6th-8th NGSS Review Part 1

Front

What happens to kinetic energy as the mass of an object increases?

Back

Kinetic energy increases.

Front

What happens to kinetic energy as the speed of an object increases?

Back

Kinetic energy increases.

Front

What does the subscript in H2O represent?

Back

It represents two atoms of Hydrogen.

Front

What is the role of evaporation in the water cycle?

Back

Evaporation turns liquid water into vapor, which rises into the atmosphere.

Front

What type of heat transfer is demonstrated by heat lamps keeping baby chickens warm?

Back

Radiation.

Front

Define kinetic energy.

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

Explain the process of evaporation.

Back

Evaporation is the process where liquid water turns into water vapor due to heat.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through fluid movement.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water through evaporation, condensation, and precipitation.
