The specific heat capacity of this chunk of metal is equal to 0.32 J/g°C.
Given the following data:
- Quantity of energy = 400 Joules
- Initial temperature = 20°C
To determine the specific heat capacity of this chunk of metal:
The formula for quantity of heat.
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.
- ∅ represents the change in temperature.
Making c the subject of formula, we have:
[tex]c = \frac{Q}{m\theta}[/tex]
Substituting the given parameters into the formula, we have;
[tex]c = \frac{400}{250 \times (25-20)}\\\\c = \frac{400}{250 \times 5}\\\\c = \frac{400}{1250 }[/tex]
Specific heat, c = 0.32 J/g°C.
