Three separate 3.5g blocks of al, cu, and fe at 25°c each absorb 0.505 kj of heat. which block reaches the highest temperature? the specific heats of al, cu, and fe are 0.900 j/g·°c, 0.385j/g·°c, and 0.444 j/g·°c, respectively.

    The energy can be shown as:

    Q = ms dT

    Whereas, m is the mass of block

    s is specific heat

    dT is change in temperature.

    Copper block having the lowest specific heat and thus having the higher change in temperature and therefore having the higher final temperature.
