| December 16, 2020 | education
The amount of heat (Q) is found by the formula:
Q = cm (t2-t1)
Specific heat of water: c = 4200
To find the exact amount of heat, we will convert 500 grams into kilograms
500 (g) = 0.5 (kg)
Substitute the values and find Q
Q = 4200 * 0.5 * (45-15) = 63000 (J) = 63 (KJ)
Answer: Q = 63 (KJ)
