thermal energy transfer through electromagnetic waves is called

25
ruber doesnt allow thermal energy to move through it easily. rubber is a
thermal insulater
26
According to the Kinetic Molecular model, heat comes from what
Particles in constant motion
27
What is temperature
Temperature is the measure of hotness or coldness of an object proportional to the average kinetic energy
28
What does the 2nd law of thermodynamics state
The law states that energy can flow from a colder object to a warmer object only if something does work
29
Rumfords cannon boring experiment revealed that a dull drill produced __?__ heat as __?__ metal was cut
more; less
30
What is a thermal conductor
A material through which thermal energy moves easily
31
What temperature does water boil for kevin
373.15
32
For a thermometer to produce reproducible measurements, it's scale is constructed on the basis of 2 known temperatures called what
Fiduciary points
33
What temperature does water boil for Celsius
100
34
which type of thermal energy transfer is demonstrated by the sun heating fabric seats in a car
radiation
35
According to the caloric theory heat was what
Heat was an invisible fluid
36
which of the following scientists showed a connection between one calorie of mechanical work and 4.18J of thermal energy
Fames Prescott Joule
37
Who challenged the caloric theory
Benjamin Thompson
38
How do thermoprometric properties make a liquid filled thermometer possible
As liquid expands the temperature goes up and when liquid cools it will contract
39
which type of thermal energy transfer is demonstrated by the rising of a hot air balloon
convection
40
Who was Benjamin Thompson also known as
Count Rumford
41
Which law states that entropy would be at its minimum value at absolute zero
Third
42
Thermal energy is affected by what 2 things
Temperature and number of particles
43
The idea that heat comes from the constant motion of particles is described by the __?__
kinetic-molecular model
44
What is the most commonly used scale worldwide
Celsius
45
the transfer of thermal energy is called ______
heat
46
Define heat
Heat is the movement of themal energy from an area of higher temperature to one of a lower temperature
47
Which law states that energy cannot be created or destroyed but only transferred between objects or transformed also known as the law of conservation of energy
1
48
On the particle level what happens when a warmer object comes into contact with a cooler on objects and how long will this occur
One particles move fast and cold particles move slow so the fast moving particles are moving towards the slow ones and they will collide this incurs until they are at the same temperature
49
What is the purpose of of expansion joints
To allow for thermal expansion of a structure, bridges, buildings, or roads
50
What is a thermal insulator
A thermal insulator is a material through which thermal energy does not move easily
51
We can change the state of materials be __?__ thermal energy
Adding
52
What does the 1st law of thermodynamics state
The law states that energy cannot be created or destroyed but only transferred between objects or transformed; known as the law of conservation of energy
53
Movement of thermal energy as fluids move
Convection
