What do you call this?
An object is the sum of the kinetic energy and the potential energy of all of the particles that make up that object
What is Thermal Energy
The Potential Energy increases as the particles move faster.
False/Kinetic Energy
Heat
Is the energy that is transferred between objects due to a temperature difference between those objects.
In the United States, the most common temperature scale is called the ____________ scale
Fahrenheit
_____________ Is thermal energy moving from a warmer object to a cooler object
Heat
A device that transforms radiant energy from the Sun into thermal energy
A Solar Collector
Conduction is the transfer of thermal energy in fluids by the movements of warmer and cooler fluid
False/Convection
Conduction
Is the transfer of thermal energy by collisions between the particles that make up matter
On this scale, the number 32 is assigned to the temperature at which water freezes.
Fahrenheit
Heat is transferred in three ways. Name the three ways.
Conduction, Convection, and Radiation
It usually passes more easily through gases than through solids or liquids because particles are much farther apart in gases than in solids or liquids
The thermal energy of an object is the measure of the average Kinetic energy of the particles that make up that object
False/Temperature
Specific Heat
Is the amount of heat needed to raise the temperature of 1 Kg of that material by 1*C
The temperature scale used in most of the world is _______________ scale
Celsius
Soup warming in a pot on the stove is an example of what kind of heat transfer?
Convection
In one of the ways in which energy manifests itself at the macroscopic scale
What is Thermal Energy
Thermodynamics is the study of the relationships among thermal energy, heat, and work
True
Internal combustion engine
Is a heat engine that burns fuel inside a set of cylinders
On this scale, the number 100 is assigned to the temperature at which water boils
Celsius
The tip of an iron poker sitting in a fire is an example of what type of heat transfer?
Conduction
States that if the mechanical energy of a system is constant, the increase in thermal energy of that system equals the sum of the thermal energy transfers into that system and the work done on that system.
The First Law of Thermodynamics
Conduction is faster in solids and liquids than it is in gases
True
Second law of thermodynamic
States that energy spontaneously spreads from regions of higher concentration to regions of lower concentration.
At this temperature, no more energy can be removed from matter
absolute zero
Heat lamps hanging above a buffet table at a restaurant are examples of what type of heat transfer?
Radiation
