⚠️ Common Misconceptions
Misconception 1: "Temperature and thermal energy are the same"
Temperature measures the average kinetic energy per particle — it tells you how hot something is. Thermal energy is the total energy stored in ALL the particles. A bathtub of lukewarm water (e.g., 40°C) has far more thermal energy than a small cup of boiling water (100°C), because the bathtub contains vastly more particles. SHC relates these two quantities.
Misconception 2: "The experimental SHC should exactly match the accepted value"
In the required practical, your calculated SHC will always be higher than the accepted value because energy is lost to the surroundings via conduction and convection. This is not an experimental "mistake" — it's an unavoidable source of systematic error. The answer to "why is your value too high?" is always: heat loss to surroundings, so the measured energy input is higher than the energy actually stored in the block.
Misconception 3: "Δθ means the final temperature"
Δθ (delta theta) is the temperature CHANGE — it is final minus initial. If water is heated from 20°C to 80°C, Δθ = 60°C, not 80°C. Using the final temperature instead of the change is one of the most common calculation errors in SHC questions.
