Inv. 4 Chemical Interactions I-check

Front

What is the effect of applying ice to a bolt and nut that won't come off easily?

Back

Applying ice to the bolt causes it to contract, making it easier to loosen the nut.

Front

What is the term for the area that exists between particles in a substance?

Back

Space.

Front

What is the phenomenon called when a bottle of pop caves in after being taken outside in cold weather?

Back

Contraction.

Front

What happens to the space between particles in a substance when it is heated?

Back

The space between particles increases.

Front

True or False: The cold water mark in a bottle should be lower than the room temperature mark. Why?

Back

True, because the cold water contracts, taking up less space than water at room temperature.

Front

Define contraction in the context of particle behavior.

Back

Contraction is the process where particles come closer together, usually due to a decrease in temperature.

Front

What happens to the kinetic energy of particles when a substance is heated?

Back

The kinetic energy of the particles increases, causing them to move faster and spread apart.

Front

Explain how temperature affects the state of matter.

Back

Increasing temperature can change a solid to a liquid (melting) or a liquid to a gas (evaporation), while decreasing temperature can change a gas to a liquid (condensation) or a liquid to a solid (freezing).

Front

What is the relationship between temperature and particle movement?

Back

As temperature increases, particle movement becomes more vigorous; as temperature decreases, particle movement slows down.

Front

What is the significance of space in a syringe filled with liquid?

Back

The space in a syringe allows for the movement and compression of the liquid, which is essential for its function.
