Chemistry 102 Summative Review

Front

What is density?

Back

Density is the mass of a substance divided by its volume, typically expressed in grams per milliliter (g/ml) or grams per cubic centimeter (g/cm³).

Front

How do you calculate the density of an object?

Back

Density = Mass / Volume.

Front

What happens to objects with a density less than water?

Back

Objects with a density less than water float.

Front

What happens to objects with a density greater than water?

Back

Objects with a density greater than water sink.

Front

If an object has a mass of 120 g and a density of 0.6 g/cm³, what is its volume?

Back

Volume = Mass / Density = 120 g / 0.6 g/cm³ = 200 cm³.

Front

What is the relationship between temperature and gas pressure?

Back

As the temperature of a gas increases, the pressure also increases, assuming volume remains constant.

Front

What is the formula for calculating pressure?

Back

Pressure = Force / Area.

Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, determined by the object's density relative to the fluid's density.

Front

What is the principle of Archimedes?

Back

The principle of Archimedes states that an object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by the object.

Front

What is the unit of density?

Back

The unit of density is typically grams per milliliter (g/ml) or grams per cubic centimeter (g/cm³).
