Module 2.1 Physical Properties Review

Front

What is mass?

Back

Mass is the amount of matter in an object, typically measured in grams or kilograms. It does not change regardless of location.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity. It changes based on the gravitational pull of the celestial body.

Front

How does gravity affect objects in motion?

Back

Gravity pulls objects toward the center of a mass, such as Earth, affecting their motion and direction.

Front

What is solubility?

Back

Solubility is the ability of a substance to dissolve in a solvent, such as water, at a given temperature and pressure.

Front

What is the difference between soluble and insoluble substances?

Back

Soluble substances can dissolve in a solvent, while insoluble substances cannot.

Front

What is the principle of buoyancy?

Back

Buoyancy is the upward force exerted by a fluid that opposes the weight of an object immersed in it.

Front

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

How does temperature affect solubility?

Back

Generally, as temperature increases, the solubility of solids in liquids increases, while the solubility of gases decreases.

Front

What is the role of gravity in the water cycle?

Back

Gravity pulls water down from clouds as precipitation and helps it flow into rivers, lakes, and oceans.

Front

What is the formula for calculating weight?

Back

Weight (W) = Mass (m) × Gravitational acceleration (g). On Earth, g is approximately 9.81 m/s².
