What law states that energy cannot be created or destroyed, only transformed?

• Law of conservation of mass

• Law of conservation of energy

• Law of universal gravitation

• Law of thermodynamics

What type of wave is characterized by the movement of the medium at right angles to the direction of the wave?

• Sound wave

• Longitudinal wave

• Transverse wave

• Surface wave

What is the kinetic theory of matter?

• Theory that matter is made up of tiny particles in random motion

• Theory that energy can neither be created nor destroyed

• Theory that gravity affects all objects in motion

• Theory that matter can change states under pressure

According to Archimedes' principle, what happens when a body is immersed in a fluid?

• The body experiences a buoyant force equal to the weight of the fluid displaced

• The body automatically sinks regardless of its density

• The body expands in volume

• The body loses all gravitational force

What principle states that pressure applied to a confined fluid increases the pressure throughout by the same amount?

• Charles' law

• Pascal's principle

• Boyle's law

• Bernoulli's principle

How does Boyle's law relate pressure and volume of a gas?

• Pressure of a gas increases as the volume increases

• Pressure of a gas decreases as the volume increases

• Pressure of a gas is independent of the volume

• Pressure of a gas decreases as the volume decreases

What is the effect of temperature on the viscosity of a liquid?

• Viscosity increases as temperature increases

• Viscosity decreases as temperature increases

• Viscosity is not affected by temperature

• Viscosity initially decreases then increases as temperature increases

What is used to identify elements and compounds?

• Tyndall effect

• Solution

• Distillation

• Chemical property
