Semester 1 review

Front

How do the particles in a solid move compared to the particles in a liquid?

Back

The particles in a solid vibrate in place, while the particles in a liquid move past each other.

Front

What happens to the particles in a gas when the temperature is increased?

Back

The particles speed up and spread farther apart.

Front

How do particles move in a solid, liquid, and gas?

Back

In a solid, particles vibrate in place; in a liquid, they move past each other; in a gas, they move quickly and spread apart.

Front

In which state of matter are the particles closest together?

Back

Solid

Front

When a solid melts into a liquid, what happens to the movement of the particles?

Back

The particles begin to move past each other more freely.

Front

Why do gases expand to fill the space of their container?

Back

The particles in a gas move fast and spread out to fill the space.

Front

How does the speed of the particles in a liquid change when it is heated?

Back

The particles move faster and spread farther apart.

Front

What is the difference between the particle movement in a gas and the particle movement in a liquid?

Back

Particles in a gas are spread far apart and move quickly, while particles in a liquid are closer together and move past each other.

Front

How does heat move through a boiling pot of water?

Back

Heat moves from the water’s surface to the bottom of the pot, and from there, it spreads throughout the water.

Front

How does convection cause the water in a pot to heat up evenly?

Back

The hot water rises, while cooler water sinks, creating a circular motion that helps heat spread evenly throughout the pot.
