P3 Particle Model of Matter

?
what can the particle be used to explain?
1. the different states of matter 2. differences in density
1 of 14
what is internal energy?
where energy is stored inside a system by the particles (atoms and molecules) that make up the system.
2 of 14
what are changes of state?
physical changes which differ from chemical changes because the material recovers its original properties if the change is reversed.
3 of 14
internal energy is the total _______ energy and ________ energy of all of the particles (atoms and _______) that make up a _______.
kinetic, potential, molecules, system
4 of 14
what is the specific heat capacity of a substance?
is the amount of energy required to raise the temperature of one kilogram of the substance by one degree celcius.
5 of 14
what is latent heat?
the energy needed for a substance to change heat.
6 of 14
what is the specific latent heat of a substance?
the amount of energy required to change the state of one kilogram of the substance with no change in temperature
7 of 14
specific latent heat of fusion
change of state from solid - liquid
8 of 14
specific latent heat of vapourisation
change of state from liquid to vapour
9 of 14
what is work?
transfer of energy by a force
10 of 14
what can be done to gas?
compressed or expanded by pressure changes
11 of 14
what does pressure produce when gas is expanded or compressed?
produces a net force at right angles to the wall of the gas container
