Astudent places 1.38 g of unknown metal at 99.68c into 60.50 g of water at 22.18c. the entire system reaches a uniform temperature at 31.68c. calculate the specific heat of the metal.

Explanation:

Hello,

Thermal equilibrium is reached when two substances at different temperatures are allowed to stabilize thermodynamically until a constant temperature is reached, in this case 31.68 °C, in this manner, the suitable equation to model this phenomena is:

Now, solving for the specific heat of the metal considering that the water's specific heat is and the given data, one obtains:

Best regards.
