1. What is Heat Capacity?

Definition: Heat capacity is the amount of heat energy required to raise the temperature of a substance by one degree Kelvin.

Purpose: It helps in understanding how different materials absorb and store thermal energy, important in thermodynamics and material science.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Heat capacity (Joules per Kelvin)
• \( Q \) — Heat energy added (Joules)
• \( \Delta T \) — Temperature change (Kelvin)

Explanation: The heat energy is divided by the temperature change to determine how much energy the substance can store per degree of temperature change.

3. Importance of Heat Capacity

Details: Heat capacity helps in designing thermal systems, understanding climate patterns, and selecting materials for thermal applications.

4. Using the Calculator

Tips: Enter the heat energy in Joules and temperature change in Kelvin. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between heat capacity and specific heat?
A: Heat capacity is extensive (depends on amount of material), while specific heat is intensive (per unit mass).

Q2: Can heat capacity be negative?
A: Normally no, but in some special systems, negative heat capacity can occur.

Q3: What are typical heat capacity values?
A: Water has high heat capacity (4186 J/kg·K), metals typically range 100-1000 J/kg·K.

Q4: How does heat capacity relate to thermal conductivity?
A: They're different properties - heat capacity measures energy storage, while conductivity measures energy transfer.

Q5: Why use Kelvin instead of Celsius?
A: Kelvin is an absolute scale and required for thermodynamic calculations.
