3. A weather balloon has a volume of 100,0 L when it is released from sea level, where the pressure is 101 kPa. What will be the
balloon's volume when it reaches an altitude where the pressure is
43.0 kPa?
4. 20. A volume of helium occupies 11.0 L at a pressure of 98.0 kPa.
What is the new volume if the pressure drops to 86.2 kPa?
5. what would happen to the volume of a gas if the pressure on it
were decreased and then the gas's temperature were increased.
6. Predict what would happen to the volume of a gas if the pressure
on that gas were doubled and then the absolute temperature of
the gas were doubled.
7. State Charles Law.
8. What is the equation for Charles Law
9. A 2.0-L balloon at room temperature (20.0°C) is placed in a

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
