A)Which statement correctly describes the relationship between the volume of a gas and its temperature, in Kelvin, assuming pressure is held constant?(1 point)

Question

Responses

The relationship is directly proportional; as temperature increases, volume increases in the same way.

Answer 1

Here are the answers to your questions based on the principles of gas laws:

Question 1:
Correct Response: The relationship is directly proportional; as temperature increases, volume increases in the same way.
This describes Charles's Law, which states that at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin.

---

Question 2:
Correct Response: An increase in pressure causes particles to move closer together, decreasing the volume.
This describes the behavior of gases under pressure, as explained by Boyle's Law, which states that at constant temperature, the volume of a gas is inversely proportional to its pressure.

---

Question 3:
Correct Response: It would increase.
According to the ideal gas law (PV=nRT), if the volume is constant and the temperature increases, the pressure must increase as well.

---

Question 4:
Correct Response: V
According to Boyle's Law, when the pressure of a gas decreases while all other variables are held constant, the volume of the gas would increase.

---

Question 5:
Correct Response: the number of moles of each gas
While pressure, volume, and temperature are the same, the gases can differ in the number of moles, which could affect their mass and other properties.
