1. What is Density of Mercury?

Definition: Density (ρ) is mass per unit volume. Mercury has a very high density of approximately 13,593 kg/m³ at room temperature.

Purpose: Understanding mercury's density is important in physics, chemistry, and engineering applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The mass of mercury is divided by its volume to calculate density.

3. Importance of Mercury's Density

Details: Mercury's high density makes it useful in barometers, thermometers, and electrical switches. It's about 13.6 times denser than water.

4. Using the Calculator

Tips: Enter the mass in kilograms and volume in cubic meters. The default density of mercury is 13,593 kg/m³ if no values are entered.

5. Frequently Asked Questions (FAQ)

Q1: Why is mercury so dense?
A: Mercury atoms are heavy (atomic number 80) and packed closely together, resulting in high density.

Q2: Does mercury's density change with temperature?
A: Yes, like all liquids, mercury expands when heated, decreasing its density slightly.

Q3: How does mercury's density compare to other metals?
A: Mercury is less dense than gold (19,320 kg/m³) but more dense than lead (11,340 kg/m³).

Q4: Why is mercury liquid at room temperature?
A: Its electron configuration creates weak metallic bonds, allowing atoms to move past each other.

Q5: Is mercury the densest liquid?
A: At room temperature, yes. Some molten metals at high temperatures can be denser.
