1
Q
specific latent heat of vaporisation
A
The amount of heat/energy needed to change the phase of one kilogram of liquid (liquid to gas/gas to liquid) at constant temperature/boiling temperature.
2
Q
Heat
A
Energy transfer due to temperature difference (between system and environment)
3
Q
Work
A
Energy transfer when a force exerted on a system is associated with a displacement
4
Q
Conservation of Linear Momentum
A
In an isolated (/closed) system, total momentum remains constant.
5
Q
Superposition principle (waves)
A
Displacement of a particle along the path of more than 1 wave, at any time, is the vector sum of the displacements due to each individual wave.
6
Q
Standing waves are formed via:
A
The interference of 2 oppositely moving, identical travelling waves
