Chemistry Semester 1 Review Conroy

Front

What is density?

Back

Density is the comparison of mass and volume.

Front

How does temperature affect the volume of a gas?

Back

According to Charles's Law, the volume of a gas increases with an increase in temperature, provided the pressure remains constant.

Front

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction.

Front

Which glassware is used to measure liquid volume most accurately?

Back

Graduated Cylinder is used to measure liquid volume most accurately.

Front

What phase of matter is represented when particles are closely packed and vibrate in place?

Back

Solid.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What happens to the volume of a gas when the temperature is decreased?

Back

The volume of a gas decreases when the temperature is decreased, according to Charles's Law.

Front

What is the significance of the graduated cylinder in experiments?

Back

The graduated cylinder provides precise measurements of liquid volume.

Front

How many particles are in a system if the Law of Conservation of Mass is followed and there are 11 particles in total?

Back

There should be 11 particles in the system.

Front

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

Back

Density is determined by the ratio of mass to volume.
