A 12 gram piece of metal is heated to 300 °C from 100 °C with 1120 Joules of energy. What is the specific heat of the metal?

The specific heat of the metal is 466.66 J/Kg°C.

Explanation:

Given,

mass = 12 gram = 0.012 Kg

T₁ = 300°C

T₂ = 100°C

ΔT = 200°C

Q = 1120 Joules.

The Specific heat of the substance can be calculated from the formula,

Q = (mass) (ΔT) (Cp)

Substituting the values,

1120 = (0.012)(200)(Cp)

Cp = 466.66 J/Kg°C.

Therefore, the specific heat of the metal is 466.66 J/Kg°C.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
