Molao oa Pele oa Thermodynamics :
Melao ea matšoao :
Q e ntle haeba mocheso o eketsoa tsamaisong.
W e ntle haeba sistimi e sebetsa tikolohong
Q e mpe haeba mocheso o lokolloa ke sistimi
W e mpe haeba tikoloho e sebetsa tsamaisong
Liphetoho tsa eneji tsamaisong:
Matla a tsamaisong a eketseha ka li-Joules tse 500.
2. Li-joule tse 2000 tsa mocheso lia eketsoa tsamaisong 'me tikoloho e etsa mosebetsi oa li-joule tse 2500 tsamaisong. Phetoho ea matla a ka hare a sistimi ke…

Hoa tsebahala :
Mocheso (Q) = +2000 Joules
Mosebetsi (W) = -2500 Joule
E botsitsoe : liphetoho tsa matla tsamaisong
Jawab :
Matla a tsamaisong a eketseha ka li-Joules tse 4500.
3. Li-joule tse 2000 tsa mocheso li lokolloa tsamaisong, 'me tikoloho e etsa mosebetsi oa li-joule tse 3000 tsamaisong. Phetoho ea matla a ka hare a tsamaiso ke…

E botsitsoe : liphetoho tsa matla tsamaisong
Jawab :
Matla a tsamaisong a eketseha ka li-Joules tse 1000.
Qetello:
– Haeba sistimi e monya mocheso tikolohong, matla a tsamaisong aa eketseha.
– Haeba sistimi e lokolla mocheso tikolohong, matla a tsamaisong aa fokotseha.
– Haeba sistimi e sebetsa tikolohong, matla a tsamaisong aa fokotseha.
– Haeba tikoloho e sebetsa tsamaisong, matla a tsamaisong aa eketseha.
