A sphere of iron is heated up to 1000° C. Once heated, it has a radius of 1 cm.

Now suppose that we take the same 1000° C iron sphere and plunge it into a thermally insulated container with 1kg of 0° C ice. Calculate the temperature of the contents of the container once they have come to thermal equilibrium.

Additional information: • The density of iron is 7.874 g/cm3. Assume that this density does not depend on temperature. • The specific heat of iron is 462 J/kg K. • The latent heat of fusion for water is 3.33×105 J/kg. • The specific heat of liquid water is 4.19 J/g.

An iron alloy with a carbon content of 0.05% C is heated up to 912oC in an atmosphere that produces 1.20% C on the surface and thus is maintained for 24 hours. Calculate the carbon content at 0.05 cm below the surface if (a) iron is CC and (b) iron is CCC. Explain the difference. C-Fe bcc (Q= 20.900 cal/mol Do = 0,011 cm2/s ) C-Fefcc (Q= 32.900 cal/mol Do = 0,23 cm2/s ), ferror (0,0685)= 0,077, ferror(0,192) = 0,2139
