In 1906, a 600 g diamond was found at the Premier Mine in South Africa- the world's largest uncut diamond. Suppose the diamond's

temperature changed by 2 as it was cut. If the specific heat capacity of diamond is 710 J/gt, how much energy was transferred to the

diamond by the heat?

O A 0.59)

B. 2.36

OC 426,000 ]

OD 852,000)

The amount of energy transferred to the diamond while being cut is thus  Q = 852000 J

Explanation:

Since quantity of heat transferred Q = mcΔθ where m = mass of substance , c = specific heat capacity of substance and Δθ = temperature change.

Now, given that for diamond, m = mass of diamond = 600 g, c = specific heat capacity of diamond = 710 J/g°C and Δθ = temperature change = 2 °C.

So, the amount of energy transferred to the diamond while being cut is thus

Q = mcΔθ

Q = 600 g × 710 J/g°C × 2 °C

Q = 852000 J

So, the amount of energy transferred to the diamond while being cut is thus  Q = 852000 J
