Q

The quantity of heat required to raise the temperature of a unit mass of a substance 1° is known as __________.

🔍 Key Concepts

• latent heat is linked to phase change (solid↔liquid↔gas) without temperature change • sensible heat is heat you can measure as a temperature change • specific heat capacity involves both a unit of mass and a 1° temperature change

💭 Think About

• Which option’s definition clearly mentions BOTH a unit mass and a 1° change in temperature? • Ask yourself: does the process in the question involve a change of phase, or only a change in temperature? • Look at the words themselves: which term sounds like a property of the material itself (a characteristic number), not a type of heating process?

✅ Before You Answer

• Verify which term is defined as heat per unit mass per degree of temperature change. • Check that latent heat is tied to melting/boiling/etc. at constant temperature, not just warming something up. • Confirm that sensible heat is about temperature change you can detect, but does it include ‘per unit mass per degree’ in its definition?
