A balloon filled with helium has a volume of 1.oo x 10^3 L at 20 degrees c. What will be the balloons volume at 30 degrees c, if the pressure surrounding the balloon remains constant?

• Chemistry -

At constant pressure, the volume of a fixed quantity of gas is proportional to the temperature, measured in °K.
To convert °C to °K, add 273.15.
So 20°C = 293.15°K, and
30°C = 303.15°K.

New volume
=1.00*10³*(303.15/293.15)
=?
