Heat Absorption Calculator
Calculate the amount of heat absorbed or released by a substance during temperature change using specific heat capacity.
How to Use This Calculator
- Enter the mass of the substance in grams
- Input the specific heat capacity in J/(g·°C) or select a material
- Enter the initial and final temperatures in degrees Celsius
- Click Calculate to see the heat absorbed or released
Formula Used
Q = m × c × ΔT
Where:
- Q = Heat absorbed or released (Joules)
- m = Mass of the substance (grams)
- c = Specific heat capacity (J/(g·°C))
- ΔT = Temperature change (Final Temperature - Initial Temperature, °C)
Example Calculation
Real-World Scenario:
Calculating the heat absorbed when heating 200g of water from 20°C to 80°C
Given:
- Mass (m) = 200 g
- Specific heat capacity of water (c) = 4.186 J/(g·°C)
- Initial temperature = 20°C
- Final temperature = 80°C
Calculation:
ΔT = 80°C - 20°C = 60°C
Q = 200 g × 4.186 J/(g·°C) × 60°C
Q = 50,232 Joules
Result: 50,232 Joules of heat absorbed
