Izibonelo ezi-3 zemibuzo ngomthetho wokuqala we-thermodynamics
1. Ama-Joules angu-3000 okushisa ayengezwa ohlelweni, futhi uhlelo lwenza ama-Joules angu-2500 omsebenzi endaweni ezungezile. Ushintsho lwamandla angaphakathi ohlelweni…
Ingxoxo
I-Diketahui :
Ukushisa (Q) = +3000 amaJoules
Umsebenzi (W) = +2500 amaJoules
Kubuziwe : izinguquko emandleni angaphakathi
Jawab :
Umthetho Wokuqala We-Thermodynamics :
Imithetho yokusayina :
U-Q ulungile uma kufakwa ukushisa ohlelweni.
U-W ulungile uma uhlelo lusebenza endaweni ezungezile
U-Q ungemuhle uma ukushisa kukhishwa uhlelo
U-W ungemuhle uma indawo ezungezile isebenza ohlelweni
Izinguquko zamandla ohlelweni:
Amandla ohlelweni anda ngama-Joules angu-500.
2. Ama-Joules angu-2000 okushisa ayengezwa ohlelweni kanti indawo ezungezile yenza umsebenzi wama-Joules angu-2500 ohlelweni. Ushintsho lwamandla angaphakathi ohlelweni…
Ingxoxo
I-Diketahui :
Ukushisa (Q) = +2000 amaJoules
Umsebenzi (W) = -2500 amaJoules
Kubuziwe : izinguquko zamandla ohlelweni
Jawab :
Amandla ohlelweni anda ngama-Joules angu-4500.
3. Ama-Joules angu-2000 okushisa akhishwa ohlelweni, kanti indawo ezungezile yenza umsebenzi wama-Joules angu-3000 ohlelweni. Ushintsho lwamandla angaphakathi ohlelweni…
Ingxoxo
I-Diketahui :
Ukushisa (Q) = -2000 Joules
Umsebenzi (W) = -3000 amaJoules
Kubuziwe : izinguquko zamandla ohlelweni
Jawab :
Amandla ohlelweni anda ngama-Joules angu-1000.
Isiphetho:
– Uma uhlelo lumunca ukushisa okuvela endaweni ezungezile, amandla ohlelweni ayakhula.
– Uma uhlelo lukhipha ukushisa endaweni ezungezile, amandla ohlelweni ayancipha.
– Uma uhlelo lusebenza endaweni ezungezile, amandla ohlelweni ayancipha.
– Uma indawo iyasebenza ohlelweni, amandla ohlelweni ayakhula.
