| Question | Answer |
|---|---|
| What is a gas | A substance that has no boundaries but diffuses rapidly to fill any container its in |
| What is the standard atmospheric pressure value | 1x10^5 |
| What is the standard temperature value | 273K |
| Boyle's Law | At constant temperature the volume of a fixed mass of gas is inversely proportional to pressure |
| What can Boyle's Law be expressed as | V (proportional symbol) 1/P |
| Charles' Law | At constant pressure, temperature (in Kelvin) is proportional to the volume of a fixed mass of a gas |
| What can Charles' Law be expressed as | V (proportional symbol) T |
| Combined Gas Law | (p1v1)/T1=(p2v2)/T1 |
| Gay Lussac's Law | in a reaction between gases the volumes of the reacting gases and the volumes of any gaseous products are in the ratio of small whole numbers provided that they are measured at constant temp and pressure. |
| Avogadro's Law | equal volumes of gases contain equal numbers of molecules under constant temperature and pressure |
| One mole of any gases occupies how much under s.t.p | At s.t.p one mole of any gas occupies a volume of 22.4 litres |
| One mole of any gases occupies how much in room temperature | In room temperature one mole of any gas occupies a volume of 24 litres |
| What is an ideal gas | One that obeys all the assumptions of the kinetic theory of matter under all conditions of temperature and pressure |
| Melting Point | The temperature at which a solid turns into a liquid |
| Freezing Point | The temperature at which a liquid turns into a solid |
| Boiling Point | The temperature at which a liquid turns into a gas throughout the liquid |
| Evaporation | The changing of liquid to gas on its own surface |
| The random movement of particles is called what | Brownian Method |
| Assumptions of the kinetic theory of gases | There are no attractive or repulsive forces between the molecules of a gas / The volume of all molecules in a gas is negligible to the space they occupy / Collisions are perfectly elastic / |
| Limitations of the kinetic theory of gases | All gases do actually have attractive and repulsive forces between their particles. / The volume of the molecules of a gas isn't actually negligible to the space they occupy |
