Final answer:
To calculate the heat necessary to change the temperature of a substance, use the formula q = mcΔT. In this case, the heat necessary to change the temperature of 3 kilograms of copper from 50°C to 60°C is 1155 J.
Step-by-step explanation:
To calculate the heat necessary to change the temperature of a substance, the formula q = mcΔT can be used.
Where:
q is the heat transfer
m is the mass of the substance
c is the specific heat capacity of the substance
ΔT is the change in temperature
In this case, the mass of the copper is 3 kilograms, the specific heat capacity of copper is approximately 38.5 J K-¹ mol-¹, and the change in temperature is 10°C.
By substituting the values into the formula, we can calculate the heat transfer:
q = (3 kg) × (38.5 J K-¹ mol-¹) × (10°C) = 1155 J K-¹ mol-¹
Therefore, the heat necessary to change the temperature of 3 kilograms of copper from 50°C to 60°C is 1155 J.
