A man heats a balloon in the oven. If the balloon initially has a volume of 0.4 liters and a temperature of 20°C. What will the volume of the balloon be after he heats it to a temperature of 250°C?

Answer 1

initial temp = 273 +20 = 293
final temp = 273 + 250 = 523
P V = n R T
n is constant
R is constant
P is constant
so
V/T = n R / P = constant
so
0.4 / 293 = V / 523
so
V = (523 / 293) * 0.4 liters
