PhySci B - Unit 1 Test Review

Front

What is the relationship between pressure and volume in gases?

Back

Inverse relationship: As pressure increases, volume decreases, and vice versa.

Front

What happens to a substance when it gains energy?

Back

The substance's particles move faster, leading to a change in state or temperature.

Front

How do particle speeds change over time in a heating substance?

Back

Particles move faster as the substance gains energy.

Front

What is the formula for calculating pressure in a gas?

Back

Pressure (P) = Force (F) / Area (A) - This shows how pressure is related to force applied over an area.

Front

What is the volume of a gas at a pressure of 60 if the volume is inversely proportional to pressure?

Back

24 - This is based on the inverse relationship between pressure and volume.

Front

Describe the state change from liquid to solid.

Back

Before: Molecules move around each other (liquid), After: Molecules move in place (solid).

Front

What is kinetic energy in the context of particle motion?

Back

Kinetic energy is the energy of motion; as temperature increases, kinetic energy of particles increases.

Front

What is the definition of temperature in relation to particle motion?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What happens to gas volume when temperature increases at constant pressure?

Back

The volume increases (Charles's Law: V1/T1 = V2/T2).

Front

What is the definition of pressure in gases?

Back

Pressure is the force exerted by gas particles colliding with the walls of their container.
