Answer:
As the specific heat capacity for pure diamond is 0.5091 and it is different from the specific heat capacity found that is 0.2699
, the diamond sample is not pure.
Explanation:
1. As the problem says the equation that describes the amount of heat gained or lost by a substance is:
q=Cp*m*ΔT
where q is the amount of heat, Cp is the specific heat capacity, m is the mass and ΔT is the change in the temperature.
2. Solving for specific heat capacity:
3. Replacing values:
As the specific heat capacity for pure diamond is 0.5091 and it is different from the specific heat capacity found that is 0.2699
, the diamond sample is not pure.
