Gas Vocab
pressure varies inversely with volume (temp is constant)
What is Boyle's Law?
The volume that the gas occupies at a pressure of 760. mmHg for a sample of oxygen gas collected in the lab which occupies a volume of 250. mL when its pressure is 720. mmHg.
What is 237 mL?
the phase change in which any remaining intermolecular forces of attraction are considered to be broken
What is vaporization (boiling)?
the unit that temperature must be in for gas law problems
What is kelvin?
force of collisions of gas particles per unit area
What is pressure?
Volume varies directly with temperature (constant pressure)
