Formula Guide
Formulas, units, examples, and limits
Formula scope
- Heat pages use Q = m*c*delta_T and c = Q/(m*delta_T) for temperature-change energy.
- Thermal expansion uses delta = measure*n*alpha*delta_T for linear, area, or volume estimates.
- Gas and entropy pages use PV = nRT and delta_S = Q/T with absolute temperature where required.
Variables and units
- Heat Q in J, mass m in kg, specific heat c in J/kg*K, temperature change in K or C interval.
- Expansion coefficient alpha in 1/K, length or volume in SI units, entropy in J/K.
- Gas pressure in Pa, volume in m^3, amount in mol, absolute temperature in K.
Worked example
Back-solve a material specific heat
- 1For Q = 12500 J, m = 2 kg, and delta_T = 15 K, compute c = 12500/(2*15).
- 2Result: c = 416.67 J/kg*K.
- 3Check whether the experiment crossed a phase change before treating that value as a material property.
Thermodynamics pages require careful separation of absolute temperature, temperature change, and phase-change energy.
Common limits and checks
- Specific heat is treated as constant over the interval.
- Thermal expansion assumes uniform temperature and unconstrained movement.
- Ideal gas formulas need absolute pressure and absolute temperature.

About Thermodynamics Calculators
Thermodynamics calculators support the standard heat-transfer and gas-law formulas used across physics, chemistry, and engineering courses. The tools here focus on repeated physics workflows rather than broad textbook coverage.
Each tool is designed to reduce equation setup time while keeping the result transparent enough to support homework checks, lab work, or engineering back-of-the-envelope estimates.
Why these formulas belong together
Users usually arrive with a cluster of closely related questions. Someone solving projectile motion may also need velocity or free-fall results, and someone working on RC timing may also need Ohm's law or voltage-divider outputs.
Grouping these calculators by topic helps you move between related formulas without losing the physics context, whether you are comparing motion, circuits, heat, waves, fluids, or gravity problems.
Thermodynamics Calculators FAQ
Use this page when you know the subject area but still need the right formula tool. Jump straight to a tool when you already know the exact calculation.
Switch topics when the variables or formula family change, such as moving from motion to circuits or from heat to gases.
No. These calculators help with setup and checking, but they should not replace course materials, lab guidance, or engineering review when those are required.
