You decided to take a volleyball scuba diving with you. At the surface, the pressure is 752.0 mmHg and 25.0°C the volleyball has a volume of 2.00L. On your dive, you take it to a place where the pressure is 1520 mmHg and you note that the ball has a volume of 0.950L, what is the temperature of the place you took the volleyball to?
286 K = 13.1 °C
Which substance has indefinite shape AND volume? (Gas or Liquid)
Gas
What is Boyle's law?
Pressure will increase as volume decreases
Solve with Significant figures. 67.1cm - 45cm
22cm
Air, which is basically a mixture of nitrogen, oxygen and carbon dioxide, is captured in a box. The pressure of the nitrogen gas is 0.7765atm and the pressure of the carbon dioxide is 18.34mmHg. If the atmospheric pressure is 101.9Kpa, what pressure does oxygen put on the inside wall of the box in kilopascal?
20.80 kPa
Which substance has indefinite shape and definite volume? (Gas or Liquid)
Liquid
What is Guy-Lussac's Law?
Temperature and pressure of a gas are directly proportional
Solve with Significant figures. 5.0cm x 6.00cm
30.0cm2
In a controlled chemical reaction, 320.0g, which is 10.0 moles, of oxygen gas was produced at a temperature of 27.0°C and 16,600Kpa. What is the density of the oxygen gas under those conditions?
213 g/L
Define “boiling” without mentioning a temperature. Fully explain all terms for full credit.
When vapor pressure equals atmospheric pressure. Vapor pressure is the pressure exerted by evaporating molecules at a given temperature
What is Ideal Gas law?
PV=nRT
(Pressure x Volume= # of moles x Gas Constant x Temperature)
Solve with Significant figures. 38 g/L x 88L
3.3 x 103 g or 3300 g
At what temperature does 16.3g of nitrogen gas occupy a volume of 25,000mL at 950.0mmHg? [1mole of N2 = 28.00grams]
650 K
Give at least 3 assumptions of Kinetic Theory
1. Particles are hard spheres with NO VOLUME. 2. Particles are moving randomly on straight line paths 3. There are NO INTERACTIONS between particles 4. ALL collisions are 100% elastic
What is the combined gas law?
The combined gas law combines the three gas laws: Boyle's Law, Charles' Law, and Gay-Lussac's Law. It states the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant. PV/T=k
Solve with Significant figures.
(8.25 x 109 g) ÷ (5.0 L)
1.7 x 109 g/L
A neon sign is a lighting display made of glass tubes that have been filled with a gas. If the sign contained 425.0 ml of neon gas at 1.02atm at 25.0°C. Determine how many of atoms of neon are in the sign.
1.07 x 1022 atoms
