Know the principle of conservation of energy and apply it to energy transfers - ANSWER-Energy cannot be created nor destroyed, it however be converted to a different form. Law of Conservation of Energy (also known as First Law of Thermodynamics) - ANSWER-in the middle of the 19th century, it was proposed by the English and German scientists that the total energy in the universe is constant. Essentially, energy cannot be created nor destroyed. Energy can, however, by converted from one form to...

First Law of Thermodynamics - ANSWER-energy can be transferred and transformed, but it cannot be created or destroyed the total internal energy of a system is equal to the amount of heat added minus the work done on the system First Law of Thermodynamics Equation - ANSWER-delta U=Q-W Q= heat energy W=work done on the system delta U= change in the system's internal energy Change in internal energy (equation) - ANSWER-ΔU decreasing temp= negative increasing temp = positive H...

conduction - ANSWER-The transfer of thermal energy with no overall transfer of matter is called ___________________. In conduction, thermal energy is transferred by collisions between particles, and there are fewer collisions among particles in a gas than in a liquid or a solid. - ANSWER-Why is conduction slower in gases than in liquids and solids? true - ANSWER-Is the following sentence true or false? Conduction is faster inmetals than in other solids because metals have free electrons th...
