Matter

Front

Why does a bag filled with air rise into the air when released from a container after heating?

Back

The air inside the bag is less dense than the air around it.

Front

What happens to the gas inside a bag when thermal energy is removed from the container?

Back

The gas will contract.

Front

What happens to the gas inside a bag when thermal energy is added to the container?

Back

The gas will expand.

Front

What is the relationship between temperature and the behavior of gas particles?

Back

As temperature increases, gas particles move faster and spread apart.

Front

What is density and how does it relate to buoyancy?

Back

Density is mass per unit volume; an object will float if it is less dense than the fluid it is in.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance.

Front

What is the principle of buoyancy?

Back

An object will float if the buoyant force is greater than or equal to its weight.

Front

What is the effect of pressure on gas volume according to Boyle's Law?

Back

As pressure increases, the volume of a gas decreases, and vice versa.
