A)31.6 mL
B)37.4 mL
C)0 mL
D)Heating a gas from a negative temperature to zero will cause it to explode because it then will be unstable
E)It is not possible for a gas to have a temperature of -22°C

According to Charles' Law, at constant pressure, the volume of a gas is directly proportional to its temperature. Therefore, if the temperature increases from -22°C to 0°C, the volume of the gas will also increase proportionally. Using the formula V1/T1 = V2/T2, where V1 is the initial volume, T1 is the initial temperature in Kelvin, V2 is the final volume, and T2 is the final temperature in Kelvin, we can solve for V2. First, we need to convert the initial temperature from Celsius to Kelvin by adding 273.15: -22°C + 273.15 = 251.15 K. The final temperature is 0°C + 273.15 = 273.15 K. Plugging in the values, we get: (34.4 mL)/(251.15 K) = V2/(273.15 K). Solving for V2, we get V2 = (34.4 mL)(273.15 K)/(251.15 K) = 37.4 mL. Therefore, the new volume of the gas is 37.4 mL.
