Temperature
what is temperature?
The measure of hotness or coldness expressed in terms of any of several scales.
What is thermal energy?
Internal energy present in a system in a state of thermodynamic equilibrium by virtue of its temperature.
What is specific heat?
The quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree.
What is conduction?
The process by which heat energy is transmitted through collisions between neighboring atoms or molecules.
What is convection?
Process by which heat is transferred by movement of a heated fluid such as air or water.
hot and cold
What is heat?
Energy that is transferred from one body to another as the result of a difference in temperature.
What is specific heat measured in?
joules per gram per Celsius degree
What does conduction involve?
The transfer of energy from one atom to another through direct contact
What is radiation?
Energy that comes from a source and travels through space at the speed of light.

What is the difference between thermal energy and temperature?
Temperature measures the average kinetic energy the particles in a substance.
Thermal energy measures the total kinetic energy of the particles in a substance.
Can thermal energy manifest itself?
yes, manifests itself in multiple ways, such as in motion, sound, light, and thermal energy.
Can specific heat increase and decrease?
Yes specific heat can increase and decrease
What are good conductors?
Solids are efficient conductors
Radiation can come in many what?
Forms
samples cools as thermal energy is transferred to the water, so does the water increase?
yes, the water increases
What do warmer objects do?
Warmer objects heat the cooler objects
Do water have very high specific heat?
Yes water has very high specific heat
Where does conduction occur?
Solids and Liquids
