1. What is a Specific Heat Calculator?

Definition: This calculator determines the specific heat capacity of a substance using the heat energy added, mass of the substance, and temperature change.

Purpose: It helps students and professionals in chemistry and physics calculate how much energy is required to change a substance's temperature.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( c \) — Specific heat capacity (J/kg·K)
• \( Q \) — Heat energy added (Joules)
• \( m \) — Mass of the substance (kg)
• \( \Delta T \) — Temperature change (Kelvin)

Explanation: The heat energy is divided by the product of mass and temperature change to determine how much energy is needed per unit mass to change the temperature by 1 degree.

3. Importance of Specific Heat Calculation

Details: Specific heat capacity is crucial for understanding thermal properties of materials, designing heating/cooling systems, and solving calorimetry problems.

4. Using the Calculator

Tips: Enter the heat energy in Joules, mass in kilograms, and temperature change in Kelvin. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are typical specific heat values?
A: Water has high specific heat (4186 J/kg·K), metals are lower (e.g., iron ~450 J/kg·K), while air is about 1005 J/kg·K.

Q2: Why use Kelvin for temperature change?
A: Kelvin and Celsius degrees are the same size, but Kelvin ensures positive values since it's an absolute scale.

Q3: Can I use grams instead of kilograms?
A: Yes, but you'll need to adjust units (1 kg = 1000 g) and the result will be in J/g·K instead of J/kg·K.

Q4: What if my temperature decreases?
A: Use the absolute value of temperature change (ΔT is always positive in this calculation).

Q5: How does specific heat relate to heat capacity?
A: Heat capacity is extensive (depends on amount), while specific heat is intensive (per unit mass).
