Physics 14: 5-8 Heat Transfer and Phase Change

Homework

Reading Preparation

Text Reading: Giancoli, Physics - Principles with Applications, Chapter 14: 5-8

Study Points

Key Equations

  • Latent Heat required for phase change: Q   =   mL
  • Thermal transfer rate (Conduction) Q t   =   kA   T 1     T 2 l

    k = Thermal conductivity value for substance
    A = surface area

  • Thermal transfer rate (Radiation) Q t   =   ϵ σ A   ( T 1 4     T 2 4   )  

    ε = emissivity
    σ = Stefan-Boltzmann constant = 5.67 * 10-8 W/m2*K4
