What is STP (standard temperature and pressure)
300

when measured at the same temp and pressure, volume of gases reactants and products of chemical reactions are always in simple ratios of whole numbers 

What is Gay-Lussac's Law of combining volumes 

300

A 8.3 L gas sample at standard pressure is compressed to a volume of 2.8 L and the temperature is increased from 30˚C to 65˚C. What is the new pressure of the gas in atms?

What is 3.3 atm

300
Gases consist of larger number of tiny particles, particles of a gas are in constant motion, the collisions between particles and their container are elastic, theare are no attractive or repulsive forces between gas particles, and the average kinetic energy of the particles of a gas is directly proportional to the Kelvin temperature of the gas.
What is the Kinetic Theory of Matter.

DAILY DOUBLE! A gas’s pressure doubles while its Kelvin temperature is halved. How does its volume change

What is the volume stays the same

400

DAILY DOUBLE! When hydrogen gas is collected over water at 30˚C, (water vapor pressure 31.8 mmHg) the partial pressure of the hydrogen gas was determined to be 732.8 mmHg. What was the barometric pressure at the time the gas was collected? (the barometric pressure equals the sum of the partial pressures)

What is 765 mmHg

400
Real vs. Ideal: 1.) Particles of a gas occupy space and have mass. 2.) Particles of a gas exert attractive forces on one another.
