Open Lab Book Use your notes! Name? Last name, first name (i.e. Lonigro, Mr.) Fill in the blanks using the word bank. 1. energyis the ability to do work2. Heat energy, the energy of the motion of molecules, is called thermalenergy.3. electricalenergy comes from the flow of electrons.4. The total energy of motion and position of an object is known as mechanicalenergy.5. Changes to the nucleus of an atom, releasing energy by fusion or fission, is known as nuclearenergy.6. radiantenergy, sometimes known as light energy, is produced by electromagnetic waves.7. Energy stored in the bonds of molecules is called chemicalenergy. Label the chemical cell Use: wires, electrodes, electrolyte wires electrolyte electrodes What is another name for chemical cell? ion electrolyte battery generator Potential difference cause current to flow; another name for potential difference is _. electrode amps voltage electricity What is the importance of anelectrolytein a chemical cell? electrolytes act as wires as electrodes it is an acid it has extra electrons for the reaction According to class data, which combination of electrodes gave the highest voltage? magnesium and carbon magnesium and zinc copper and zinc zinc and carbon According to class data, which combination of electrons gave the lowest voltage? copper and zinc magnesium and zinc copper and magnesium zinc and zinc In the lemon lab, what was the electrolyte? carbon magnesium lemon juice Gatorade lemon Sort the circuit concepts Series Circuit 1 pathway removing a bulb stops current adding resistance decreases current Parallel Circuit 2+ pathways current still flows when a bulb is removed adding resistance increases current Both adding voltage increases current needs energy source Select the parallel circuit. Select the seriescircuit. Energy Flow Diagram Label the energy flow diagram. Use any of the MR. CENT types (mechanical, radiant, chemical, electrical, nuclear, thermal) chemical electrical radiant thermal
