From Charles Law, the volume of a given mass of gas is directly proportional to temperature, provided that pressure remains constant.

V1/T1 = V2/T2

V1 = 1.5L

T1 = 25+273=298K

T2 = 90+273 = 363K

V2=?

1.5/298 = V2/363

V2 = 1.5 * 363 / 298

V2 = 1.8L

Therefore at 90 degree Celsius, volume of the balloon is 1.8Litres
