Term
KMT
Definition
explains forces between molecules and the energy they possess
Term
real vs. ideal
Definition
all gases are real but can come closer to ideal at high temperature with low pressure
Term
gases are made up of
Definition
atoms or molecules
Term
what happens to energy when gas molecules collide
Definition
energy is completely transferred btwn particles but none is lost
Term
gas molecule collisions are called
Definition
elastic collisions
Term
what gases have higher kinetic energies
Definition
gases at higher temperatures
Term
what determines the kinetic energy of a gas molecule
Definition
temperature
Term
why is kelvin used
Definition
so all values remain in positive and correlate to the kinetic energy
Term
characteristic of gases
Definition
1. expansion
2. fluidity
3. low density
