Density equation
Density= mass/volume
Sublimate
The transition of somethinf straight from solid to gas
What is internal energy
The total kinetic and potential energy of all particles that make up a system.
What does heating do to the energy in a system
It changes the energy stored within the system by increasing the energy of the particles. This either raises the temperature orbthe state of the system
What is the equation for increase in thermal energy
Change in thermal energy= mass x speceifc heat capacity x temperature change
What is latent heat
The energy needed for a substance to change state
What is specific latent heat
The amount of energy required to change the state of one kilogram of the substance with no change in temperature
Equation for energy for a change of state
Energy for a change of state= mass x specific latent heat
What happens to gas if you change The temperature
It changes the pressure exerted by the gas
