°C, and the pressure inside the balloon is 1 atmosphere. If the balloon is placed in a freezer at -10°C, what will be the new pressure inside the balloon assuming the volume remains constant?
To solve this problem, we can use the combined gas law equation:
(P1 * V1) / T1 = (P2 * V2) / T2
Given:
P1 = 1 atm (initial pressure)
T1 = 20 °C = 20 + 273 = 293 K (initial temperature)
T2 = -10 °C = -10 + 273 = 263 K (final temperature)
V1 = V2 (volume remains constant)
Plugging in the values into the equation:
(1 atm * V1) / 293 K = (P2 * V1) / 263 K
Cross-multiplying:
1 atm * V1 * 263 K = P2 * V1 * 293 K
Simplifying:
263 atm * V1 = P2 * 293 atm * V1
Dividing both sides by V1:
263 atm = P2 * 293 atm
Dividing both sides by 293 atm:
263 atm / 293 atm = P2
P2 ≈ 0.897 atm
Therefore, the new pressure inside the balloon when placed in the freezer at -10°C will be approximately 0.897 atm.
