<prompt> Na matla a bolokiloe ka hara sistimi e koetsoeng?nan  <response>: Instruction in English: Is energy conserved in a closed system? . Response in English: Yes, in a closed system, the law of conservation of energy states that the total amount of energy remains constant. This means that energy can neither be created nor destroyed, but it can be transformed from one form to another, or transferred from one object to another. So, the total amount of energy in a closed system always stays the same. . Response in Sesotho: E, tsamaisong e koetsoeng, molao oa paballo ea matla o bolela hore kakaretso ea matla e lula e le teng.
