Matter Flashcards
Density
The mass of something per volume
Irregular solid object
Object which is calculated in such a way that the volume cannot be calculated from its dimensions
Sublimate
Change from a liquid to a gas without becoming a liquid on the way
Internal energy
Total energy stored within a system, both kinetic and potential of all the atoms and molecules
Specific heat capacity
Amount of energy required to raise the temperature of one kg of the substance by 1 degree
Specific latent heat
Amount of energy required to change the state of one kg of the substance with no change in temperature
Specific lantern heat of fusion
From solid to liquid
Specific latent heat of vaporisation
From liquid to gas
Density =
Mass divided by volume
The upthrust has to be
The same or bigger that the weight to float
Energy transferred =
Mass x specific heat capacity x temperature change
Energy for a change of state =
Mass x specific latent heat
