Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

How does the mass of an assembled model compare to its individual parts?

Back

The mass of the assembled model equals the mass of all the individual parts combined.

Front

What happens to the mass of an object when it changes state, such as melting?

Back

The mass stays the same, even when the object changes state.

Front

What is the best method to weigh a large quantity of apples?

Back

Divide the apples into smaller sets and weigh each set separately for the most accurate measurement.

Front

If two objects have the same mass, what can we say about their weight?

Back

If two objects have the same mass, they also have the same weight under the same gravitational conditions.

Front

What is the principle of conservation of mass?

Back

The principle states that mass cannot be created or destroyed in a closed system; it can only change forms.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

How can you find the mass of an object using a balance scale?

Back

Place the object on one side of the balance and adjust weights on the other side until they are equal.

Front

What is a balance scale used for?

Back

A balance scale is used to compare the mass of two objects.

Front

What is the significance of measuring mass in kilograms?

Back

Kilograms are the standard unit of mass in the International System of Units (SI), making it easier to communicate measurements.
