|
(Physics only) A gas can be compressed or expanded by pressure changes. |
|
(Physics only) What causes a gas to be compressed or expanded? |
|
|
|
(Physics only) A gas can be compressed or expanded by pressure changes. |
|
(Physics only) How does pressure affect gases? Demo - collapsing can to show changes in air pressure |
|
|
|
(Physics only) The pressure produces a net force at right angles to the wall of the gas container (or any surface). |
|
(Physics only) How does the pressure produce gas being compressed or expanded within a container? Class practical - investigate what happens to a gas with temperature change (cover conical flask and submerge in hot water observe what happens to gas pressure) |
|
|
|
(Physics only) Students should be able to use the particle model to explain how increasing the volume in which a gas is contained, at constant temperature, can lead to a decrease in pressure. |
|
(Physics only) Using the particle model, how does increasing the volume in which as gas is contained lead to a decrease in pressure? |
|
|
|
(MS)(Physics only) For a fixed mass of gas held at a constant temperature:
pressure ? volume = constant
p V = constant
pressure, p, in pascals, Pa
volume, V, in metres cubed, m3 |
|
(Physics only) What does Boyle's Law state? |
|
|
|
(Physics only) (MS) Students should be able to calculate the change in the pressure of a gas or the volume of a gas (a fixed mass held at constant temperature) when either the pressure or volume is increased or decreased. |
|
(Physics only) How could you calculate the change in pressure of a gas or the volume of a gas (of fixed mass and temperature) |

|
(Physics only) Work is the transfer of energy by a force. |
|
(Physics only) What is work? |
|
|
|
(Physics only) Doing work on a gas increases the internal energy of the gas and can cause an increase in the temperature of the gas. |
|
(Physics only) What impact does doing 'work' on a gas have on the internal energy of a gas and temperature? |
|
|
|
(Physics only) Students should be able to explain how, in a given situation eg a bicycle pump, doing work on an enclosed gas leads to an increase in the temperature of the gas. |
|
(Physics only) In a situation like a bicycle pump, explain how doing work on an enclosed gas can lead to an increase in temperature of the gas. demo - bike pump to show effects of work done |

(Physics only) In [Nuclear fusion] some of the mass may be converted into the energy of radiation. |
|
(Physics only) What happens to some of the mass in nuclear fusion? |
