A large garage with well-insulated walls and containing 700 m of air at 275 K is heated at constant pressure (atmospheric). Consider air to be an ideal diatomic gas. (a) Determine the energy (in kJ) required to increase the temperature of the air in the building by 1.10C. 5.50 How does the amount of heat required depend on the molar specific heat at constant pressure and the desired change in temperature? What is the value for the molar specific heat at constant pressure? How can you determine the number of moles of the gas? kJ (b) Determine the mass (in kg) this amount of energy could lift through a height 1.50 m. 0.374 How can you obtain the value for the change in gravitational potential energy? How is the change in gravitational potential energy related to the change in elevation? Don't forget that the value for the heat in part (a) is given in kJ. kg Need Help?
