How much heat is needed to heat 300 g of zinc from 10 to 30 degrees Celsius?
| November 23, 2020 | education
The formula for the amount of heat for heating: Q = mc (t2-t1), – where m is the mass of zinc, c is the specific heat capacity of zinc, t2-t1 is the temperature change
We substitute these values into the formula: Q = 0.3 kg * 400 J / (kg * ° C) * (30 ° C-10 ° C) = 2400 J
Answer: 2400J
