Consider air to be a diatomic gas with average mole moasses 29g/mole. A mass 1.45kg of air is contained in a cylinder with a piston at 2 7 0 C and pressure 1. 5 × 1 0 5 N / m 2. Energy is given to the system as heat and the system is allowed to expand till the final pressure 3. 5 × 1 0 5 N / m 2. As the gas expands, pressure and volume follow. S3 -3 Averaged CaCO Figure S2. The impacted CaCO3 mass fraction from Dp <1 µm was plotted as a function of average CaCO3 mass density (A), resulting in correction factors for CaCO3 mass density below 2.0 10-8 g cm-3.Similarly, correction factors for CaCO3 surface area density below 1.0 10-3 cm2 cm-3 were calculated by plotting the impacted CaCO3 surface area fraction from Dp < µm a Anhydrous nitric acid has a density of 1.513 g/cm 3 and has the approximate concentration of 24 molar. Anhydrous nitric acid is a colorless mobile liquid with a density of 1.512 g/cm 3 that solidifies at −42 °C to form white crystals [clarification needed]. As it decomposes to NO 2 and water, it obtains a yellow tint. It boils at 83 °C Kyselina chlorovodíková je těkavá bezbarvá kapalina. Patří mezi velmi silné žíraviny. Technická (tj. méně čistá) kyselina chlorovodíková je nažloutlá díky přítomnosti železitých iontů a prodává se pod názvem kyselina solná.
