Which of the following statements is/are correct? 1. if the intermolecular forces in a liquid decrease, the normal boiling point of the liquid decreases. 2. if the temperature of a liquid increases, the equilibrium vapor pressure increases. 3. if the surface area of a liquid increases, the equilibrium vapor pressure of the liquid increases.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
