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°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;

[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 = 121.21121 grams
