What is the relationship between pressure and temperature at constant volume?

• Pressure is inversely proportional to temperature (in Kelvin).

• Pressure is directly proportional to temperature (in Kelvin).

• Pressure is independent of temperature at constant volume.

• Pressure is proportional to the square of temperature (in Kelvin).

What happens to solids when they are heated?

• The particles vibrate more vigorously, causing the solid to expand and potentially melt.

• The solid becomes a liquid immediately without any change in structure.

• The solid contracts and becomes denser as it heats up.

• The particles stop moving completely, causing the solid to harden.

How does sweating help regulate body temperature?

• It increases blood flow to the skin, warming the body.

• As sweat evaporates, it removes heat from the body, cooling it.

• It causes the body to retain heat, preventing overheating.

• It stimulates the production of more sweat glands.

What is the process of a liquid turning into a gas called?

• Condensation

• Vaporization

• Evaporation

• Precipitation

How does evaporation cause cooling?

• As faster-moving particles escape, the remaining particles have lower average kinetic energy, decreasing the temperature.

• Evaporation absorbs heat from the surroundings, increasing the temperature.

• Evaporation occurs only at high temperatures, which does not affect cooling.

• The process of evaporation releases energy, causing the temperature to rise.

What practical application uses evaporation to cool?

• Refrigerators use a refrigerant that evaporates inside coils, absorbing thermal energy from food.

• Air conditioners use a fan to blow air over ice, cooling the room.

• Heat pumps transfer heat from the outside air to warm a building.

• Dehumidifiers use evaporation to remove moisture from the air.

How do particles behave in gases?

• They move rapidly in straight lines and collide with each other and the walls of their container.

• They remain stationary and do not move at all.

• They move slowly and stick together in clusters.

• They vibrate in place without moving freely.

What is internal energy?

• The total of a material's kinetic and potential energy.

• The energy stored in chemical bonds.

• The energy associated with the motion of electrons.

• The energy required to change the temperature of a substance.
