1. What is CO2 Density Conversion?

Definition: This calculator converts the density of carbon dioxide (CO2) from kilograms per cubic meter (kg/m³) to grams per cubic centimeter (g/cm³).

Purpose: It helps scientists, engineers, and students working with CO2 gas to convert between different density units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density in grams per cubic centimeter (g/cm³)
• \( \rho_{kg/m³} \) — Density in kilograms per cubic meter (kg/m³)

Explanation: Since 1 kg/m³ equals 0.001 g/cm³, we divide the kg/m³ value by 1000 to convert to g/cm³.

3. Importance of CO2 Density

Details: CO2 density is crucial for various applications including carbon capture, beverage carbonation, fire suppression systems, and climate science.

4. Using the Calculator

Tips: Enter the CO2 density in kg/m³ (default 1.98 kg/m³ for CO2 at STP). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the density of CO2 at standard conditions?
A: At STP (0°C, 1 atm), CO2 has a density of about 1.98 kg/m³ or 0.00198 g/cm³.

Q2: How does temperature affect CO2 density?
A: CO2 density decreases with increasing temperature (Charles' Law) and increases with pressure (Boyle's Law).

Q3: Why convert between kg/m³ and g/cm³?
A: Different scientific fields use different units. g/cm³ is common in chemistry while kg/m³ is standard in physics and engineering.

Q4: Is CO2 denser than air?
A: Yes, CO2 (1.98 kg/m³) is denser than dry air (1.29 kg/m³) at STP, which is why it accumulates in low-lying areas.

Q5: How does CO2 density compare to water?
A: CO2 gas is much less dense than water (~1000 kg/m³). Liquid CO2 at high pressure has density around 770 kg/m³.
