Front

What is an inference?

Back

An inference is a conclusion drawn from observations or evidence, rather than direct observation.

Front

What is a qualitative observation?

Back

A qualitative observation involves descriptions that do not include numerical measurements.

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

Front

How do you determine which liquid is the most dense?

Back

The most dense liquid is the one that has the highest mass per unit volume.

Front

What is the relationship between mass and density?

Back

Density is directly proportional to mass when volume is constant.
