States of Matter and Kinetic Energy

What occurs when a substance loses thermal energy?

• The particles move faster and spread apart.

• The particles move slower and may come closer together.

• The substance changes color and becomes lighter.

• The substance evaporates and turns into gas.

What is kinetic energy?

• The energy of motion; the faster an object moves, the more kinetic energy it has.

• The energy stored in an object due to its position.

• The energy released during a chemical reaction.

• The energy associated with the temperature of an object.

What is the process of freezing?

• The change from liquid to solid when a substance loses thermal energy.

• The process of heating a solid to become a liquid.

• The transformation of gas into a liquid when cooled.

• The conversion of a solid directly into a gas without becoming liquid.

What occurs when a substance gains thermal energy?

• The particles move faster and may move further apart.

• The substance becomes colder and denser.

• The particles slow down and come closer together.

• The substance changes color and becomes opaque.

How does temperature relate to kinetic energy?

• Higher temperature means higher kinetic energy as particles move faster.

• Temperature has no effect on kinetic energy.

• Higher temperature means lower kinetic energy as particles move slower.

• Kinetic energy is independent of temperature.

What is thermal energy?

• The energy produced by burning fossil fuels.

• The energy stored in chemical bonds of molecules.

• The total energy of all the particles in a substance, related to temperature.

• The energy associated with the motion of an object.

What happens to particles in a gas?

• Particles are tightly packed and vibrate in place.

• Particles are far apart and move freely, filling the space available.

• Particles are arranged in a fixed structure and do not move.

• Particles are in a liquid state, flowing but not filling the space.

What happens to air in a hot air balloon when heated?

• The air contracts, causing the balloon to sink.

• The air expands, causing the balloon to rise.

• The air remains the same, keeping the balloon stable.

• The air cools down, causing the balloon to deflate.

What is evaporation?

• The process of a liquid turning into a gas when it gains enough thermal energy.

• The process of a gas turning into a liquid when it loses thermal energy.

• The process of a solid turning into a liquid when it gains thermal energy.

• The process of a liquid turning into a solid when it loses thermal energy.

What is condensation?

• The process of a gas turning into a liquid when it loses thermal energy.

• The process of a liquid turning into a gas when it gains thermal energy.

• The process of a solid turning into a liquid when it gains thermal energy.

• The process of a gas turning into a solid when it loses thermal energy.
