    Q= m.c. (Tf-Ti)
    -2455 cal= 468g. C.(30ºC-70ºC)
    -2455 cal= 468g. C. (-50)
    -2455 cal= -23400 cal/gºC . C
    C= -2455 cal÷-23400 cal/gºC
    C= 0,105 cal/g.ºC

    I agree. I am 65years old and expect to see things get worse before they get better for the Palestinians because of the US support for Israel. The lobby is so powerful that it will probably keep Anthony wiener in office in spite of his nasty tweets.
