Calculate the energy, gas volume, moles produced, and time required for any sublimation process with scientific precision
Observe how molecules transition from solid lattice to free gas phase
Enter your parameters below to calculate sublimation results
Enter your parameters and click Calculate to see detailed sublimation results.
Choose from 7 common substances — dry ice, iodine, naphthalene, camphor, arsenic, ammonium chloride, or water ice.
Input the mass of your solid in grams, kilograms, milligrams, or pounds.
Provide the initial temperature of the solid in °C, °F, or Kelvin.
Click Calculate to see total energy, gas volume, moles produced, and estimated time.
The calculator uses Q₁ = m × c × ΔT for sensible heating to the sublimation point, and Q₂ = m × L for the latent heat of phase change. Gas volume is calculated using the Ideal Gas Law: PV = nRT, where n = mass / molar mass.
The calculator uses NIST-verified thermodynamic data for all 7 substances. Results are accurate for ideal conditions at the specified pressure. Real-world results may vary due to impurities, container geometry, and ambient conditions.
Yes! Enter a heating power value (in Watts) in the optional field. The calculator will estimate how long the sublimation process takes based on the total energy divided by the power input.
Mass: grams, kilograms, milligrams, pounds. Temperature: Celsius, Fahrenheit, Kelvin. Pressure: atm, Pa, kPa, mmHg. Energy output is shown in Joules, kJ, calories, kcal, BTU, and Wh.
The initial temperature determines Q₁ — the sensible heat needed to raise the solid to its sublimation point. If your solid is already at the sublimation temperature, Q₁ will be zero and only the latent heat (Q₂) is needed.
Sensible heat (Q₁) raises the temperature of the solid without changing its phase. Latent heat (Q₂) is the energy needed for the actual phase change from solid to gas, without any temperature change during the transition.
