Question & Answer
Choose the Best Answer
Increased temperature and decreased pressure lead to enhanced molecular translation and reduced intermolecular forces.
Decreased temperature and increased pressure result in strong molecular vibrations but limit translational motion.
Constant temperature and pressure maintain the same level of molecular rotation without affecting the state.
Increased molecular mass and potential energy contribute to a slower transition between states.
Understanding the Answer
Let's break down why this is correct
When the temperature rises, each molecule gets more kinetic energy, so it moves faster and more often. Other options are incorrect because Cooling the liquid actually reduces energy, so molecules vibrate less, not more; Keeping temperature and pressure fixed does not stop a liquid from turning into gas.

Definition
States of Matter refer to the physical forms substances can exist in, such as solid, liquid, and gas. Liquids are incompressible due to closely packed molecules, while gases are compressible since their molecules are far apart. Understanding the differences in molecular arrangement helps explain properties like compressibility and density.
