Thermodynamics Calculator
Calculate heat transfer, specific heat, and temperature change using Q = mcΔT. Solve calorimetry and thermal equilibrium problems.
What is Thermodynamics Calculator?
This thermodynamics calculator solves the heat equation Q = mcΔT (heat = mass × specific heat × temperature change) for any unknown variable. Includes specific heat values for common materials and handles heat exchange equilibrium problems.
How to Use This Calculator
- Enter your Initial Pressure P₁, Initial Volume V₁, Initial Temp T₁, and other required values in the input fields
- Results are computed instantly as you enter or modify values — no need to click a button
- Review the computed output showing your thermodynamics results with a detailed breakdown
- Verify the result against your textbook or lab data and note the units used in the output
How Thermodynamics Calculator is Calculated
This calculator uses the formula: PV = nRT | Boyle: P₁V₁ = P₂V₂ | Charles: V₁/T₁ = V₂/T₂. Where P = Pressure ; V = Volume ; n = Moles ; R = 0.0821 L·atm/mol·K ; T = Temperature (K). Ideal gas law relates pressure, volume, temperature and amount. R is the universal gas constant. All calculations run entirely in your browser — no data is transmitted to any server.
Frequently Asked Questions
What is specific heat capacity?
The energy needed to raise 1 kg of a substance by 1°C. Water has unusually high specific heat (4,186 J/kg°C), which is why it is used for cooling and heating systems. Iron: 449. Aluminum: 897. Copper: 385 J/kg°C.
How does Q = mcΔT work?
To heat 2 kg of water from 20°C to 100°C: Q = 2 × 4186 × 80 = 669,760 J ≈ 670 kJ. This is about 0.19 kWh of energy. An electric kettle (2,000W) would take 335 seconds or about 5.5 minutes.
