1. What is a Temperature Change Calculator?

Definition: This calculator determines the temperature change of a substance when heat energy is added or removed, based on its mass and specific heat capacity.

Purpose: It helps in thermodynamics calculations for physics, engineering, and chemistry applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The heat energy is divided by the product of mass and specific heat to determine the temperature change.

3. Importance of Temperature Change Calculation

Details: Accurate temperature change calculations are crucial for thermal system design, material selection, and energy efficiency analysis.

4. Using the Calculator

Tips: Enter the heat energy in Joules, mass in kilograms, and specific heat (default 4186 J/kg·K for water). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is specific heat capacity?
A: It's the amount of heat required to raise the temperature of 1 kg of a substance by 1 Kelvin.

Q2: Why is water's specific heat 4186 J/kg·K?
A: Water has a high specific heat capacity, meaning it can absorb much heat with little temperature change.

Q3: Can I use this for cooling calculations?
A: Yes, just use negative heat values for heat removal (though the calculator will show absolute change).

Q4: How do I convert between Kelvin and Celsius?
A: The size of 1K equals 1°C, so the numerical change is the same in both scales.

Q5: What are typical specific heat values?
A: Aluminum ~900 J/kg·K, Iron ~450 J/kg·K, Ice ~2100 J/kg·K, Air ~1000 J/kg·K.
