Which statement correctly describes the relationship between the volume of a gas and its temperature, in Kelvin, assuming pressure is held constant?(1 point)
The relationship is inversely proportional; as temperature increases, volume increases in the same way.
The relationship is directly proportional; as temperature increases, volume increases in the same way.
The relationship is directly proportional; as temperature increases, volume decreases in the same way.
The relationship is inversely proportional; as temperature increases, volume decreases in the same way.
2.Which statement explains the molecular changes that occur in an enclosed gas as the pressure increases and the temperature is held constant?(1 point)
An increase in pressure causes particles to move closer together, increasing the volume.
An increase in pressure causes particles to move closer together, decreasing the volume.
An increase in pressure causes particles to move farther apart, decreasing the volume.
An increase in pressure causes particles to move farther apart, increasing the volume.
3.The ideal gas law is represented by PV=nRT. As volume is held constant and the temperature increases, how would the pressure be expected to change?(1 point)
It would decrease.
It would become zero.
It would remain constant.
It would increase.
