Specific Heat Formula:
From: | To: |
Definition: Specific heat is the amount of heat energy required to raise the temperature of 1 kilogram of a substance by 1 Kelvin.
Purpose: It helps determine how much energy is needed to heat or cool materials and compares how different substances absorb heat.
The calculator uses the formula:
Where:
Explanation: The heat energy is divided by the product of mass and temperature change to determine the specific heat capacity.
Details: Understanding specific heat is crucial for thermal system design, material selection, and energy efficiency calculations in engineering and physics.
Tips: Enter the heat energy in Joules, mass in kilograms, and temperature change in Kelvin. All values must be > 0.
Q1: What are typical specific heat values?
A: Water has a high specific heat of 4186 J/kg·K, while metals like iron (450 J/kg·K) and aluminum (900 J/kg·K) have lower values.
Q2: Can I use Celsius instead of Kelvin?
A: Yes, because ΔT is the same in both scales (1°C change = 1K change).
Q3: Why is specific heat important in daily life?
A: It explains why water heats/cools slowly (good for temperature regulation) and why metals feel hot/cold quickly.
Q4: How does specific heat relate to thermal conductivity?
A: They're different properties - specific heat measures heat storage capacity, while conductivity measures heat transfer rate.
Q5: What's the difference between specific heat and heat capacity?
A: Specific heat is per unit mass (J/kg·K), while heat capacity is for an entire object (J/K).
