Respuesta :

Q=mcdeltaT
Q=(750)(0.71)(160)
Q=85200j

Answer : The energy required will be, 85200 J

Solution :

Formula used :

[tex]Q=m\times c\times \Delta T[/tex]

where,

Q = heat required = ?

m = mass of graphite = 750 g

c = specific heat capacity of graphite = [tex]0.71J/g^oC[/tex]      

[tex]\Delta T=\text{Change in temperature}[/tex]  = [tex]160^oC[/tex]

Now put all the given values in the above formula, we get heat required.

[tex]Q=(750g)\times (0.71J/g^oC)\times (160^oC)=85200J[/tex]

Therefore, the energy required will be, 85200 J
