An ice cube of mass 0.1 kg of 0^@Cis placed in an isolated container which is 227^@CThe specific heat capacity S of the container varies with temperature T according to the empirical relation S = A+BT, where A = 100 cal/kg -K and B = 2xx10^(2) cal//kg - K^(-2).If the final temperature of the container is 27^@C Latent heat of fusion of water is 8x10^(4) cal/kg, specific heat of water is 10^(-3)cal/kg-k. If the coefficient of lincar expansion for ice varies with temperature as alpha (T) . If L_0is initial length of the edge of ice cube at T, and the temperature of ice changed from T_0toT(T_(0) gt T)then:

Answer»

`L=L_0int_(T_0)^(T)ALPHA(T)DT`
`L=L_0[1+int_(T_0)^(T)alpha(T)dT]`
`L=L_0[1-int_(T_0)^(T)alpha(T)dT]`
`L GT L_0`
