sound waves in air and water are longitudinal. Their disturbances are periodic variations in pressure that are transmitted in fluids. Figure 13.5 the wave on a guitar string is transverse
The specific heat capacity of this chunk of metal is equal to 0.32 J/g°C.
<u>Given the following data:</u>
- Quantity of energy = 400 Joules
- Initial temperature = 20°C
To determine the specific heat capacity of this chunk of metal:
<h3>
The formula for quantity of heat.</h3>
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 c the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Specific heat, c = 0.32 J/g°C.
