Heat Capacity Formula:
From: | To: |
Definition: Heat Capacity is a physical property of matter, defined as the amount of heat to be supplied to a given mass of a material to produce a unit change in its temperature.
Purpose: It helps in understanding how much energy is required to change the temperature of a substance, which is crucial in thermodynamics, engineering, and material science.
The calculator uses the formula:
Where:
Explanation: The specific heat capacity is multiplied by the mass to get the total heat capacity of the object.
Details: Knowing the heat capacity helps in designing heating/cooling systems, understanding material properties, and calculating energy requirements for industrial processes.
Tips: Enter the specific heat capacity (default 4184 J/(kg·K) for water) and mass in kilograms. All values must be > 0.
Q1: What's the difference between heat capacity and specific heat capacity?
A: Heat capacity is extensive (depends on amount of material), while specific heat capacity is intensive (per unit mass).
Q2: What's a typical specific heat capacity for water?
A: Water has a high specific heat capacity of about 4184 J/(kg·K) at room temperature.
Q3: How does heat capacity vary with temperature?
A: For most materials, heat capacity changes with temperature, often increasing as temperature rises.
Q4: What units should I use for mass?
A: The calculator uses kilograms. Convert grams to kg by dividing by 1000.
Q5: Can this calculator be used for gases?
A: Yes, but note that gases have different specific heat capacities at constant pressure vs. constant volume.
