Thermal Energy, Heat & Temperature
The total kinetic and potential energy of particles in an object AND what is it measured in
Thermal Energy - measured in joules
Heat transfer occurs only from __________ objects to __________ ones.
Warmer objects to Colder objects.
A material that conducts heat poorly is called a(n) __________________.
insulator
The movement of thermal energy from a warmer object to a cooler object is called _______________.
heat
Ms. B taught this subject last year
What is math?
At this temperature, particles would theoretically have no kinetic energy and be completely motionless.
What is 0 degrees Kelvin aka abolsute Zero?
When electromagnetic waves transfer heat.
What is radiation?
A material that conducts heat well.
What is a conductor?
As most substances are cooled, they _________________.
Contract
The mascot of Ms. B's college
What is gamecocks?
When thermal energy of an object changes
What is heat transfer?
During_____________, heat is transferred by the movement of currents within a fluid.
Convection
A measure of the average ____________ energy of the individual particles in an object is called temperature.
Kinetic
The amount of energy required to raise the temperature of 1 kg of a material by 1 kelvin
What is specific heat?
Ms. B is this astrological sign -- hint, it kinda connects to her major in college!
What is Pisces?
True or False. Hot Chocolate can heat the surrounding air.
True
Heat is transferred from one particle of matter to another within an object or between two objects that come in contact is a process called ____________________
Conduction
Joints in train tracks are designed with extra space to allow for __________________ in hot weather.
Thermal Expansion
Aluminum has a specific heat of 900 (J/(kg x K)). Iron has a specific heat of 450 (J/(kg x K)). Which material would require less energy to heat up?
What is iron?
This is Ms. B's home state bird
What is the Baltimore Oriole?
Describe the particle motion as an ice cube melts on the counter
The 3 ways thermal energy is transferred are _____, _____, ______ & give an example for each
Convection - water boiling, Conduction- stepping on hot sand, Radiation - sun
Describe how conductors and insulators differ. Include an example of each.
DOUBLE Jepoardy
A material that prevents the flow of energy is called an insulator. A material that permits the flow of energy is called a conductor.
An example of an insulator would be air, wool, plastic, etc.
An example of a conductor would be silver, aluminum, iron, metal
If two glasses of water are at the same temperature, the average kinetic energy of the particles of water in each glass is the _______________.
Same
