Specific Heat Calculator Step-by-Step Guide

Introduction of Specific Heat

Ever wondered why one-of-a-kind materials warm up at exclusive prices? The answer lies in an asset called specific heat. This article dives into the idea of precise warmness and how a selected heat calculator can simplify complicated calculations. Whether you are a scholar, engineer, or just a curious mind, expertise, and precise warmth is critical for numerous clinical and realistic programs.

Understanding Specific Heat

Definition of Specific Heat

Specific Heat is the amount of warmth strength required to elevate the temperature of 1 gram of a substance through one diploma Celsius. It essentially tells us how a whole lot of energy a fabric can shop.

Units of Measurement

The preferred unit for precise warmness is joules in keeping with gram in line with diploma Celsius (J/g°C) in the SI machine, however calories in step with gram per diploma Celsius (cal/g°C) are also generally used.

Specific Heat Capacity Formula

The specific heat capacity (c) of a substance is calculated using the formula:

\( c = \frac{q}{m \Delta T} \)


  • c = specific heat capacity (J/kg·K)
  • q = heat energy added or removed (Joules, J)
  • m = mass of the substance (kilograms, kg)
  • ΔT = change in temperature (Kelvin, K)


  1. Heat Energy (q): This is the amount of heat energy supplied to or taken away from the substance. It is measured in Joules (J).
  2. Mass (m): This is the mass of the substance being heated or cooled. It is measured in kilograms (kg).
  3. Change in Temperature (ΔT): This is the difference in temperature as a result of the heat added or removed. It is calculated as ΔT = Tfinal - Tinitial and is measured in Kelvin (K).

Example 1

Let's say we have 2 kg of water, and we want to calculate its specific heat capacity. We know the following:

  • The heat energy added (q) is 10000 J.
  • The initial temperature (Tinitial) is 20°C, and the final temperature (Tfinal) is 30°C.


First, convert the temperatures to Kelvin. However, since the change in temperature in Celsius is the same as in Kelvin, we can use the temperature difference directly:

\( \Delta T = 30 - 20 = 10 \, \text{K} \)

Now, using the specific heat capacity formula:

\( c = \frac{q}{m \Delta T} = \frac{10000 \, \text{J}}{2 \, \text{kg} \times 10 \, \text{K}} = \frac{10000}{20} = 500 \, \text{J/kg·K} \)

Example 2

Consider a 3 kg block of copper. We supply it with 5000 J of heat energy, causing its temperature to increase from 25°C to 35°C.

Again, the change in temperature is:

\( \Delta T = 35 - 25 = 10 \, \text{K} \)

Using the specific heat capacity formula:

\( c = \frac{q}{m \Delta T} = \frac{5000 \, \text{J}}{3 \, \text{kg} \times 10 \, \text{K}} = \frac{5000}{30} \approx 166.67 \, \text{J/kg·K} \)
