Question

5. 5. A 3 gram sample of Zinc is heated with 100 J and then placed in a calorimeter. Thetemperature of the Water increases from 22 C to 25 C. What is the Specific Heat of

Answer 1

The Specific Heat of zinc = 11.11 J/g°C

Step-by-step explanation

Given:

Mass of the zinc sample, m = 3 g

Quantity of heat, Q = 100 J

Initial temperature, T₁ = 22 °C

Final temperature, T₂ = 25 °C

The change in temperature, ΔT = T₂ - T₁ = 25 °C - 22 °C = 3 °C

What to find:

The Specific Heat of zinc, c

Step-by-step solution:

The Specific Heat of zinc, c can be calculated using the formula given below.Q=m

`\begin{gathered} Q=mc\Delta T \\ \\ \Rightarrow c=(Q)/(m\Delta T) \end{gathered}`

Putting the values of the given parameters into the formula, we have;c

`c=\frac{100\text{ }J}{3g*3°C}=\frac{100J}{9\text{ }g°C}=11.11\text{ }J\text{/}g°C`

Hence, the Specific Heat of zinc is 11.11 J/g°C
