1)If I have 5.6 liters of gas in a piston at a pressure of 1.5 atm and compress the gas until its volume is 4.8 L, what will the new pressure inside the piston be? P1V1 = P2V2
(1.5 atm)(5.6 L) = (x)(4.8 L)
x = 1.8 atm

2)I have added 15 L of air to a balloon at sea level (1.0 atm). If I take the balloon with me to Denver, where the air pressure is 0.85 atm, what will the new volume of the balloon be? P1V1 = P2V2

(1.0 atm)(15 L) = (0.85 atm)(x)
x = 18 L

3)I’ve got a car with an internal volume of 12,000 L. If I drive my car into the river and it implodes, what will be the volume of the gas when the pressure goes from 1.0 atm to 1.4 atm? P1V1 = P2V2

(1.0 atm)(12,000 L) = (1.4 atm)(x)
x = 8600 L

Charles’s Law – Solutions

1)If I have 45 liters of helium in a balloon at 250 C and increase the temperature of the balloon to 550 C, what will the new volume of the balloon be?

[pic]

2)Calcium carbonate decomposes at 12000 C to form carbon dioxide and calcium oxide. If 25 liters of carbon dioxide are collected at 12000 C, what will the volume of this gas be after it cools to 250 C?

3)I have 130 liters of gas in a piston at a temperature of 2500 C. If I cool the gas until the volume decreases to 85 liters, what will temperature of the gas be? [pic]

Combined Gas Law Worksheet - Solutions

1)If I initially have 4.0 L of a gas at a pressure of 1.1 atm, what will the volume be if I increase the pressure to 3.4 atm?

(1.1 atm)(4.0 L) = (3.4 atm)(x L)
x = 1.29 L

2)A toy balloon has an internal pressure of 1.05 atm and a volume of 5.0 L. If the temperature where the balloon is released is 200 C, what will happen to the volume when the balloon rises to an altitude where the pressure is 0.65 atm and the temperature is –150 C?

(1.05 atm)(5.0 L)/(293 K) = (0.65 atm)(x L)/(258 K)
x = 7.11 L

3)A small research submarine with a volume of 1.2 x 105 L has an internal...

...Gaslaws have an impact on several aspects of our lives. The S.T.E.M I decided to explore deals a great deal in thermodynamics in the gaslaw I chose chemistry. First off I have to explain what is the broad practice of chemistry. Chemistry, a branch of physical science, is the study of the composition, properties and behavior of matter. Chemistry is concerned with atoms and their interactions with other atoms, and particularly with the...

ABSTRACT
Gases behave in a similar way over a wide variety of conditions because to a good approximationthey all have molecules which are widely spaced, and nowadays the equation of state for an ideal gas isderived from kinetic theory. The combined gas...

...measured collection of hydrogen gas will be used to determine the reaction stoichiometry and the valency of magnesium.
Introduction
Stoichiometry is a measure of relative amount of reactants to products in an experiment. In this experiment, a known mass of magnesium and volume of hydrogen gas collected is used to determine stoichiometry in this experiment.
A known mass of magnesium ribbon is mixed with hydrochloric acid to produce magnesium chloride and...

...Ideal GasLaw:
The ideal gaslaw is the equation of state of a hypothetical ideal gas. It obeys Boyle's Law and Charles Law.
Ideal GasLaw Formula :
General Gas Equation: PV = nRT
Pressure(P) = nRT / V
Volume(V) = nRT / P
Temperature(T) = PV / nR
Moles of Gas(n) = PV / RT
where,
P = pressure,
V = volume,
n = moles of...

This experiment is working with the ideal gaslaw, which is the summation of Boyle’s Law, where pressure is inversely proportional to volume, Charles’ Law,...

...Introduction
A gas is the state of matter that is characterized by having neither a fixed shape nor a fixed volume. Gases exert pressure, are compressible, have low densities and diffuse rapidly when mixed with other gases. On a microscopic level, the molecules (or atoms) in a gas are separated by large distances and are in constant, random motion. When dealing with gases, the Ideal GasLaw equation is the most famous equation used...

...objective of the experiment was to verify the molar volume of a gas and gas constant.¹ The method in which was used to determine the volume of H2 gas at standard temperature and pressure and the gas constant was to measure a strip of magnesium and place it inside the gas buret which contained hydrochloric acid, blue dye and distilled water and allow the reaction to occur. Once the reaction was complete and there were no...
