A 52.0 g of Copper (specific heat=0.0923cal/gC) at 25.0C is warmed by the addition of 299 calories of energy. find the final temperature of copper​

Respuesta :

Answer : The final temperature of the copper is, [tex]87.29^oC[/tex]

Solution :

Formula used :

[tex]Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})[/tex]

where,

Q = heat gained  = 299 cal

m = mass of copper = 52 g

c = specific heat of copper = [tex]0.0923cal/g^oC[/tex]      

[tex]\Delta T=\text{Change in temperature}[/tex] 

[tex]T_{final}[/tex] = final temperature = ?

[tex]T_{initial}[/tex] = initial temperature = [tex]25^oC[/tex]

Now put all the given values in the above formula, we get the final temperature of copper.

[tex]299cal=52g\times 0.0923cal/g^oC\times (T_{final}-25^oC)[/tex]

[tex]T_{final}=87.29^oC[/tex]

Therefore, the final temperature of the copper is, [tex]87.29^oC[/tex]
