Question

Calculate the specific heat of an unknown metal if it took 58.1 J to increase the temperature of 89.4 g of the metal from 23.4°C to 25.5°C.

Answer 1

`c=0.309\ J/g^(\circ) C`

Step-by-step explanation:

The increase in heat, Q = 58.1 J

Mass, m = 89.4 g

The temperature increases from 23.4°C to 25.5°C. We need to find the specific heat of an unknown metal.

We know that the increase in heat is given by :

`Q=mc\Delta T\\\\c=(Q)/(m\Delta T)\\\\c=(58.1)/(89.4* (25.5-23.4))\\\\c=0.309\ J/g^(\circ) C`

So, the specific heat of an unknown metal is equal to
`0.309\ J/g^(\circ) C`.
