Boyle's Law
Boyle’s law relates these two variables that effect gases.
Volume and pressure?
This is the type of relationship that exists between the two variables in Charles law.
direct
On a very cold day, what should happen to your car's tire pressure
It should decrease
A football inflated inside and then taken outdoors on a winter day shrinks slightly.
Charles law
states that at constant temperature for a fixed mass, the absolute pressure and the volume of a gas are inversely proportional.
Boyle's Law
Charles law describes a relationship between these two variables that effect gases.
Volume and Temperature
This law states that the pressure varies directly with the kelvin temperature when the volume remains constant.
Gay-Lussac's Law
Pushing in the plunger of a plugged-up syringe decreases the volume of air trapped under the plunger.
Boyle's law
When 85.0L of a gas at 104.4 atm is decreased to 21.0 atm, this is the new volume.
423L
The formula for Charles's Law
V1/T1 = V2/T2
This is the formula for Gay-Lussac's Law
P1/T1=P2/T2
The bubbles exhaled by a scuba diver grow as the approach the surface of the ocean. (The pressure exerted by the weight of the water decreases with depth, so the volume of the bubbles increases as they rise.)
Boyle's law
What is the formula for Boyle's Law
P1/V1=P2/V2
Why it is necessary to change the temperature to Kelvin’s when solving Gas problems?
there cannot be a negative V or P
You would expect the pressure to increase
when the temp increases
2.00 L of gas collected at 25.0°C and 99.3 atm. This is the volume at standard temp and pressure?
1.80L
A slightly underinflated rubber life raft left in bright sunlight swells up (Why shouldn't you overinflate your life raft when your ship goes down in tropical waters?)
Charles law
If the volume of a container is increased
the pressure decreases
The temperature of a 3.8 L container of gas is heated from 23°C to 45°C. What is the new volume?
4.1 L
This is held constant in Gay-Lussac's law
volume.
A dry gas has a pressure of 38.4 atm at 72.5 C. what will be the temperature of this gas at 80 atm
700 K
Firing a bullet. When gunpowder burns, it creates a large amount of superheated gas. The high pressure of the hot gas behind the bullet forces it out of the barrel of the gun.
