What does density depend on?
On how close its particles are to each other
What are the three states of matter?
Solid, liquid, gas
What is it called when solid, liquids + gas change?
Change of state
What is internal energy?
Energy stored inside a system by the particles
Internal energy is the total amount of what in a system?
Amount of kinetic energy and potential energy
What does heating do to kinetic energy?
What does it mean?
Increase it
Moves around faster
What does temperature change depend on?
How much energy is put into the system
Or mass of the substance
Or type of material it is made from
What specific heat capacity?
The amount of energy needed to raise the temperature of 1 kg of then material by 1 degree
What is latent heat?
The amount of energy needed for a substance to change state
What do gas particles do when they collide with something?
Exert pressure onto it
What is the pressure exerted by a gas directory proportional to?
The temperature of the gas at constant volume
