Asquare steel bar of side length w = 0.18 m has a thermal conductivity of k = 15.3 j/(s⋅m⋅°c) and is l = 1.7 m long. once end is placed near a blowtorch so that the temperature is t1 = 81° c while the other end rests on a block of ice so that the temperature is a constant t2.
input an expression for the heat transferred to the cold end of the bar as a function of time, using a = w2 as the cross-sectional area of the bar. sig. gif? tid=2g65-6a-d8-4e-a33a-19217
how much energy, in joules, was conducted in 1 hour, assuming t2 = 0° c?
input an expression for the mass of the water melted in 1 hour using q1 from above and lf the latent heat of fusion. sig. gif? tid=2g65-6a-d8-4e-a33a-19217
