Physical science March 11 Flashcards
How does Thermal energy move?
From hot to cold
What are the three common scales for measuring temperature
Fahrenheit Celsius and Kelvin scales
A material with high specific heat can absorb a great deal of Thermal energy without a change in what
Temperature
What is the formula for a change in energy
Mass times specific heat times change in temperature
What are the three ways heat is transferred?
Conduction convection and radiation
If two objects have different temperatures heat will flow from what to what?
Hot to cold
What transfers thermal energy well
Conductor
What does not transfer thermal energy well?
Insulator
Where are 3 states of matter
Solid liquid and gas
How can energy change from one state to another?
When thermal energy is absorbed or released
as thermal energy of matter increase what happens to the particles?
The particles spread out and the substance expand
Heat engines transform what energy to what energy
Thermal energy to mechanical energy
What’s is the device that transfers thermal energy from inside the refrigerator to the room outside
Refrigerator
A measure of the average kinetic energy of the individual particles in matter
Temperature
Most common temperature scale in the United States
Fahrenheit scale
The most common temperature scale in all other countries besides the United States
Celsius scale
The temperature scale commonly used in physical science
Kelvin scale
The temperature at which no more thermal energy can be removed from matter
Absolute zero
Thermal energy that is transferred from matter at a higher temperature to matter at a lower temperature is
Heat
The amount of energy required to raise the temperature of 1 kg of a material by 1 Kelvin is called
Specific heat
The process when heat is transferred from one particle of Matter to another without the movement of the particle
Conduction
When he is transferred by the Currents within a fluid
Convection
Is the transfer of energy by electromagnetic waves
Radiation
The flow that happens during convection creates a circular motion known as what
Convection current
