What is the principle of conservation of matter?

Back

The principle of conservation of matter states that matter cannot be created or destroyed in an isolated system; it can only change forms.

What is precipitation in the water cycle?

Back

Precipitation is the process by which water falls from the atmosphere to the Earth's surface in the form of rain, snow, sleet, or hail.

If a bag of groceries weighs 15 kg and contains 3 kg of fruit, 2 kg of cereal, and 5 kg of meat, how much does the soup weigh?

Back

The soup weighs 5 kg, as the total weight must equal 15 kg.

What happens to the mass of an object when it is crushed, such as an oreo cookie?

Back

The mass of the object remains the same; if an oreo cookie weighs 20 grams, its crumbs will also weigh 20 grams.

Front

What is the relationship between mass and volume in a substance?

Back

Mass is the amount of matter in a substance, while volume is the space that substance occupies; they are related by the density of the substance.

Front

What is the definition of density?

Back

Density is defined as mass per unit volume of a substance, typically expressed in grams per cubic centimeter (g/cm³).

Front

How does the water cycle demonstrate the conservation of matter?

Back

The water cycle demonstrates the conservation of matter as water continuously changes forms (liquid, vapor, solid) but the total amount of water remains constant.

Front

What is the significance of mass in chemical reactions?

Back

In chemical reactions, the mass of the reactants must equal the mass of the products, illustrating the conservation of matter.

Front

What occurs during the melting process of ice?

Back

During the melting process, ice changes from solid to liquid, but the mass of the water produced remains the same as the mass of the ice.
