2.A gas syringe at 20°C contains 20.0 mL of CO2 gas. The pressure of the gas in the syringe is 1.0 atm. What is the pressure in the syringe at 20°C if the plunger is depressed to 10.0 mL?
3.A sample of SO2 gas has a volume of 5.2 L. It is heated at constant pressure from 30.o oC to 90.0°C. What is its new volume? (Hint: Which law will you apply of the pressure is constant
4.A sample of the inhalation anesthetic gas Halothane, in a 500-mL cylinder has a pressure of 2.3 atm at 0°C. What will be the pressure of the gas if its temperature is warmed to 37°C (body temperature)? (Hint: Which law will you apply if the volume is constant?)
