Glass Analysis Lab

What is the purpose of comparing glass using liquids with different refractive indices?

• To measure the thickness of the glass

• To determine the strength of the glass

• To identify the color of the glass

• To compare the refractive indices of the glass to the liquids

Which liquid was suggested as the best option for this experiment?

• Baby oil

• Canola oil

• Glycerin

• Water

Where can glycerin, the preferred liquid for this experiment, be found?

• Pharmacy area of most retailers

• Only in specialized chemical stores

• In any food store

• Online only

What is the significance of using a spot plate in the lab for this experiment?

• To contain small amounts of liquids for submersion

• To hold different types of glass

• To heat the liquids

• To measure the volume of liquids

How can the experiment be conducted without a spot plate?

• Using large beakers only

• Using small glass or plastic containers

• It cannot be conducted without a spot plate

• Using paper cups

For the home experiment, how many types of liquids are students encouraged to use for submersion?

• At least one

• Exactly two

• At least two

• All available liquids

What happens when a piece of glass has a similar refractive index to the liquid it's submerged in?

• The glass becomes completely opaque

• The glass floats to the surface

• The glass changes color

• The glass becomes nearly invisible

What type of glass was found to be nearly invisible in glycerin due to matching refractive indices?

• Flint glass

• None of the above

• Soda-lime glass

• Borosilicate glass

What does the visibility of glass in a liquid indicate about their refractive indices?

• They are identical

• They are completely unrelated

• They are inversely proportional

• They are directly proportional

What was the outcome when borosilicate glass was submerged in glycerin?

• It became nearly invisible

• It changed color

• It floated on the surface

• It dissolved
