Question

A physics student performed an experiment by tak-
ing a beaker with 1 l of water at 30°C and dropping
an iron sphere with temperature 90°C in it. After
sometime, student measured their equilibrium tem-
perature as 48°C. If the density of iron sphere is 7870
kg m-3, then find the volume of the iron sphere.
Specific heat of iron is 0.110 cal g-1°C-1,​

Answer 1
