LBC Ch10 (without weather), density temp charles's law

Identify the equipment shown here:

• Flux capacitors

• Buckets

• The rainbow experiment

• Graduated cylinders

Identify the equipment shown here:

• Cup

• Flask

• Beaker

• My friend posted in TikTok that I should choose this one, but it doesn't seem right.

What is measured with a graduated cylinder?

• Passage of time

• Distance from one thing to another

• Weight of an object

• Volume of liquid

What should you do if you break glass in the lab?

• Tell the teacher.
• Sweep up the glass.
• Pick up the glass with your hands.
• Ignore it; the teacher will clean it up when she sees it later.

What two types of measurements are needed to calculate DENSITY?

• Mass and Volume

• Temperature and Mass

• Grams and Centimeters

• Volume and Weight

Answer explanation

Density = Mass / Volume

If an object has a density of .6 g/mL and you put it into water, will it sink or float?

• sink

• float

Answer explanation

The density of water is 1.0 g/ml. Anything with a density of less than 1.0 will float in water. If you forgot if > or < 1.0 g/ml floats, consider extreme examples. 0.01 g/ml is very low density and will float. 100 g/ml is very high density and will sink.

If an object has a density of 3.6 g/mL and you put it into water, will it sink or float?

• sink

• float

Answer explanation

The density of water is 1.0 g/ml. Anything with a density of less than 1.0 will float in water. If you forgot if > or < 1.0 g/ml floats, consider extreme examples. 0.01 g/ml is very low density and will float. 100 g/ml is very high density and will sink.

Frank has an eraser. It has a mass of 4g, and a volume of 2cm³. What is its density?

• 8 g/cm³

• 2 g/cm³

• 1/2 g/cm³

• 24 g/cm³

Answer explanation

Density = mass / volume

What units are used to measure mass?

• g
• cm³
• g/cm³
• cm³/g

What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume

Answer explanation
