Freezing Melting and Evaporation

In which state of matter are particles usually farthest apart and move the fastest?

• Solid

• Liquid

• Gas

• Plasma

What is the process called when a liquid changes into a gas?

• Condensation

• Evaporation

• Sublimation

• Precipitation

What is the term for the temperature at which a solid turns into a liquid?

• Melting point

• Boiling point

• Freezing point

• Sublimation point

What is the difference between boiling and evaporation?

• Boiling occurs only at the surface of the liquid, while evaporation occurs throughout the liquid.

• Boiling creates gas bubbles throughout the liquid, while evaporation occurs at the surface of the liquid, releasing gas into the air.

• Boiling happens at any temperature, while evaporation only happens at high temperatures.

• Boiling is a slow process, while evaporation is a rapid process.

What factors can increase the rate of evaporation?

• Lower temperature and increased humidity

• Higher temperature, increased surface area, and lower humidity

• Decreased surface area and higher humidity

• Constant temperature and low wind speed

What happens to the temperature of a substance during boiling?

• The temperature increases continuously until all the liquid evaporates.

• The temperature remains constant until the entire liquid has turned into gas.

• The temperature decreases as the liquid boils.

• The temperature fluctuates randomly during the boiling process.

In which container will water evaporate the fastest: a glass, a teacup, a small bowl, or a dinner plate?

• A glass

• A teacup

• A small bowl

• A dinner plate

What is the process called when a solid changes directly into a gas?

• Evaporation

• Condensation

• Sublimation

• Melting

What is the process called when a gas changes into a solid?

• Sublimation

• Condensation

• Deposition

• Evaporation

What is the main difference between a physical change and a chemical change?

• A physical change alters the form of a substance but not its chemical composition, while a chemical change results in the formation of new substances.

• A physical change involves a change in temperature, while a chemical change does not.

• A physical change can be reversed, while a chemical change cannot be reversed.

• A physical change affects the chemical properties of a substance, while a chemical change does not.
