A student investigates the link between the volume and pressure of a gas. The student uses a fixed mass of gas in a closed container. The student plots a graph of the results.
The student thinks that pressure multiplied by volume is always equal to the same number.
Explain why the student is correct.
Use data from the graph to support your answer.
Complete the sentences to explain how volume and pressure are related.
Use words from the list.
You can use each word once, more than once, or not at all.
| doubled | halved | the same |
If the volume of a gas is halved, the number of collisions per second between the gas
particles and the container is ..................................... .
The pressure is ..................................... .
The student then investigates how temperature and pressure of a gas are linked. The student measures the pressure of a gas as its temperature increases. The results are plotted on a graph.
Explain how temperature and pressure are linked.
Use the graph to support your answer.
