Temperature
temperature
Is the measure of the average Kinetic Energy of the particles that make up that object.
Is the sum of the kinetic energy and the potential energy of all the participles that make up that objects.
thermal energy
is the energy that is transferred between objects due to a temperature difference between those objects.
heat
What is radiation?
Is the transfer of energy by electromagnetic waves,such as light and microwaves.
What is a thermal insulator?
is a material through which thermal energy moves slowly.
What is the equation to calculate heat energy?
What is Potential Energy?
it is energy that will or could happen
Is the amount of heat needed to raise the temperature.
Specific Heat
How does the sun heat the earth?
The Sun lets heat energy by burning and it enters and warms our atmosphere
Name and example of a good Thermal Insulator
wood, fiberglass, air
What is one Kelvin equal to?
one degree Celsius
What is Kinetic Energy?
the energy that is applied to a moving object
What is heat measures in?
joules
Name three examples of electromagnetic waves
radio, micro, ir, visible light, uv, gamma, x ray
What is a poor Thermal Insulator?
metals and other good conductors
quickly
Example: Conduction, Convection, Radiation:
You are popping popcorn in a popcorn popper that is on the stove.
Conduction
Does water have a high or low specific heat?
high
Why does Radiation pass through gasses fast then a solid?
Because gas particles are more spread out and have more kinetic energy
In conductors, thermal energy moves how?
Quickly from warmer to cooler
Calculate the heat energy of 2 kg of water that cools from 20 degrees to 10 degrees. The specific heat of water is 4180 J/kg*C
Examples: conduction, convection, or radiation?
The sun makes the sand really hot.....
And then you burn your feet on the hot sand....
radiation
conduction
Does metals have a high or low specific heat?
low
The amount of energy that a material absorbs, reflects and transmits depends on what?
the type of material
Name three insulators used in the construction of a new home.
Insulation, Windows, Glass
