W&W Investigation 3 Convection

Front

What is the formula for calculating density?

Back

Density = Mass / Volume

Front

What happens to the motion of particles in a fluid when thermal energy is added?

Back

The motion of the particles speeds up.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).

Front

How does the density of a fluid affect its ability to rise or sink?

Back

Fluids with lower density will rise above fluids with higher density.

Front

What is the relationship between temperature and the kinetic energy of particles in a fluid?

Back

As temperature increases, the kinetic energy of the particles increases.

Front

What occurs when air above a warm surface, like sand, becomes less dense?

Back

The less dense air rises, creating convection currents.

Front

What is the significance of particle collisions in a fluid when thermal energy is added?

Back

When thermal energy is added, there are more collisions among the particles.

Front

How does the temperature of air above water compare to air above sand on a warm day?

Back

The temperature of the air above sand is typically warmer than the air above water.

Front

What is the effect of opening windows in a warm room?

Back

Opening windows allows cooler outside air to enter, lowering the room's temperature.
