Paricle Model Of Matter Flashcards
What is the equation for the density of a material
Density = mass/voulme
What is the letter for density
P
What is density measured in
Kilograms per meter cube (kg/m3)
What is the letter for volume
V
What is volume measured in
Cubed (m3)
What can the particle model explain
-The diff states of matter
-differences in densitys
Where is energy stored
Inside a system by the particles that make up the system which is called internal energy
What is internal energy
The total kinetic energy and potential energy of all the particles that make up a system
How does headstrong change energy stored
It changes the energy stored by inc teh energy of the particles that make up the system which either raises the temp of the system or produce a change in state
What happens if the temperature of the system increases
The inc in the temp depends on the mass of the substance heated , the type of material and the energy input to the system
What is change of thermal energy written as
^E
How is change of thermal energy measured
Joules (J)
What is the specific heat capacity of a substance
The amount of energy required to raise the temp of one kilogram of ten substance by one degree celcius
Describe the latent heat
The energy needed for a substance to change state
What is the specific latent heat
The amount of energy required to change the state of one kilogram of the substance with no change in temp
