Basic terminology needed for heat temp Flashcards
kinetic in particles
Kinetic energy in particles vary from state of matter such as solid has low kinetic.
Potential energy in particles
Stored energy found in chemical bonds in matter.
Thermal energy
Thermal energy is heat being placed onto an object like conduction or convection.
Internal energy
Is the potential and kinetic energy in a system.
Macroscopic energy
Kinetic and potential energy in particles in a substance.
Microscopic energy
Is energy in a system on a molecular level, thus internal energy between atomic bonds.
Thermal equilibrium( hot tea on a table)
two substances in physical contact with each other transfer heat. eventually the object will reach same temp as each other.
Zeroth Law Thermodynamics ( water class and table will all be the same temperature eventually.)
if two bodies are each in thermal equilibrium with some third body, then they are also in equilibrium with each other.
Specific heat capacity (q=mcat)
water specific heat capacity (4.186J/G°C)
Quantity of thermal energy required to raise (temp) of a substance of a kg to 1 C/K
Calorimetry Qlost+Qgained
measuring the amount of heat transferred between object.
Specific latent heat (Multiple formula)
Specific latent heat is the amount of energy required to turn an objects matter from solid, liquid and to vapourisation.
Heat transfer (e.gconduction/convection)
Transferring thermal energy from one object to another convection, conduction and radiation.
Three form explanation of heat transfer
Conduction is the physical contact transfer.
Convection is heat transferred by movement example air or fluid.
radiation is transferred through electromagnetic waves or particles.
Thermodynamics first law (U=Q+W)
energy cannot be created or destroyed; it can only be converted from one form to another.
Heat engine
A heat engine is a device that converts heat to work. rest exits waste(hot air out system)
