Understanding Solubility and Mass

What is the term used to describe a substance's ability to dissolve in a liquid?

• Volume

• Density

• Solubility

• Mass

Why is it difficult to separate sugar from lemonade once it has dissolved?

• Because sugar becomes a solid

• Because the physical properties of sugar change when it dissolves

• Because sugar changes its color

• Because sugar is heavier than water

Which of the following is an example of an insoluble substance?

• Coffee grounds

• Sand

• Sugar

• Salt

What is mass a measure of?

• The color of an object

• The ability of an object to float

• The amount of matter in an object

• The amount of space an object occupies

How does the mass of a bowling ball compare to that of a soccer ball with the same volume?

• The bowling ball has less mass

• The soccer ball has more mass

• They have the same mass

• The bowling ball has more mass

What factor, besides volume, affects the mass of an object?

• Temperature

• Density

• Shape

• Color

Which of the following objects would have the least mass?

• A balloon filled with air

• A bowling ball

• A balloon filled with water

• A beach ball filled with sand

What is the relationship between volume and mass?

• Mass is always greater than volume

• Volume is always greater than mass

• Mass depends on both volume and density

• Volume depends on mass only

Which of the following substances is soluble in water?

• Glass

• Salt

• Rocks

• Pepper

What is the key takeaway about mass from the video?

• Mass is unrelated to density

• Mass is influenced by both volume and density

• Mass is determined by volume alone

• Mass is only about how big an object is
