When a 57-gram piece of aluminum at 100oC is placed in water, it loses 735 calories of heat while cooling to 30oC. Calculate the specific health capacity of the aluminum

Respuesta :

Answer:

specific heat capacity of aluminium is 0.184 Calroie/ gram-K.

Explanation:

As we know that heat transferred to a given material to change its temperature is given as

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

here we know

Q = heat given = 735 calorie

m = mass = 57 gram

initial temperature = 100 degree C

final temperature = 30 degree C

now by above formula we will have

[tex]735 = 57(s)(100 - 30)[/tex]

[tex]s = 0.184 \frac{cal}{g-K}[/tex]
