2 liters of water at 80.c is found into a plastic bucket containing 10 liters of water at 20.c what is the final temperature of water ( density of water 1kg/litre) (neglect the heat gained by bucket and specific heat capacity of water = 1cal/gm.c

  • physics - ,

    m1•c(t1-t) = m1•c(t-t2)
    m=D•V
    D•V1(t1-t) = D•V2(t-t2)
    2(t1-t) = 10(t-t2)
    t1+5t2=6t
    t=30ºC
