Ii: Termodinгўmica E Ondas - Fг­sica

Energy cannot be created or destroyed, only transformed. In a system, the change in internal energy is equal to the heat added minus the work done by the system (

If two systems are in thermal equilibrium with a third system, they are in equilibrium with each other. This is the basis for how thermometers work. FГ­sica II: TermodinГўmica e Ondas

Waves are disturbances that travel through a medium (or vacuum), transporting energy without transporting matter. Energy cannot be created or destroyed, only transformed
