Thermal Energy

QuestionAnswer
WHat is the definition of convection? The transfer of heat energy through a liquid or gas.
What is the definition of conduction? The transfer of heat through direct contact.
What is the definition of radiation? The transfer of heat energy through the emptiness of space.
What is the definition of heat? Energy that is based on the temperature and the mass of an object.
What is the definition of temperature? The measure of how hot or cold something is.
What is Celsius? A temperature scale based on the freezing and boiling point of water.
What is Kelvin? A temperature scale based on absolute zero.
What is Fahrenheit? A temperature scale based on the freezing point of water at 32 degrees.
What is a calorie? The amount of energy needed to change the temperature of one gram of water one degree Celsius.
What is the water cycle? Evaporation-Condensation-Percipataion
Are heat and temperature the same thing? No
What is an insulator? A material that does not conduct heat well.
What is a conductor? A material that conducts heat well.
What are some examples of insulators? styrofoam cups, wood, glass, plastic, rubber, etc.
What are some examples of conductors? metal: including iron, copper, steel, etc., water
What is a temperature? The measure of how hot or cold something is. It is also the average KE of the particles in a substance.
What is thermal energy-heat? A transfer of thermal energy from a warmer object to a cooler object. Heat is caused by the internal motion of molecules of matter. It depends on the total KE of the particles.
LIQUID to a GAS -vaporization -evaporation -boiling
LIQUID TO A SOLID freezing
SOLID TO A LIQUID melting
GAS TO A LIQUID condensation
SOLID TO A GAS sublimaton
GAS TO A SOLID deposition
What is the definition of matter? Anything that takes up space. (i.e.-almost anything)
What are the the 3 types of heat transfer? convection, conduction, and radiation
What are the particles acting like in thermal energy? They are vibrating which creates heat.
What are the particles acting like in gas? They are moving around very quickly and passing each other often.
What are the particles acting like in liquid? They are moving around quickly and sometimes pass each other.
What are the particles acting like in a solid? They are mostly staying in the same spot.
