What two types of measurements make up DENSITY?

Back

Density is defined as mass divided by volume. Therefore, the two types of measurements that make up density are mass and volume.

Front

What makes objects visible?

Back

Objects are visible due to the reflected light from the object. When light hits an object, some of it is reflected back to our eyes, allowing us to see the object.

Front

If two objects have the same volume but different masses, which object will be more dense?

Back

The object with more mass will be more dense. Density is calculated as mass divided by volume, so a greater mass with the same volume results in higher density.

Front

Calculate the density of a rock with a mass of 14g and a volume of 2cm³.

Back

Density = Mass/Volume = 14g/2cm³ = 7 g/cm³.

What happens to the speed of gas particles when the temperature increases?

Back

When the temperature increases, gas particles move faster, bounce off walls more frequently, and create a bigger force on the walls.

Front

Define mass in the context of physics.

Back

Mass is a measure of the amount of matter in an object, typically measured in grams or kilograms.

Front

Define volume in the context of physics.

Back

Volume is the amount of space that an object occupies, typically measured in cubic centimeters (cm³) or liters.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

Explain the relationship between mass, volume, and density.

Back

Density is a property that relates mass and volume. If mass increases while volume remains constant, density increases. Conversely, if volume increases while mass remains constant, density decreases.

Front

What is the unit of measurement for density in the metric system?

Back

The unit of measurement for density in the metric system is grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
