Clicker #1 0°C to 40°C is double the temperature of 0°C to 20°C. Does this mean you have twice the amount of kinetic energy in your system? A) Yes. If the temperature doubles then the kinetic energy must also double. They are directly related. B) No. Temperature is related to the heat energy of the gas particles, not the kinetic energy of the gas particles. C) No. Temperature is related to the kinetic energy of the gas particles but must be in relationship to the kelvin scale.

Clicker #2 A gas occupies a volume of 0.400 L at 0.661 atm. What will be its volume, at constant temperature, if the pressure is changed to 0.329 atm? Before any calculations are made, do you predict that the volume will increase, decrease, or stay the same? A) increase B) decrease C) stay the same

Clicker #3 Given 6.0 L of nitrogen gas at –25oC, what volume will the nitrogen occupy at 72oC? (Assume constant pressure.) Before any calculations are made, do you predict that the volume will increase, decrease, or stay the same? A) increase B) decrease C) stay the same
