Measurement
A temperature scale used in very few countries including the US that has specific melting, boiling, and freezing points.
What is Fahrenheit?
the relation between molar heat capacities at constant pressure Cp and at constant volume CV for an ideal gas.
what is mayars law?
Adding heat makes particles move ______?
Faster
The quantity that tells how warm or cold an object is
What is temperature?
The transfer of heat between particles as they collide within a substance or between two objects in contact.
What is conduction?
Metric unit used for measuring temperature, used around most of the world and by scientists.
What is celcius?
No system can reach absolute zero.
What is the 3rd law of thermodynamics?
As force of collision causes particles to move _______ apart, causing matter to ______
farther, expand
Capacity/ability to do work
What is energy?
0 degrees
What is the freezing point of salt water in fahrenheit?
Temperature scale that begins at absolute zero. The freezing point of water is 273_ and the boiling point is is 373_
What is the Kelvin Scale?
What is specific heat?
As particles move faster, they _______ with each other with greater force.
Collide
A material that is a poor conductor of heat energy.
What is an insulator?
212 degrees
What is the boiling point of water in Fahrenheit?
Temperature measurement device that uses a liquid that expands as the temperature increases.
What is a bulb thermometer?
Whenever heat flows into or out of a system the gain or loss of thermal energy equals the amount of heat transferred.
What is the 1st law of thermodynamics?
When an object starts moving, its potential energy becomes ______?
What is kinetic energy

what is the boiling point in celsuis
The amount of energy needed to raise the temperature of 1 gram of water by 1 degree C
What is Joule?
Heat never spontaneously flows from a lower-temperature substance to a higher-temperature substance.
What is the 2nd law of thermodynamics?
Heat will always be transferred from areas of high temperature to areas of lower temperature until _______ ___________ is reached.
What is thermal equilibrium?
Theoretical temperature at which molecules stop moving and no more heat can be removed from the object.
What is absolute zero?
amount of joules in 1 calorie.
