Which law states that the volume of a fixed amount of gas is inversely proportional to its pressure at a constant temperature.
Boyle's Law
100
What does V, T, and P stand for?
Volume, Temperature, and Pressure.
100
What is Constant in Boyle's Law? (Gas, Temperature, Pressure, Volume?)
The Amount of gas and Temperature.

A sample of nitrogen gas at 50°C and a volume of 2.5 liters is cooled to 25°C. What is the new volume?
V2= 2.3 L
100
The popping of a Balloon When we try to squeeze a balloon we are actually trying to reduce the volume of the gas inside, which increases the pressure. Since the balloon cannot withstand the added pressure it bursts.
Boyle's Law
200
Which law states that the volume of a fixed amount of gas is directly proportional to to its kelvin temperature at a constant pressure.
Gay-Lussac's Law
200
What is the formula for Charles's Law?
V1 / T1 =V2 / T2
200
What is constant in Charles's Law? (Gas,Temperature, Pressure, Volume?)
The amount of gas and pressure.
200
Find the new volume if the initial volume is 100 mL at a pressure of 780 mmHg and a final pressure of 1 atm.
v2= 102 mL

Imagine a balloon filled with helium on a cold winter day. While you are in the shop, the balloon is normal. As you step outside the balloon begins to shrivel up. This happens because of the temp. of the helium in the balloon deceases and becomes less dense, because the helium particles lose energy and become more concentrated, decreasing the volume. But when you put the balloon in a warm area, it goes back to its original size.
Charles's Law
300
Which law states that the volume of a fixed amount of gas is directly proportional to its kelvin temperature at a consistent pressure.
Charles's Law
300
What is the formula for Boyle's Law?
P1V1=P2V2
300
What is constant in Gay-Lussac's Law? (Gas,Pressure, Temperature, Volume?)
The amount of gas and the volume.
300
A dry gas has a pressure of 38.4kPa at 72.5°C. What will be the temperature of this gas at 80 kPa?
T2= 719.79k
300
Car tires explode more during hot summer months because the pressure of the gas inside the tire increases with increasing temperature - sometimes beyond the elastic capabilities of the tire.
Gay- Lussac's Law
400
Which law relates pressure, temperature, and volume in a single statement.
The Combined Gas Law
400
What is the formula for Gay-Lussac's Law?
P1 / T1 = P2 / T2
400
What is constant in the Combine Law? (Gas, Pressure, Temperature, Volume?)
The amount of gas.
400
Fine the initial volume of the initial pressure is 74.0 kPa and the initial temperature is 55°C. The final volume is 153 mL, the final pressure is 745 mmHg and the final temperature is 19°C.
V1= 230.62 mL

Weather balloons are launched daily from weather stations across the country. The balloon begins at the earth at a certain P, T, and V and upon its accent all three of these variables change in response to the surroundings. Cloud formation, refrigerators and air conditioners are more examples.
Combine Gas Law
