B.1.9—Specific heat and latent heat Topic Practice
Apply Q = mcΔT and Q = mL in single- and multi-step heating problems, checking units, power-time data and energy balance.
How this is tested
- use Q = mcΔT with P = E/t when needed to calculate c, ΔT or energy, checking kg and K units
- use Q = mL at the phase point to find energy transferred or mass melted or vaporized
- set up an energy-balance equation from a data table to compare specific heat capacities at equilibrium
