Topic Summary: Specific Heat Capacity
Key Terms
- SHC (c): energy to raise 1 kg of a substance by 1°C (J/kg°C)
- Δθ: temperature change = final − initial (°C)
- Thermal equilibrium: no net heat flow between objects
- Systematic error: consistent offset due to heat loss
Key Equation
- ΔE = mcΔθ
- c = ΔE / (mΔθ)
- Δθ = ΔE / (mc)
- Water SHC = 4200 J/kg°C
Key Facts
- High SHC = slow to heat/cool (stores lots of energy)
- Low SHC = heats up and cools quickly
- Experimental SHC always too HIGH (heat loss to surroundings)
- Water used in heating because of its very high SHC
Exam Tips
- Δθ is temperature CHANGE, not final temperature
- Mass in kg — convert from grams!
- Practical result too high → heat loss to surroundings
- Improvements: insulate block, oil in thermometer hole
