a 22.44 g sample of metal absorbs 180.8 J of hear , upon which the temprature of the sample increases from 21.1 °C to 45.0 °C . what is the specific heat of that metal

Respuesta :

Answer:

The specific heat of the metal is [tex]0.337\ J/g^{\circ} C[/tex].

Explanation:

We have,

Mass of sample is 22.44 g

It absorbs 180.8 J of heat.

The temperature of the sample increases from 21.1 °C to 45.0 °C

Initial temperature is 21.1 °C and final is 45.0 °C.

Heat absorbed in terms of specific heat is given by :

[tex]Q=mc\Delta T\\\\c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{180.8}{22.44\times (45-21.1)}\\\\c=0.337\ J/g^{\circ} C[/tex]

So, the specific heat of the metal is [tex]0.337\ J/g^{\circ} C[/tex].
