Why do paper towels absorb water?

• A) Paper towels absorb water because they have tiny holes and spaces that catch water molecules.

• B) Paper towels absorb water because they are made of a material that naturally attracts water.

• C) Paper towels absorb water because they release chemicals that make water molecules stick to them.

• D) Paper towels absorb water because they have a smooth surface that repels water molecules.

How does the use of fire in sky lanterns contribute to their floating in the air?

• A) By providing light to illuminate the lantern, making it visible in the dark sky.

• B) By heating the air inside the lantern, causing it to become less dense and creating a buoyant force that lifts the lantern upward.

• C) By producing smoke that adds to the overall weight of the lantern, aiding in its descent back to the ground.

• D) By melting the paper or fabric of the lantern, causing it to disintegrate and fall to the ground.

Which statement is most accurate about Kinetic Molecular Theory?

• A) According to the theory, gas particles move randomly and collide with each other and the walls of the container, resulting in pressure exerted by the gas.

• B) The theory suggests that as the temperature of a gas decreases, the average speed of its particles decreases as well.

• C) Gas particles are attracted to each other, forming solid structures, as proposed by the theory.

• D) The theory states that gas particles have a significant volume compared to the volume of the container they occupy.

Imagine you have a balloon filled with air, and you place it outside under the sun for a few hours. What do you think will happen to the balloon, and why?

• A) The balloon will get smaller because sunlight makes things shrink.

• B) The balloon will stay the same size because sunlight doesn't affect balloons.

• C) The balloon will get bigger because sunlight heats up the air inside, causing it to expand.

• D) The balloon will pop because sunlight makes things explode.

Considering the viscosity of water, oil, gasoline, and honey, which statement is most accurate?

• A) Water flows faster than oil, gasoline, and honey because it's thicker.

• B) Oil and gasoline flow easily, so they have low viscosity compared to water and honey.

• C) Gasoline pours easily, making it less viscous than water, oil, and honey.

• D) Honey flows very slowly and offers the most resistance to motion compared to water, oil, and gasoline.
