Question

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

Answers

Answer
© An increase in pressure causes particles to move closer together, decreasing the volume.
• An increase in pressure causes particles to move farther apart, increasing the volume.
• An increase in pressure causes particles to move closer together, increasing the volume.
© An increase in pressure causes particles to move farther apart, decreasing the volume.

The relationship between the volume of a gas and its temperature (in Kelvin) at constant pressure is described by Charles's Law. According to Charles's Law, the volume of a gas is directly proportional to its absolute temperature (in Kelvin). This means that if the temperature of the gas increases, the volume will also increase, and if the temperature decreases, the volume will decrease, assuming pressure remains constant. Mathematically, this can be expressed as:

\[ V \propto T \]
or
\[ \frac{V_1}{T_1} = \frac{V_2}{T_2} \]

where \( V \) is the volume and \( T \) is the temperature in Kelvin.

The correct statement is:

**"An increase in pressure causes particles to move closer together, decreasing the volume."**

This reflects the behavior of gases under the principles of gas laws, particularly Boyle's Law, which states that at constant temperature, the volume of a gas is inversely proportional to its pressure. Therefore, when pressure increases, the volume must decrease as the gas particles are pushed closer together.
