An unknown metal has a mass of 86.8 g. When 5040 J of heat are added to the sample, the sample temperature changes by 64.7 ∘ C . Calculate the specific heat of the unknown metal.

The specific heat of the unknown metal is

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q = Heat absorbed= Joules

m= mass of substance = 86.8 g

c = specific heat capacity = ?

Initial temperature of the water =

Final temperature of the water =

Change in temperature ,

Putting in the values, we get:

The specific heat of the unknown metal is

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
