When you exercise, your muscles need more energy. What happens to your heartbeat when you exercise?
-
It goes up
-
It goes down
-
It stays the same
Correct Answer
A. It goes upExplanation
During exercise, your muscles require more oxygen and nutrients to produce energy. To meet this increased demand, your heart pumps more blood to deliver oxygen and nutrients to the muscles. As a result, the heart rate increases to supply the necessary oxygenated blood to the working muscles. This increased heart rate helps to maintain the body's energy needs during exercise.Rate this question:

What is the process for turning a liquid into a gas? (Water into water vapor)
-
Boiling
-
Melting
-
Freezing
-
Condensation
Correct Answer
A. BoilingExplanation
Boiling is the process of turning a liquid into a gas, specifically in the case of water turning into water vapor. During boiling, heat is applied to the liquid, causing the molecules to gain energy and move faster. As a result, the liquid reaches its boiling point, where the vapor pressure of the liquid equals the atmospheric pressure. This causes bubbles to form and rise to the surface, converting the liquid into a gas state.Rate this question:

Which of these materials can dissolve in water?
-
Sand
-
Sugar
-
Lentils
-
Oil
Correct Answer
A. SugarExplanation
Sugar can dissolve in water because it is a soluble substance. When sugar is added to water, the water molecules surround the sugar molecules and pull them apart, causing the sugar to dissolve. This process is known as dissolution. The resulting solution is a homogeneous mixture where the sugar molecules are evenly distributed throughout the water.Rate this question:
-
- 13.
Which of these materials can't dissolve into the water?
-
Salt
-
Coffee
-
Sand
-
Sugar
Correct Answer
A. SandExplanation
Sand cannot dissolve into water because it is composed of large particles that do not have the ability to form bonds with water molecules. Unlike salt, coffee, and sugar, which are soluble in water and can dissolve, sand remains as separate particles when mixed with water, resulting in a mixture rather than a solution.Rate this question:

What happens to sugar when it is dissolved in water?
-
It changes into salt.
-
It becomes invisible but remains present in the solution.
-
It disappears permanently.
-
It turns into water.
Correct Answer
A. It becomes invisible but remains present in the solution.Explanation
When sugar is dissolved in water, it breaks down into smaller particles that are too small to see, making it seem like it has disappeared. However, the sugar is still present in the water; it has just mixed thoroughly to form a solution. This is why the water tastes sweet. The sugar doesn't change its chemical composition into something else like salt or water; it simply disperses throughout the water.Rate this question:

Which one of these changes is irreversible?
-
Melting wax
-
Burning a log in a fire
-
Melting an ice cube
-
None of the above
Correct Answer
A. Burning a log in a fireExplanation
Burning a log in a fire is an irreversible change because it involves a chemical reaction called combustion, which breaks down the complex molecules in the log into simpler molecules, releasing heat and light in the process. Once the log is burned, it cannot be restored to its original state as the chemical composition of the log has been permanently altered. Melting wax and melting an ice cube are physical changes that can be reversed by cooling or solidifying the substances. Therefore, burning a log in a fire is the only option that represents an irreversible change.Rate this question:
