3 Mienzaniso yemibvunzo pamusoro pemutemo wekutanga wethermodynamics
1. MaJoules matatu ekupisa anowedzerwa musystem, uye system inoita maJoules mazana maviri nemazana mashanu ekushanda munzvimbo dzakatenderedza. Kuchinja kwesimba remukati mesystem kuri…
Kukurukurirana
Zvinozivikanwa :
Kupisa (Q) = +3000 Joules
Basa (W) = +2500 Joules
Akabvunzwa : shanduko musimba remukati
Jawab :
Mutemo wekutanga weThermodynamics :
Mitemo yezviratidzo :
Q inoratidza kuti kupisa kwakawedzerwa musystem.
W inoratidza kuti system yacho inoshanda pane zvakatikomberedza.
Q haina kunaka kana kupisa kukaburitswa nesystem
W inoreva kuti hapana kana nzvimbo dzakatenderedza dzichishanda pasystem.
Kuchinja kwesimba muhurongwa:
Simba riri muhurongwa rinowedzera ne500 Joules.
2. MaJoules maviri ekupisa anowedzerwa kune imwe system uye nzvimbo dzakakomberedza dzinoita maJoules maviri ne500 ekushanda pane system. Kuchinja kwesimba remukati me system kuri…
Kukurukurirana
Zvinozivikanwa :
Kupisa (Q) = +2000 Joules
Basa (W) = -2500 Joules
Akabvunzwa : shanduko musimba muhurongwa
Jawab :
Simba riri muhurongwa rinowedzera ne4500 Joules.
3. MaJoules maviri ekupisa anoburitswa kubva musystem, uye nharaunda inoita maJoules matatu ekushanda pasystem. Kuchinja kwesimba remukati mesystem kuri…
Kukurukurirana
Zvinozivikanwa :
Kupisa (Q) = -2000 Joules
Basa (W) = -3000 Joules
Akabvunzwa : shanduko musimba muhurongwa
Jawab :
Simba riri muhurongwa rinowedzera ne1000 Joules.
Mhedziso:
– Kana sisitimu ikatora kupisa kubva munharaunda, simba riri musisitimu rinowedzera.
– Kana sisitimu ikaburitsa kupisa kunzvimbo yakapoteredza, simba riri musisitimu rinoderera.
- Kana sisitimu ikashanda pane zvakatipoteredza, simba riri musisitimu rinoderera.
- Kana nharaunda ikashanda pahurongwa, simba riri muhurongwa rinowedzera.
