Partcile Model Of Matter Flashcards
1
Q
Specific latent heat
A
The energy needed for a 1kg mass to changed state
2
Q
Internal energy
A
The energy stored by particles making up a system
Heating the system transfers energy to the particles increasing the internal energy
3
Q
Law of the conservation of mass
A
Mass is conserved when a substance changes state
4
Q
Particle motion in gases
A
Colliding gas particles creates pressure
Pressure is the total force exerted by all particles in the gas on a unit area of the container walls. Faster particles and more frequent collisions do this. Collisions exert a force. Pressure an volume are inversely proportional.
