1. EVERYTHING YOU NEED TO KNOW
ABOUT HEAT
By Karson Campbell

2. HOW HEAT RELATES TO THERMAL
ENERGY
• Thermal energy refers to the energy contained within a system that is
responsible for its temperature.
• Heat is the flow of thermal energy.

3. THERMAL ENERGY
EXAMPLES
Thermodynamics, deals with how heat is
transferred between different systems and
how work is done in the process.
The First Law of Thermodynamics:
energy is always conserved, it cannot be
created or destroyed. In essence, energy
can be converted from one form into
another.

4. THE EFFECTS OF ENERGY
When you heat a substance the molecules
in the substance spread out and start
moving faster and cause expansion.
And this is relevant to gases, solids, and
liquids.

5. TEMPERATURE
Temperature is the measurement of how
hot or cold something is.
Temperature tells us the degrees of a
certain substance or area.

6. TYPES OF THERMOMETER
• Mercury Thermometer: Measures the
temperature of liquid.
• Alcohol Thermometer: Measures only up to 78
degrees Celsius.
Clinical Thermometer: measures body temperature.

7. CONDUCTION
Conduction: The process by which heat or
electricity is directly transmitted through a
substance when there is a difference of
temperature or of electrical potential between
adjoining regions, without movement of the
material.

8. CONVECTION
• Convection: Movement in a gas or liquid in which the warmer parts
move up and the cooler parts move down convection currents.

9. RADIATION
Radiation: The emission of energy as
electromagnetic waves or as moving subatomic
particles, especially high-energy particles which
cause ionization.
