## When rock was placed in a graduated cylinder containing water What do you think will happen to the rock?

Explanation: The idea here si that the volume of the rock will be equal to the volume of water it displaces when added to the graduated cylinder. Now, in order to find the density of the rock, you must determine the mass of exactly one unit of volume the rock would occupy.

### What is the volume of the rock if the water level rises to the 120 mL mark?

If the graduated cylinder has 80ml and when you put the rock in, then it rises to 120ml, you subtract 120 ml- 80l. 120-80 equals 40. So the volume of the rock is 40ml.

**Which physical property of the rock is being measured using a graduated cylinder?**

The volume of a substance can be measured in volumetric glassware, such as the volumetric flask and the graduated cylinder. Density indicates how much of a substance occupies a specific volume at a defined temperature and pressure. The density of a substance can be used to define the substance.

**Why does the water volume in the graduated cylinder match the spheres volume?**

Why does the water volume in the graduated cylinder match the sphere’s volume? Each mL of water displaced into a graduated cylinder is equal to each cubic centimeter in the volume of the sphere.

## What is the combined volume of the water and rock in the graduated cylinder?

Explanation: The total volume (rock plus water) in the graduated cylinder is 34 mL. We know the volume of water in the cylinder was 20 mL. Therefore, the volume of the rock must be 14 mL. Because a milliliter is exactly the same volume as a cubic centimeter, the volume of the rock is 14 cm3.

### How does the density of the rock compare to the density of the water?

If an object such as a piece of wood floats on water it is less dense than water vs. if a rock sinks, it is more dense than water.

**How do you find the volume of a rock in a graduated cylinder?**

Example:

- Fill a graduated cylinder with 30 mL of water. 30 mL is the initial volume of the water.
- Carefully place a rock in the water.
- To find the volume of the rock, subtract the initial volume of the water from the final volume of the water: 50 mL – 30 mL = 20 mL.

**What is the property of a graduated cylinder?**

A graduated cylinder, also known as a measuring cylinder or mixing cylinder is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount of liquid that has been measured.

## What characteristic of matter can you measure using a graduated cylinder?

volume

The volume of a liquid can be measured directly with a graduated cylinder. The molecules of different liquids have different size and mass. The mass and size of the molecules in a liquid and how closely they are packed together determine the density of the liquid.

### What volume is shown in the graduated cylinder below?

Explanation: On this graduated cylinder there are 5 tick marks from 10 mL to 15 mL, so each tick mark represents 1 mL. The bottom of the meniscus is halfway between the tick marks representing 13 and 14 mL, so the best estimate of the volume is 13.5 mL.
