A 19-g piece of metal absorbs 186.75 joules of heat energy, and its temperature changes from 35°C to 175°C. Calculate the specifi heat capacity of the metal

Respuesta :

Answer:

0.0702J/g°C the specific heat capacity of the metal.

Explanation:m

[tex]Q=m\times c\times \Delta T=m\times c\times (T_{2}-T_{1})[/tex]

where,

Q = heat absorbed by metal = 186.75 J

[tex]m_1[/tex] = Mass of metal= 19 g

[tex]T_1[/tex] = Initial  temperature of metal = [tex]35^oC[/tex]

[tex]T_2[/tex] =Final  temperature of metal = [tex]175^oC[/tex]

[tex]c[/tex] = specific heat of metal= ?

[tex]186.75 J=19 g\times c\times (175^oC-35^oC)[/tex]

[tex]c=\frac{186.75 J}{19 g\times (175^oC-35^oC)}[/tex]

[tex]c=0.0702J/g^oC[/tex]

0.0702J/g°C the specific heat capacity of the metal.
