Question | Answer |
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. |
