Heat Capacity Calculator - Thermal Energy Storage

This physics calculator helps you calculate heat capacity and specific heat for various materials. Heat capacity is the amount of heat energy required to change the temperature of a substance.

Heat Capacity Definition

• Heat Capacity: Amount of heat to change temperature
• SI Unit: J/K (Joule per Kelvin)
• Formula: C = mc
• Specific Heat: Heat capacity per unit mass

Heat Capacity Formulas

• Heat Capacity: C = mc
• Heat Energy: Q = mcΔT
• Temperature Change: ΔT = Q/(mc)
• Molar Heat Capacity: C = Mc
• Specific Heat: c = Q/(mΔT)
• Phase Change: Q = mL

Applications

• Thermodynamics: Heat transfer and energy storage
• Engineering: Thermal system design
• Chemistry: Reaction heat calculations
