Sensible heat causes a measurable change in temperature without altering the physical state of a substance. Latent heat changes the physical state of a substance at a constant temperature without any change showing on a thermometer.
Learning Objectives
Distinguish between sensible heat and latent heat during thermal processes in plumbing systems
Explain the temperature and phase changes that occur when water transitions between ice, water, and steam
Identify the specific quantities of energy involved in heating water and changing its state
