Report your answer to one decimal place using rounding. Assume that specific heats are constant.Please solve both subparts of the question below: Large helium-filled balloons are used to lift scientific equipment to high altitudes. a) What is the pressure, in atmospheres, inside such a balloon if it starts out at sea level with a pressure of one atmosphere and a temperature of 10.0°C and rises to an altitude where its volume is twenty times the original volume and its temperature is - 49.5°C ? b) What is the gauge pressure, in atmospheres, in the balloon then? (Assume the atmospheric pressure is constant.)Based on the table: What is the enthalpy of vaporization when converted to the unit cal/mol?

You can use the table above and assume that the vapor pressure depends linearly on the temperature between the existing data points. (b) What gauge pressure, in atmospheres, does this correspond to?
- The pressure, volume, and temperature of a mole of an ideal gas are related by the equation PV = 8.31T, where P is measured in kilopascals, V in liters, and T in kelvins.
