The ideal gas law states that pressure is proportional to temperature and volume (PV = nRT). Therefore, the pressure of a gas sample at 15 degrees Celsius will be less than the pressure at 37 degrees Celsius because it has a lower temperature and the volume is the same.
To calculate the specific pressure at 15 degrees Celsius, we need to use the equation PV = nRT to determine the relationship between pressure and volume under two different temperatures. Plugging in the known values for temperature and volume, we find that the pressure at 15 degrees Celsius is 0.193 atm.
