Using Heat
What is Mechanical Processes
Processes by which energy is transferred by work
What are the two equations we use for Celsius and Fahrenheit
°F = °C x 9/5 + 32
°C = (°F - 32) x 5/9
Define Conduction
Occurs between two objects in direct contact
What is the first law of Thermodynamics
First law = the total energy used in any process is conserved
Define Temperature
how hot or cold something is, measured using a definite scale
What is Specific heat
Can be used to figure out how much energy it takes to raise an object's temperature.
What is the second law of Thermodynamics
Second law = energy transferred as heat moves from the hotter object to the cooler object
List the 3 Temperature Scales
●Fahrenheit
●Celsius
●Kelvin
Energy transferred with electromagnetic waves
Energy Transfers is an increase in what....
Entropy
Finish the statements
A. More KE=......
B. Less KE=......
A. Hotter temperature
B. Cooler temperature
Define Convection
Results from the movement of warm fluids
What is Internal Combustion Engines
Fuel burns in cylinders within the engine
What is the Kelvin Scale
Absolute Zero: kinetic energy of an object would be zero. Has never been reached (particles are always in motion!) but scientists have come close.
What is the difference between a conductor and an insulator
A conductor is Material through which energy can be easily transferred as heat while an insulator is materials that transfer energy poorly.
