Explanation

Make sure you change to Kelvin!! (add 273) or you will get the WRONG answer!!
V1/T1 = V2/T2 Charles' law

2. If the air inside a balloon is heated, the volume will:

Increase

Decrease

Increase a little, then decrease.

Temperature and Volume are directly related (Charles' law): When temperature is increased, volume will also increase.

Explanation

Temperature and Volume are directly related (Charles' law): When temperature is increased, volume will also increase.

3. T1/P1 = T2/P2 is Charles's Law

True

False

The given statement, T1/P1 = T2/P2, is not Charles's Law. Charles's Law states that the volume of a gas is directly proportional to its temperature, assuming constant pressure. The correct equation for Charles's Law is V1/T1 = V2/T2. Therefore, the answer is false.

Explanation

The given statement, T1/P1 = T2/P2, is not Charles's Law. Charles's Law states that the volume of a gas is directly proportional to its temperature, assuming constant pressure. The correct equation for Charles's Law is V1/T1 = V2/T2. Therefore, the answer is false.

4. A balloon occupies a volume of 2.0 L at 40^oC. How much volume will it occupy at 30^oC?

1.5 L

1.94 L

1.6 L

Make sure you change to Kelvin!! (add 273) or you will get the WRONG answer!!

Explanation

Make sure you change to Kelvin!! (add 273) or you will get the WRONG answer!!

5. What is the final pressure in a vessel when the volume is changed from 1.3 L to a volume of 1.55 L at constant temperature? (Initial pressure is 1.5 atm).

1.25 L

1.65 L

1.49 L

The units will be the SAME on both sides of the equation.

Explanation

The units will be the SAME on both sides of the equation.

6. A balloon occupies 3.2 L at 37^oC. How much will it occupy at 42^oC?

3.15 L

3.25 L

312,480 L

Make sure you change to Kelvin!! (add 273) or you will get the WRONG answer!! V1/T1 = V2/T2 Charles' law

Explanation

Make sure you change to Kelvin!! (add 273) or you will get the WRONG answer!! V1/T1 = V2/T2 Charles' law

7. Which of the following describes the relationship between P and V?

Directly proportional

Inversely proportional

Unrelated

The relationship between P and V is inversely proportional. This means that as one variable increases, the other variable decreases, and vice versa. In other words, when P increases, V decreases, and when P decreases, V increases. There is a consistent and predictable relationship between the two variables, where they vary in opposite directions. This can be represented by the equation P = k/V, where k is a constant.

8. What is the final pressure in a balloon when the volume is changed from 1.5 L to a volume of 2.5L at constant temperature? (Initial pressure is 1.1 atm).

.66 atm

.66 kPa

4.125 atm

The units will be the SAME on both sides of the equation.

Explanation

The units will be the SAME on both sides of the equation.

9. According to the Kinetic Theory of Gases which is true.

Gases are compressible because of the space between particles.

The distance between molecules in ideal gases is closer than in liquids or solids.

The gases are NOT fluid

According to the Kinetic Theory of Gases, gases are compressible because of the space between particles. This is because gas particles are in constant random motion and have a lot of empty space between them. When pressure is applied to a gas, the particles can be pushed closer together, reducing the volume of the gas. In contrast, in liquids and solids, the particles are much closer together and have less empty space between them, making them less compressible. Therefore, the statement that gases are compressible because of the space between particles is true based on the Kinetic Theory of Gases.

10. Boyle's Law expresses the relationship between

Boyle's Law states that there is an inverse relationship between the pressure and volume of a gas at constant temperature. This means that as the pressure increases, the volume decreases, and vice versa. The variables p and v represent pressure and volume respectively, and the answer correctly states that Boyle's Law expresses the relationship between these two variables. The second part of the answer simply repeats the same information in a different order, stating that Boyle's Law also relates volume and pressure, represented by the variables v and p.
