How to use the molar heat capacity calculator
Find the molar heat capacity of a substance from the heat absorbed and temperature rise. Enter heat absorbed, amount of substance, temperature rise in the fields above; the molar heat capacity, heat capacity of sample are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “molar heat capacity”, “J per mol per K”, “heat capacity per mole”, “calculate molar heat capacity”, “find molar heat capacity”.
Formula
Variables
- q — Heat absorbed (J)
- n — Amount of substance (mol)
- dT — Temperature rise (K)
Worked example
With heat absorbed = 500 J, amount of substance = 0.5 mol, temperature rise = 10 K, the calculator gives molar heat capacity ≈ 100 J/(mol·K); heat capacity of sample ≈ 50 J/K.
Frequently asked questions
What is the molar heat capacity calculator used for?
Find the molar heat capacity of a substance from the heat absorbed and temperature rise. It helps with questions such as “molar heat capacity”, “J per mol per K”, “heat capacity per mole”.
What is the formula for the molar heat capacity calculation?
Molar heat capacity (J/(mol·K)) = q / (n × dT). Heat capacity of sample (J/K) = q / dT. Here q is heat absorbed (J), n is amount of substance (mol), dT is temperature rise (K).
What inputs do I need for the molar heat capacity calculator?
You need heat absorbed in J, amount of substance in mol, temperature rise in K. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the molar heat capacity calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the molar heat capacity result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
