Particle Model Of Matter Flashcards
What is the equation for density
M/V
What density Do solids have
Very high density
What is internal energy
Energy stored in a system by particles
What is the internal energy equation
Kinetic energy + potential energy
What is the change of state
Physical change
What is evaporation
When a liquid turns to gas but only on the surface
Why do you surface molecules of liquids only evaporate
Only the surface particles have enough energy to turn into a gas
What is specific heat capacity
The amount of energy required to raise the temperature of 1 kg of a substance by one degrees Celsius
What is specific latent heat
The amount of energy required to change the state of 1 kg with no temperature change
What is pressure
The frequency of particles colliding with the walls of the container
How can you increase pressure
Increasing the kinetic energy of the particles by increasing temperature
