Particle Model & Pressure
1. This question has 3 part(s).
1.1. The particles of a gas exert pressure on the walls of a container.
Which of the following rows correctly describes the relationship between pressure and the number of particle collisions with the walls of the container every second?
pressure | number of collisions with the walls of the container every second | |
A | increases | stays the same |
B | increases | increases |
C | decreases | stays the same |
D | decreases | increases |
1.2. A digital thermometer gives a temperature reading of 19 °C.
Convert this temperature to kelvin.
1.3. A small container contains helium gas at high pressure. It comes with a label stating the pressure and volume of the helium gas inside.
The helium gas from one small container is pumped into a large balloon which fills a final volume of 2200 cm3.
(i) State the equation linking the initial pressure, initial volume, final pressure and final volume of a gas.
[1]
(ii) Calculate the final pressure of the gas in the large balloon.
final pressure = .............................. MPa [2]
