The ability to do work
Energy
the transfer of thermal energy from one substance to another.
Heat
Name at least three uses of fuels.
heating, cooking, drying clothes, generating electricity, making industrial products, transportation
is an instrument that measures temperature
A thermometer
any substance that releases energy when it burns.
fuel
stored energy, is the energy that an object or substance has because of its position or condition.
Potential Energy
substances that do not allow heat to move through them easily.
Insulators
Fossil fuels are formed when
the remains of plants and animals were buried quickly
The unit used to measure thermal energy.
calorie
When the substance’s particles may only move faster and occupy a larger space.
Thermal expansion-
the energy that an object or substance has because of its motion.
Kinetic energy
Radiation
heat transfer that occurs when there are no particles to carry the energy
What causes the heat that occurs when space vehicles take off or land?
Friction .
When a substance is heated the speed of the particles of the substance
increases
True or False
Convection occurs when there are no particles present.
False
the total kinetic energy of the particles in a substance
Thermal energy
Convection is
heat transfer that occurs when particles carry thermal energy as they move from one place to another.
Give an example of how thermal energy affects everyday life.
removing heat from a car engine or cooking hotdogs over a campfire
An insulator
does not allow heat to move through it easily.
What is shown in this picture
Thermal Expansion joint
the measure of the average kinetic energy of the particles in a substance.
Temperature
Conduction is
heat transfer that occurs when particles bump into each other but do not change location.
Why is controlling heat while in space so important?
for the safety of the crew and the protection of the equipment
allows heat to move through it easily.
A conductor
What type of energy is shown in the picture?
