Question

A toy balloon is filled to 135 mL at a temperature of 22.5 °C (295.5 K). What temperature in Kelvin does it need to be heated to expand to 250 mL?

Answer 1

T2 = 547.2K

Step-by-step explanation:

Given:

V1 = 135 ml. V2 = 250 ml

T1 = 295.5K. T2 = ?

Using Charles's law and solving for T2,

V1/T1 = V2/T2

T2 = (V2/V1)T1

= (250 ml/135 ml)(295.5K)

= 547.2K (or 273.2°C)
