3Particle Model Changes StateMedium1 mark
A gas is placed in a sealed container.
The gas has a pressure of one atmosphere and a temperature of 50 C.
It is then heated to 100 C.
Which row describes the cause of the pressure of the gas and the effect of increasing the temperature of the gas?
| the cause of gas pressure | the effect of increased temperature on the gas | |
|---|---|---|
| A | collisions between gas particles and other gas particles | collisions between gas particles and other gas particles become less frequent |
| B | collisions between gas particles and other gas particles | the average velocity of the gas particles increases |
| C | collisions between gas particles and the sides of the container | collisions between gas particles and other gas particles become less frequent |
| D | collisions between gas particles and the sides of the container | the average velocity of the gas particles increases |
