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

Rate this question:

• 7.

### A gas expands from a volume 2.0 L at 36oC to a volume of 2.5 L, what is the final temperature, if the pressure is constant?

• A.

386 K ( which equals 113.25 Celsius)

• B.

247.2 K (which equals -25.8 C)

• C.

61.8 K (which equals -211.2 C)

A. 386 K ( which equals 113.25 Celsius)
Explanation
Make sure you change to Kelvin!! (add 273) or you will get the WRONG answer!!

Rate this question:

• 8.

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

• A.

Increase

• B.

Decrease

• C.

Increase a little, then decrease.

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

Rate this question:

• 9.

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

• A.

Gases are compressible because of the space between particles.

• B.

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

• C.

The gases are NOT fluid

A. Gases are compressible because of the space between particles.
Explanation
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.

### Which of the following describes the relationship between P and V?

• A.

Directly proportional

• B.

Inversely proportional

• C.

Unrelated

B. Inversely proportional
Explanation
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.

### Boyle's Law expresses the relationship between

pressure and volume, p and v, volume and pressure, v and p
Explanation
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.

Rate this question:

• 12.

### T1/P1 = T2/P2 is Charles's Law

• A.

True

• B.

False

B. 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.
