Use the chart above or from your Unit 2 Guided Notes to determine which gas law would best help you solve the problem seen here. (1 point)

a gas contained in a balloon has a volume of 2.5 L at 25c and1 atm of pressure at sea level if we take that balloon mountain climbing with us on a field trip to mount mckinley where the temperature is 8.0c and 0.74 atm what would happen to the volume of our balloon?

To determine what happens to the volume of the gas in the balloon when the temperature and pressure change, we can use the Combined Gas Law. The Combined Gas Law relates pressure, volume, and temperature of a gas and is expressed as:

\[ \frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2} \]

Where:

  • \(P_1\) and \(V_1\) are the initial pressure and volume,
  • \(T_1\) is the initial temperature in Kelvin,
  • \(P_2\) and \(V_2\) are the final pressure and volume,
  • \(T_2\) is the final temperature in Kelvin.

Since you are changing both the temperature and pressure, the Combined Gas Law is the most appropriate choice for this scenario.
