What is the temperature change on a 75.0 gram sample of mercury if 480.0 cal of heat are added to it? The specific heat of mercury = 0.033 cal/g C

Respuesta :

Answer:

[tex]\Delta T=194^oC[/tex]

Explanation:

Hello,

In this case, the relationship between the mass, heat, temperature and heat capacity id given by:

[tex]Q=mCp\Delta T[/tex]

In such a way, the temperature change results:

[tex]\Delta T=\frac{Q}{mCp}=\frac{480.0cal}{75.0g*0.033cal/(g^oC)} \\\\\Delta T=194^oC[/tex]

Clearly it is a positive change which means the temperature increases as heat is added.

Regards.
