🔍 Key Concepts

• Latent heat vs. sensible heat (what changes and what stays the same) • Phase changes: melting, evaporation/boiling, sublimation • Whether latent heat applies to just one phase change or to any change of state

💭 Think About

• When latent heat is being added, what happens to the temperature of the substance during the phase change? • Does latent heat only apply to melting, or also to boiling and other state changes? • Think of ice melting, water boiling, and dry ice turning directly into gas—do they all involve latent heat?

✅ Before You Answer

• Be clear that latent heat is tied to a change of state, not a change in temperature. • Check if the definition you choose is only one specific change or covers all types of phase changes. • Confirm whether latent heat is required whenever a substance changes between solid, liquid, and vapor states.
