The mass of the piece of copper, to the nearest whole number is 121 grams.
Given the following data:
Specific heat capacity of copper = 0.385 J/g°CInitial temperature = 150.0°CFinal temperature = 225.0°CQuantity of heat = 3,500 JoulesTo calculate the mass of the piece of copper, to the nearest whole number:
Mathematically, quantity of heat is given by the formula;
[tex]Q = mc\theta[/tex]
Where:
Q represents the quantity of heat.m represents the mass of an object.c represents the specific heat capacity.[tex]\theta[/tex] represents the change in temperature.Making "m" the subject of formula, we have:
[tex]m = \frac{Q}{c\theta}[/tex]
Substituting the given parameters into the formula, we have;
[tex]m = \frac{3500}{0.385(225-150)}\\\\m = \frac{3500}{0.385 \times 75} \\\\m = \frac{3500}{28.875}[/tex]
Mass, m = 121.21 ≈ 121 grams
