1. A balloon containing N2 gas has volume 4.80 L at a temperature 32.0 oC. The temperature is changed to -28.0 oC while still at a constant pressure of 762 torr. What will be the balloonâs new volume?
2.One mole of nitrogen gas at one atmosphere of pressure and 25 oC. How can a scientist increase the pressure of the gas
a. Hold the temperature constant and increase volume b. Hold the temperature constant and decrease the volume c. Hold the volume constant and decrease temperature
d. Hold the volume constant and decrease temperature
3.In two flasks of having equal volume, sample A contains H2 gas at 55°C and 2.00 atm and sample B contains O2 gas at 55°C and 2.00 atm. Which statement is FALSE?
Flask B has a higher mass of gas
If the temperature of flask B changes to 210 °C, the pressure of flask B will increase
If the temperature of flask B changes to 210 °C, the pressure of flask B will increase
The flasks have molecules with the same average speed will decrease
