Density Day 2

Front

What is the unit of measurement for mass?

Back

Grams (g) is the standard unit of measurement for mass in the metric system.

Front

What is density?

Back

Density is defined as the mass of a substance per unit volume, commonly expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).

Front

How is volume calculated using water displacement?

Back

Volume can be calculated by submerging an object in water and measuring the amount of water displaced, which equals the volume of the object.

Front

What happens to the density of most substances as temperature increases?

Back

Generally, the density of most substances decreases as temperature increases due to expansion.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is the relationship between mass and volume in determining density?

Back

Density is directly proportional to mass and inversely proportional to volume; as mass increases, density increases if volume remains constant.

Front

What is the significance of the unit 'g/mL' in density measurements?

Back

The unit 'g/mL' indicates that density is measured in grams per milliliter, which is commonly used for liquids.

Front

What is the difference between mass and weight?

Back

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

Front

How does temperature affect the amount of energy in a substance?

Back

As temperature increases, the amount of energy in a substance also increases, leading to greater molecular movement.

Front

What is the definition of volume?

Back

Volume is the amount of space an object occupies, measured in cubic units such as cubic centimeters (cm³) or liters (L).
