Réitigh 1Cal=4.18Jule

$$1 Cal = 4.18 Jule$$

Réitigh do C.

$$\left\{\begin{matrix}C=\frac{209eJu}{50a}\text{, }&a\neq 0\\C\in \mathrm{R}\text{, }&l=0\text{ or }\left(J=0\text{ and }a=0\right)\text{ or }\left(u=0\text{ and }a=0\right)\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Athordaigh na téarmaí.

$$Cal=4.18eJlu$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$alC=\frac{209eJlu}{50}$$

Roinn an dá thaobh faoi al.

$$\frac{alC}{al}=\frac{209eJlu}{50al}$$

Má roinntear é faoi al cuirtear an iolrúchán faoi al ar ceal.

$$C=\frac{209eJlu}{50al}$$

Roinn \frac{209Jule}{50} faoi al.

$$C=\frac{209eJu}{50a}$$

Réitigh do J.

$$\left\{\begin{matrix}J=\frac{50Ca}{209eu}\text{, }&u\neq 0\\J\in \mathrm{R}\text{, }&l=0\text{ or }\left(C=0\text{ and }u=0\right)\text{ or }\left(a=0\text{ and }u=0\right)\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Athraigh na taobhanna ionas go mbeidh na téarmaí inathraitheacha ar fad ar an taobh clé.

$$4.18Jule=1Cal$$

Athordaigh na téarmaí.

$$4.18eJlu=Cal$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$\frac{209elu}{50}J=Cal$$

Roinn an dá thaobh faoi 4.18ule.

$$\frac{50\times \frac{209elu}{50}J}{209elu}=\frac{50Cal}{209elu}$$

Má roinntear é faoi 4.18ule cuirtear an iolrúchán faoi 4.18ule ar ceal.

$$J=\frac{50Cal}{209elu}$$

Roinn Cal faoi 4.18ule.

$$J=\frac{50Ca}{209eu}$$
