Answer:
Iron
Explanation:
Heat released by the metal sample will be equivalent to the heat absorbed by water.
But heat = mass × specific heat capacity × temperature change
Thus;
Heat released by the metal;
= 45.9 g × c ×(95.2 -24.5) , where c is the specific heat capacity of the metal
= 3245.13c joules
Heat absorbed by water;
= 120 g × 4.18 J/g°C × (24.5-21.6)
= 1454.64 joules
Therefore;
3245.13c joules = 1454.64 joules
c = 1454.64/3245.13
= 0.448 J/g°C
The specific heat capacity of the metal sample is 0.448 J/g°C. The metal use is most likely, Iron.
