Physics – Thermodynamics Exam with verified detailed answers
|| || || || || || ||
conduction - ✔✔direct transfer of energy from molecule to molecule
|| || || || || || || || ||
convection - ✔✔transfer of heat by physical motion of heated material (only with gas and
|| || || || || || || || || || || || || || ||
liquid)
radiation - ✔✔transfer of energy by electromagnetic waves
|| || || || || || ||
first law of thermodynamics - ✔✔conservation of energy
|| || || || || || ||
the change in the total internal energy of a system is equal to the amount of energy
|| || || || || || || || || || || || || || || || ||
transferred in the form of heat to the system, minus the amount of energy transferred from
|| || || || || || || || || || || || || || || ||
the system in the form of work
|| || || || || ||
second law of thermodynamics - ✔✔entropy of the universe is always increasing except at
|| || || || || || || || || || || || || ||
absolute zero ||
energy spontaneously disperses from being localized to becoming spread out of it is not
|| || || || || || || || || || || || || ||
hindered from doing so || || ||
third law of thermodynamics - ✔✔a system will asymptotically approach an entropy
|| || || || || || || || || || || ||
minimum as it asymptotically approaches absolute zero
|| || || || || ||
thermodynamics - ✔✔study of the flow of energy in the universe, as that flow relates to || || || || || || || || || || || || || || || ||
work, heat, the different forms of energy, and entropy
