Question

A child receives a balloon filled with 47 L of helium from a vendor at an amusement park. The temperature outside is 320 K. What will the volume of the balloon be when the child brings it home to an air-conditioned house at 295 K? Assume that the pressure stays the same. Answer in units of L.​

Answer 1

43.3 L

Step-by-step explanation:

Applying,

V/T = V'/T'................... Equation 1

Where V = Initial volume of the ball0on, 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

From the question,

Given: V = 47 L, T = 320 K, T' = 295 K

Substitute these values into equation 2

V' = (47×295)/320

V' = 43.3 L
