Heat Capacity Formula:
From: | To: |
Definition: This calculator computes the amount of heat required to change a substance's temperature based on its mass, specific heat capacity, and temperature change.
Purpose: It helps in thermodynamics calculations for engineering, chemistry, and physics applications.
The calculator uses the formula:
Where:
Explanation: The formula calculates the amount of heat energy needed to achieve the specified temperature change for the given mass of material.
Details: Accurate heat capacity calculations are essential for designing heating/cooling systems, chemical reactions, and energy efficiency studies.
Tips: Enter the mass in kg, specific heat capacity (default 4184 J/(kg·K) for water), and temperature change in Kelvin. All values must be > 0.
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: What's a typical specific heat for water?
A: Water has a high specific heat capacity of about 4184 J/(kg·K) at standard conditions.
Q3: How does mass affect heat capacity?
A: Heat capacity is directly proportional to mass - doubling the mass doubles the heat required.
Q4: Can I use Celsius instead of Kelvin?
A: For temperature differences, 1°C = 1K, so you can use Celsius values for ΔT.
Q5: What materials have the highest heat capacity?
A: Water has one of the highest specific heat capacities among common substances.
