The morning of a birthday party, a balloon is filled with 8.5 L of helium (He) when the temperature is 294 kelvin. The party starts at 4:00 p.m., at which time, the temperature has risen to 305 kelvin. What is the new volume of the balloon?

Answer:

The new volume is 4.15 L

Explanation:

Given

Initial Volume (,V1) = 4L

Initial Temperature (T1) = 294K

Final Temperature (T2) = 305k

Required

Determine the new volume (V2)

This will be calculated using ideal gas equation where pressure is constant.

We have

V1/T1 = V2/T2

Substitute values for V1, T1 and V2

4/294 = V2/305

Solve for V2

V2 = 305 * 4/294

V2 = 1220/294

V2 = 4.15L (approximated)
