比熱計算機

Q = mcΔT から比熱容量を求めます。

はじめに

Specific Heat Calculator — Specific heat capacity solved from Q = mcΔT. Enter Heat (J), Mass (kg), Temperature change (K) to get an instant, accurate result.

計算式

Specific heat capacity is calculated by solving the heat equation for c: c = Q / (m × ΔT), where Q is the heat energy absorbed or released, m is mass, and ΔT is the temperature change.

ステップごとの説明

  1. Enter the Heat (J).
  2. Enter the Mass (kg).
  3. Enter the Temperature change (K).
  4. Click Calculate to see your result instantly.

実例

Example: With Heat (J) = 8372, Mass (kg) = 2, Temperature change (K) = 10, the Specific Heat Calculator gives Specific Heat J Kg K: 418.6.

よくある質問

What does specific heat tell you about a material?
Specific heat indicates how resistant a material is to temperature change — materials with high specific heat (like water) require more energy to heat up than materials with low specific heat (like metals).
What units are used for specific heat?
Specific heat is typically expressed in joules per kilogram per degree Celsius, J/(kg·°C), consistent with heat in joules, mass in kilograms, and temperature change in °C.
Can I use this to identify an unknown material?
Yes, calculated specific heat values can be compared against reference tables of known materials (e.g., aluminum ≈ 900 J/(kg·°C), copper ≈ 385 J/(kg·°C)) to help identify a substance.
What inputs does the Specific Heat Calculator need?
You'll need to provide: Heat (J), Mass (kg), Temperature change (K). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Specific Heat Calculator?
The Specific Heat Calculator applies the formula exactly as calculated — Specific heat capacity is calculated by solving the heat equation for c: c = Q / (m × ΔT), where Q is the heat energy absorbed or released, m is mass, and ΔT is the temperature change. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Specific Heat Calculator free to use?
Yes, the Specific Heat Calculator is completely free, requires no signup, and runs instantly in your browser.

比熱計算機について

The Specific Heat Calculator uses a real, verifiable formula — Specific heat capacity is calculated by solving the heat equation for c: c = Q / (m × ΔT), where Q is the heat energy absorbed or released, m is mass, and ΔT is the temperature change. — so results are accurate every time, not an approximation.
