Specific Heat Formula:
From: | To: |
Specific heat (c) is the amount of heat energy required to raise the temperature of 1 kilogram of a substance by 1°C. It's an intensive property that varies between different materials and is crucial in thermodynamics and heat transfer calculations.
The calculator uses the specific heat formula:
Where:
Explanation: The formula shows that specific heat is inversely proportional to both mass and temperature change for a given amount of heat energy.
Details: Knowing a material's specific heat helps in designing heating/cooling systems, understanding thermal properties of materials, and calculating energy requirements for industrial processes.
Tips: Enter heat energy in Joules, mass in kilograms, and temperature change in °C. All values must be positive numbers.
Q1: What are typical specific heat values?
A: Water has a high specific heat of 4186 J/kg·°C, metals like iron have lower values (~450 J/kg·°C), while air is about 1005 J/kg·°C.
Q2: How does specific heat differ from heat capacity?
A: Specific heat is per unit mass (J/kg·°C), while heat capacity is for an entire object (J/°C) regardless of its mass.
Q3: Does specific heat change with temperature?
A: For most substances, yes - especially near phase changes. However, for small temperature ranges it's often treated as constant.
Q4: Why does water have such high specific heat?
A: Water's hydrogen bonding requires more energy to increase molecular motion (temperature), making it excellent for temperature regulation.
Q5: How is this used in real-world applications?
A: From designing car radiators and building insulation to calculating cooking times and climate modeling.
