7th Grade Q2 BMA EXAM 2024-2025

Front

What happens to the temperature of an object when energy as heat is removed?

Back

The temperature of the object decreases.

Front

What is the relationship between the speed of light and the density of a substance?

Back

Light travels slower in denser substances because the molecules are closer together.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from potential energy to kinetic energy.

Front

What is evaporation?

Back

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

Front

What is the difference between a scientific investigation and a replication of an experiment?

Back

A scientific investigation is the process of conducting an experiment to explore a hypothesis, while replication is when another person repeats the same experiment to verify results.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object based on its position or state.

Front

How does heat transfer occur?

Back

Heat transfer occurs through conduction, convection, and radiation.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the effect of temperature on the state of matter?

Back

Increasing temperature can cause solids to melt into liquids and liquids to evaporate into gases.
