The mass of the piece of copper, to the nearest whole number is 121 grams.
<u>Given the following data:</u>
- Specific heat capacity of copper = 0.385 J/g°C
- Initial temperature = 150.0°C
- Final temperature = 225.0°C
- Quantity of heat = 3,500 Joules
To calculate the mass of the piece of copper, to the nearest whole number:
Mathematically, quantity of heat is given by the formula;
<u>Where:</u>
- Q represents the quantity of heat.
- m represents the mass of an object.
- c represents the specific heat capacity.
- represents the change in temperature.
Making "m" the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Mass, m = 121.21 ≈ 121 grams
