Conduction, Convection, Radiation
What are the three methods of heat transfer?
Conduction, Convection, Radiation
What is Thermal Energy?
lt is the total random kinetic energy of all particles in an object.
what is heat?
The transfer of thermal energy from warmer to cooler areas.
What is an example of kinetic energy?
A moving car, a flying bird, a running child, or falling water.
how many sigh to we have?
6
what is the Definition of Convection?
Transfer of energy through the movement of liquids or gases
is heat the same as temperature?
No, heat is energy transfer, temperature is average kinetic energy.
what is Equilibrium?
Objects in contact will eventually reach the same temperature.
An object at rest has kinetic energy.
fasle
What planet is largest?
Jupiter)
ex of Convection?
Lava lamps, hot air balloons, ocean currents.
What happens to particles when they get colder?
They move slower and have less kinetic energy.
what is Thermal Energy?
The total kinetic energy of all particles in an object or system.
As a ball falls, potential energy converts into __________ energy.
Kinetic
Who want the football the game?
seahawks
what is a ex of Radiation? name two
Feeling warmth from a fire, getting a sunburn.
What is the difference between thermal energy and temperature?
Thermal energy is the total energy of particles, while temperature is the average kinetic energy of particles.
what does Thermal Equilibrium mean?
When two objects reach the same temperature and heat transfer stops.
What two factors affect kinetic energy?
Mass and speed
What is the only food that never spoils?
Honey
Why does a metal spoon in hot soup get hot?
How does particle motion affect thermal energy?
Faster-moving particles mean higher thermal energy and higher temperature.
what Insulator mean?
When two objects reach the same temperature and heat transfer stops.
How are Temperature and Kinetic Energy related?
Temperature is the measure of the average kinetic energy of particles; faster particles mean higher temperature.
