1. What is a Water Density Calculator?

Definition: This calculator determines the density of water based on its mass and volume using the fundamental density formula.

Purpose: It helps scientists, engineers, and students calculate water density for various applications in physics, chemistry, and engineering.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The mass of water is divided by its volume to obtain density. Pure water at 4°C has a density of exactly 1000 kg/m³.

3. Importance of Water Density Calculation

Details: Water density is crucial for buoyancy calculations, fluid dynamics, and various engineering applications. It changes with temperature and salinity.

4. Using the Calculator

Tips: Enter the mass of water in kilograms and volume in cubic meters. Both values must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the density of pure water at 4°C?
A: Pure water reaches its maximum density of exactly 1000 kg/m³ at 4°C.

Q2: How does temperature affect water density?
A: Water density decreases as temperature increases above 4°C and decreases slightly as it cools below 4°C.

Q3: What's the density of seawater?
A: Seawater is denser, typically about 1020-1030 kg/m³ due to dissolved salts.

Q4: Why is 4°C special for water density?
A: Water has its maximum density at 4°C, which is why ice floats and lakes freeze from the top down.

Q5: How precise is this calculator?
A: It provides theoretical density based on your inputs. For precise scientific work, consider temperature and purity factors.
