Question

6.
A hot air balloon holds 7.40 x 10 liters of gas. In order for the hot air balloon to rise into the sky, it must
be heated to 120°C. Once the balloon is up in the air, the air needs to be cooled in order for the balloon
to land. If the temperature of the balloon is decreased to 40.0°C. what will the new volume of the gas
be?

I need help idk how to do this

Answer 1

Answer:

58.9 L

Explanation:

Using Charle's Law, $\frac{V_1}{T_1}=\frac{V_2}{T_2}$. T1 is 120 C and the initial volume is 74.0 Liters. The final temperature is 40 C. Make sure to convert these temperatures to kelvin by adding 273 to them. Plugging in what we know, solve for V2 and that is the final volume.
