Answer 2

What does density of an object show?

The density of an object is a measure of how much mass is contained within a given volume. It shows how tightly packed the particles of a substance are. Objects with higher density have more mass in a given volume, while objects with lower density have less mass in the same volume. Density is an important physical property that can provide information about the composition and characteristics of a substance.

In what units is density expressed?

Density is typically expressed in units of mass per unit volume. The most commonly used units for density are kilograms per cubic meter (kg/m³) in the International System of Units (SI). However, depending on the context, other units such as grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL) may also be used. It is important to ensure that the units of mass and volume are consistent when calculating or expressing density.

How can you achieve a more accurate determination of the density of a solid object using scales and a measuring cylinder?

To achieve a more accurate determination of the density of a solid object using scales and a measuring cylinder, you can follow these steps:

1. Measure the mass of the solid object using a scale. Make sure the scale is properly calibrated and provides accurate measurements.

2. Fill a measuring cylinder with a known volume of water. Note the initial volume of water in the cylinder.

3. Carefully lower the solid object into the measuring cylinder, ensuring that it is fully submerged in the water. Avoid introducing air bubbles.

4. Observe the change in water level in the measuring cylinder. The increase in volume corresponds to the volume of the solid object.

5. Calculate the density of the solid object using the formula: density = mass / volume.

By using a measuring cylinder and scales, you can obtain more precise measurements of the mass and volume of the solid object, leading to a more accurate determination of its density.
