    Solving Gauss Law Question: Q/(πR^4)

    Hi Im getting a slightly different answer to the one that is needed for the following question: 2) A positive charge Q is distributed throughout a spherical volume of radius R in vacuum. The charge density rho varies with the radius according to the linear law rho = a r. Show that the...

    Graduate Final state and temperature of 100 g steam at 150°C mixed with 1 kg water at 20°C

    Right, so now I have a ratio of the two dT's - between steam and water. Is that correct? I'm not sure how to use this though... Sorry if this is an elementary question and I'm just being slow!

    Graduate Final state and temperature of 100 g steam at 150°C mixed with 1 kg water at 20°C

    Well, for part b I may have an idea - whether its viable or not I'm not sure... My thoughts are that we know that the total energy of the system must remain constant. Therefore would it be possible to put the specific heat capacity equation of both cases equal to each other? I.e. the dQ would be...

    Graduate Final state and temperature of 100 g steam at 150°C mixed with 1 kg water at 20°C

    Hi Just wondering if I could have a bit of help on this question. Thanks in advance! 3) 100 g of steam at 150_C and 1 kg of water at 20_C are placed together inside an insulated volume. The specic heat of steam is 2.02x10^3J kg_1K_1, that of water is 4.19 x10^3 J kg_1K_1 and the latent...
