Answer:
6.286 L.
Explanation:
Applying Charles Law,
V/T = V'/T'............................... Equation 1
Where V = Initial volume of the balloon, T = Initial Temperature of the balloon, V' = Final volume of the balloon, T' = Final Temperature of the balloon
make V' the subject of the equation
V' = VT'/T............................ Equation 2
Given: V = 6.50 L, T = 31 °C = (273+31) K = 304 K, T' = 21 °C = (273+21) K = 294 K
Substitute into equation 2
V' = 6.5(294)/304
V' = 6.286 L.
Hence the new volume in the balloon = 6.286 L.

Answer: I found this online. Hope it helps you.
Explanation:
This pressure is transmitted throughout the liquid and makes it more difficult for bubbles to form and for boiling to take place. If the pressure is reduced, the liquid requires less energy to change to a gaseous phase, and boiling occurs at a lower temperature.
