4 Ukushisa okucashile Ukushisa kokuhlanganiswa Ukushisa kokuhwamuka - Izinkinga Nezixazululo
1. Bala inani lokushisa elifakwe ku-1 gram yegolide ukushintsha isigaba kusuka kokuqinile kuya kokuketshezi. Ukushisa kokuhlanganiswa kwegolide kungu-64.5 x 10 3 J/kg.
Kwaziwa:
Isisindo (m) = 1 gram = 1 x 10 -3 kg
Ukushisa kokuhlanganiswa (L F ) = 64.5 x 10 3 J/kg
Okufunwayo: Ukushisa (Q)
Isixazululo:
Q = m L F
Q = (1 x 10 -3 kg)(64.5 x 10 3 J/kg)
Q = 64.5 Joule

2. Bala inani lokushisa elikhishwa yi-1 gram ye-mercury ukushintsha isigaba kusuka koketshezi kuya kokuqinile. Ukushisa kokuhlanganiswa kwe-mercury kungu-11.8 x 10 3 J/kg.
Kwaziwa:
Isisindo (m) = 1 gram = 1 x 10 -3 kg
Ukushisa kokuhlanganiswa (L F ) = 11.8 x 10 3 J/kg
Okufunwayo: Ukushisa (Q)
Isixazululo:
Q = m L F
Q = (1 x 10 -3 kg)(11.8 x 10 3 J/kg)
Q = 11.8 Joule
3. Thola inani lokushisa elimuncwa amanzi angu-1 kg ukushintsha isigaba kusuka koketshezi kuya komusi (umusi). Ukushisa kokuhwamuka kwamanzi = 2256 x 10 3 J/kg
Kwaziwa:
Isisindo (m) = 1 kg
Ukushisa kokuhwamuka (L V ) = 2256 x 10 3 J/kg
Okufunwayo: Ukushisa (Q)
Isixazululo:
Q = m L V
Q = (1 kg)( 2256 x 10 3 J/kg)
Q = 2256 x 10 3 amaJoules

4. Nquma inani lokushisa elikhishwa yi-nitrogen ukushintsha isigaba kusuka kumusi kuya koketshezi. Ukushisa kokuhwamuka kwe-nitrogen = 200 x 10 3 J/kg
Kwaziwa:
Isisindo (m) = 1 gram = 1 x 10 -3 kg
Ukushisa kokuhwamuka (L V ) = 200 x 10 3 J/kg
Kwaziwa: Ukushisa (Q)
Isixazululo:
Q = m L V
Q = (1 x 10 -3 kg)( 200 x 10 3 J/kg)
Q = 200 Joule
- Ukuguqula izikali zokushisa
- Ukunwetshwa komugqa
- Ukwandiswa kwendawo
- Ukunwetshwa kwevolumu
- Heat
- Okulingana nokushisa okwenziwe ngomshini
- Ukushisa okukhethekile kanye nomthamo wokushisa
- Ukushisa okucashile, ukushisa kokuhlanganiswa, ukushisa kokushisa komhwamuko
- Ukonga amandla okudlulisa ukushisa
