Conduction

• Particles touching (travel fastest through a solid)

• Measure of kinetic energy

• The transfer of thermal energy in a fluid

NGSS.MS-PS3-3

Convection

• Transfer of thermal energy in a fluid by the movement of the fluid from place to place (fluids are a gas or a liquid).  Travels fastest through a gas or liquid 

• The transfer of thermal energy between colliding particles.  Travels fastest through a solid. 

• transfer of electromagnetic waves.  Travels fastest through a vacuum (where there is no matter)

Radiation

• transfer of electromagnetic waves.  Travels fastest through a vacuum (where there is no matter)

• material in which thermal energy moves slowly (ex. Anything with air pockets, plastic, wood)

• materials in which thermal energy is easily transferred  (ex. metals)

What does the first law of thermodynamics state

(a)  

Answer explanation

The increase in thermal energy of a system equals the work done on the system plus the thermal energy transferred to the system
