8. A balloon has a volume of 2500.0 ml on a day when the temp is 30.0°C. If the temperature at night falls to 10.0°C, what will be the volume of hte balloon if the pressure remains constant?

Use the formula:
v/T = v/T
For the formula to work, the temperature must be in degrees Kelvin, not degrees Celsius. Therefore, you must convert, by adding 273.
Temperature conversion:
30.0 + 273 = 303.0 K
10.0 + 273 = 283.0 K
Plug in numbers:
2500/303 = v/283
v = 2336 mL = 2.336 L
Note: Temperature increases with volume. If temperature is decreased, then volume should also decrease. Therefore, the answer makes sense.

The volume will fall to 283/303 of its previous value - you can work it out by converting the temperatures to Kelvin.

PV/T = PV/T Pis constsnt
V/T=V/T
V = 2500 (10+273)/(30+273)
V= 2335.0 ml
