1. What is the Heat Absorbed Equation?

The heat absorbed equation calculates the amount of heat energy transferred to or from a substance. For water, it uses the formula Q = m × c × ΔT, where Q is heat, m is mass, c is specific heat capacity, and ΔT is temperature change.

2. How Does the Calculator Work?

The calculator uses the heat absorbed equation:

Where:

• \( Q \) — Heat absorbed (Joules)
• \( m \) — Mass of water (grams)
• \( c \) — Specific heat capacity (J/g·°C)
• \( \Delta T \) — Temperature change (°C)

Explanation: The equation calculates the thermal energy required to change the temperature of a given mass of water by a specific amount.

3. Importance of Heat Calculation

Details: Calculating heat absorption is crucial in thermodynamics, chemistry experiments, cooking, and various industrial processes where temperature control is important.

4. Using the Calculator

Tips: Enter mass in grams, specific heat capacity in J/g·°C (4.184 for water), and temperature change in °C. All values must be valid (mass > 0, specific heat > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is specific heat capacity?
A: Specific heat capacity is the amount of heat required to raise the temperature of 1 gram of a substance by 1°C.

Q2: Why is water's specific heat 4.184 J/g·°C?
A: This value is experimentally determined and represents water's high capacity to absorb heat without significant temperature change.

Q3: Can this calculator be used for other substances?
A: Yes, by changing the specific heat value, you can calculate heat absorption for any substance.

Q4: What does a negative ΔT value mean?
A: A negative ΔT indicates temperature decrease, and the calculated Q value represents heat released rather than absorbed.

Q5: How accurate is this calculation?
A: The calculation is theoretically accurate for ideal conditions where specific heat remains constant across the temperature range.
