| Question | Answer |
|---|---|
| Temperature above which a substance can't be liquified no matter how much pressure is applied | Critical temperature |
| Nitrous oxide can not liquify if temp is | 37.5 C |
| At this temperature, N2O will turn into a solid | 36 C |
| Critical temperature of Nitrous Oxide is | 36.5 C |
| N2O is in a gas state at this temp | 40 C |
| Heating & cooling of a gas occurs due to change in the pressure is called | Adiabatic process |
| Example of a tire deflating is an example of | Adiabatic cooling |
| Pumping air into a tire is an example of | Adiabatic heating |
| Adiabatic cooling is defined as | occurs when the pressure fo a gas is decreased, as it expands into a larger volume |
| Adiabatic heating is defined as | occurs when the pressure of a gas is increased |
| Joule-Thompson Effect | compressed gas is allowed to escape freely into space & causes adiabatic cooling |
| N2O cylinder has a full tank at_____-Liters | 1590L |
| In a N20 cylinder, pressure stays constant until the volume of the cylinder drops below_____L | 400L |
| Latent heat is described as | heat lost as liquid vaporizes and temperature falls |
| What is the color of a N2O cylinder | Blue |
| What is the color of a O2 cylinder | green |
| What is the color of a Air cylinder | Yellow |
| when latent heat of vaporation occurs as.... | liquid vaporizes |
| When there is no more liquid in a N2O tank.... | pressure drops |
| What does nitrous need to prevent explosions? | Compressible gas |
| How do you restore pressure of a Nitrous cylinder? | turn cylinder off |
