The specific heat of a metal is 3.76 cal/g°C. How much heat energy will it take to heat a 25.0 g cylinder of the metal from 21.5°C to 77.0°C?

Respuesta :

Answer:

The correct answer is "5217 Cal".

Explanation:

The given values are:

Specific heat,

c = 3.76 cal/g°C

Mass,

m = 25.0 g

Initial temperature,

T₁ = 21.5°C

Final temperature,

T₂ = 77.0°C

Now,

The heat energy will be:

⇒ [tex]Q=mc \Delta t[/tex]

On substituting the given values, we get

⇒     [tex]=25.0\times 3.76\times (77-21.5)[/tex]

⇒     [tex]=25\times 3.76\times 55.5[/tex]

⇒     [tex]=5217 \ Cal[/tex]
