Measuring Volume Through Water Displacement Techniques

The video tutorial explains how to measure the volume of a regularly shaped object, like a glass pebble, using the water displacement method. It highlights the limitations of using a ruler for curved surfaces and demonstrates how to use a graduated cylinder to measure the volume change when the pebble is submerged in water. The tutorial also clarifies the difference between milliliters and cubic centimeters, emphasizing that while milliliters are used for fluids, cubic centimeters are used for solids. The pebble's volume is calculated as two cubic centimeters, illustrating the concept of volume measurement for solid objects.

Why can't a ruler be used to measure the volume of the glass pebble?

• The ruler is not accurate enough.

• The pebble is transparent.

• The pebble has a curved surface.

• The pebble is too small.

What is the initial volume of water in the graduated cylinder before adding the pebble?

• 45 milliliters

• 40 milliliters

• 35 milliliters

• 30 milliliters

What is the purpose of measuring to the bottom of the meniscus?

• To prevent evaporation

• To measure the top of the liquid

• To avoid spilling

• To ensure accuracy

What happens to the water level when the pebble is added to the graduated cylinder?

• It evaporates.

• It increases.

• It stays the same.

• It decreases.

How much space does the pebble take up in the graduated cylinder?

• 1 milliliter

• 2 milliliters

• 3 milliliters

• 4 milliliters

Why are milliliters not used as the volume unit for the pebble?

• Milliliters are only for liquids.

• Milliliters are too large.

• Milliliters are not precise.

• Milliliters are outdated.

What is the equivalent of one milliliter in terms of solid volume?

• One cubic foot

• One cubic centimeter

• One cubic inch

• One cubic meter

What is the final volume of the pebble in cubic centimeters?

• 1 cubic centimeter

• 2 cubic centimeters

• 4 cubic centimeters

• 3 cubic centimeters

What is the relationship between milliliters and cubic centimeters?

• 1 milliliter equals 1 cubic meter

• 1 milliliter equals 1 cubic inch

• 1 milliliter equals 1 cubic foot

• 1 milliliter equals 1 cubic centimeter
