Density and Beverage Composition

In this video, Mike Doy introduces the concept of density, defined as mass over volume. He demonstrates this using an aquarium filled with water and two cans of Pepsi: regular and Diet. The regular Pepsi sinks while the Diet Pepsi floats, illustrating the difference in density. The video explains that the regular Pepsi has more mass due to its sugar content, while Diet Pepsi uses aspartame, which is lighter. The video concludes with a visual comparison of sugar and aspartame quantities, emphasizing the impact of sugar on density.

What is the primary focus of the video tutorial?

• The concept of density

• The process of making Pepsi

• The history of Pepsi

• The nutritional value of beverages

What is the formula for calculating density?

• d = m / v

• d = m * v

• d = v - m

• d = v / m

Why does the regular Pepsi can sink in water?

• It has a higher density than water

• It has a lower density than water

• It is lighter than Diet Pepsi

• It is made of a different material

What is the density of Diet Pepsi as calculated in the video?

• 1.1 g/cm³

• 1.0 g/cm³

• 1.2 g/cm³

• 0.9 g/cm³

How does the density of an object affect its ability to float in water?

• Objects with lower density than water sink

• Objects with higher density than water float

• Objects with any density can float

• Objects with density equal to water float

What is the approximate mass of the Diet Pepsi can as measured in the video?

• 385 g

• 375 g

• 365 g

• 355 g

What ingredient in regular Pepsi contributes to its higher mass?

• Sugar

• Aspartame

• Carbon dioxide

How much sugar is in a regular Pepsi can according to the video?

• 20 g

• 30 g
