40dm3 of gas at 760 torr are heated from 5°c to 50°c what is the new volume

Explanation:

The pressure is constant, so we can use Charles' Law to calculate the volume.

Data:

V₁ = 40 dm³; T₁ =    5 °C

V₂ = ?;              T₂ = 50 °C

Calculations:

(a) Convert temperature to kelvins

T₁ = (   5 + 273.15) = 278.15 K

T₂ = (50 + 273.15) = 323.15 K

(b) Calculate the volume

the objects have the same charge.
