🌡️ Temperature Change (ΔT) OR initial/final?

Enter ΔT (positive). For ΔT = T_final - T_initial

💡 Heat Energy (Q) - only for modes 2,3,4

📐 Specific Heat Formula: Q = m·c·ΔT

Q = heat energy (J), m = mass (kg), c = specific heat capacity (J/kg·K), ΔT = temperature change (°C or K). Sensible heat depends on material properties. Water's high specific heat (4184 J/kg·K) makes it excellent for thermal storage.

💧 Example 1: Heat 10kg water 20°C→80°C

🏭 Example 2: HVAC air heating (2 kg air ΔT=15°C)

🔩 Example 3: Find c of aluminum (Q=5000J, m=0.5kg, ΔT=11.14K)

⚙️ Example 4: Industrial boiler 500L water ΔT=70K

📘 Advanced thermodynamics insights

Why do metals heat faster than water?

Metals have low specific heat (e.g., Cu 385 J/kg·K) → less energy per degree. Water's high heat capacity enables stable temperatures in HVAC, engines, and climate systems.

Heat Capacity vs Specific Heat

Heat capacity (C = m·c) depends on mass; specific heat is intensive. Our tool supports engineering-grade conversions.

Applications: Boilers, chillers, heat exchangers, solar thermal, & UK HVAC load

Professional BTU calculators and sensible heat estimations used by engineers globally.
