Question

Jaysen placed an unknown liquid into a beaker, and performed a series of changes to the temperature & pressure of the substance. Which statement correctly demonstrated how the particles changed? A. He decreased the temperature & the particles began moving slower; therefore, the liquid became a gas. B. He increased the pressure & the particles began moving slower; therefore, the liquid became a gas. C. He decreased the pressure & the particles began moving faster; therefore, the liquid became a solid. D. He increased the temperature & the particles began moving faster; therefore, the liquid became a gas.

Answer 1

The correct statement is D: increasing the temperature of a liquid leads to the liquid becoming a gas as the particles speed up due to increased kinetic energy.

Step-by-step explanation:

The correct choice that describes how Jaysen's experiment influenced the particles in the unknown liquid is: D.

He increased the temperature & the particles began moving faster; therefore, the liquid became a gas.

This choice aligns with our understanding of the states of matter and how the kinetic energy of particles influence them. Heat energy causes particles to move faster, resulting in an increase in entropy and the substance transitioning into a gaseous state. Conversely, a decrease in temperature slows down particle movement and can lead to the substance becoming a solid.

In terms of pressure, an increase generally encourages a substance to become more compact (turning gas into liquid or liquid into solid), while a decrease generally supports expansion (liquid to gas or solid to liquid). Therefore, the options relating to pressure are not correct.
