Heat in one look

specific heat, latent heat, and why a substance can take in energy without getting hotter

Heat and temperature are not the same

heat is energy in transit from a hotter body to a cooler one, measured in joules
temperature measures how hot a body is, in degrees Celsius or kelvin, and it decides which way heat will flow
a bucket of warm water holds more heat than a cup of boiling water, though the cup is at the higher temperature
the specific heat capacity c is the heat needed to raise one kilogram by one kelvin, in J kg⁻¹ K⁻¹
water has an unusually high specific heat, about 4200, which is why it heats and cools slowly
that high value is why water is used as a coolant, why coastal places have mild climates, and why a hot water bottle stays warm

The relations of this chapter

heat to change temperature Q = mcΔ T
heat to change state, no temperature change Q = mL
principle of heat exchange Q_lost = Q_gained
converting Celsius to kelvin T(K) = t(°C) + 273
relative humidity as a percentage RH = fracactual vapoursaturated vapour × 100

Latent heat, and the flat part of the graph

latent heat is the energy needed to change the state of one kilogram of a substance with no change in temperature
latent heat of fusion is for melting or freezing, and for ice it is about 3.34 × 10^5 J per kg
latent heat of vaporisation is for boiling or condensing, and for water it is about 22.6 × 10^5 J per kg, far larger
during a change of state the energy goes into breaking the forces between particles, not into speeding them up, so the thermometer does not move
that is why a heating curve has flat portions at the melting and boiling points
steam at 100°C burns worse than water at 100°C, because it gives up all that latent heat as it condenses on the skin

How CapCompass uses this sheet

These notes are not a standalone PDF. CapCompass plans Science chapter by chapter against your real exam dates and free hours, and when the plan reaches Heat the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
