Question

Explain two different methods for changing pressure with the help of an example

Answer 1

Answer:

1. First you could change the amount of molecules in the system. More molecules would mean more collisions. More collisions, more pressure. Decreasing the number of molecules would decrease the number of collisions and thereby decrease the pressure.
2. First you could change the amount of molecules in the system. More molecules would mean more collisions. More collisions, more pressure. Decreasing the number of molecules would decrease the number of collisions and thereby decrease the pressure.Second you could change the energy of the system by chaining the temperature. More energy would make the molecules move faster. Faster molecules would mean an increase in the number of collisions, More collisions mean a higher pressure.
