P6-Particle model of matter
Density of materials
Required practical activity 17:
use appropriate apparatus to make and record the measurements needed to determine the densities of
regular
and
irregular solid objects
and
liquids
. Volume should be determined from the dimensions of regularly shaped objects, and by a displacement technique for irregularly shaped objects.
method for a regular solid
method for an irregular solid
method for a liquid
what is the equation for density and name the units?
draw a simple diagram to model-
a solid
a liquid
a gas
describe the three states of matter in terms of structure, shape and movement of the particles-
solid
liquid
gas
Changes of state
describe what happens for each change of state
are these changes chemical or physical changes and
why
?
Internal energy
what is internal energy?
what is an internal system?
how does heating change the energy within a system?
Temperature changes in a system and specific heat capacity
what do temperature changes to a system depend on?
what is specific heat capacity?
what equation links changes in thermal energy with SHC and name the units?
Changes of heat and specific latent heat
what is latent heat?
label the difference phases of the graph
what is the specific latent heat of a substance?
energy for a change of state = mass × speci c latent heat-name the units
what is specific latent heat of fusion?
what is specific latent heat of vaporisation?
how are kinetic energy and temperature related?
Particle motion in gases
using the diagram, explain the effect of an increase in volume on pressure
what is the relationship the relation between the temperature of a gas and its pressure at constant volume?
