| What are the four basic properties of a gas sample? |
answer
|
question
| What do the gas laws describe? |
answer
| The relationships between pairs of the properties of gases. |
question
| What is the relationship between volume and pressure? |
answer
| There is an inverse relationship - an increase in one results in a decrease in the other. |
question
| What does Boyle's Law assume? |
answer
| Constant temperature and constant amount of gas. |
question
| What is Boyle's Law? |
answer
At a constant temperature, the volume occupied by a fixed amount of gas is inversely proportional to the applied pressure. P1V1=P2V2 |
question
| What is Charles's Law? |
answer
| At constant pressure, the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature. |
question
| How are volume and temperature related? |
answer
| Volume and temperature are linearly related. |
question
| If two variables are linearly related, what does that mean? |
answer
| Plotting one against the other on a graph produces a straight line. |
question
| What does extrapolate mean? |
answer
| To extend a graph past its plotted points. |
question
| What is the value of absolute zero? |
answer
| 0K |
question
| What is the combined gas law? |
answer
| A combination of Charles's Law and Boyle's Law. |
question
| What is Avogadro's Law? |
answer
| At fixed temperature and pressure, the volume of gas is directly proportional to the amount of any gas. |
question
| What does Guy-Lussac's Law assume? |
answer
| Constant volume and number of moles. |
