7. 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.
