    via the method of placing a metal block in boiling water so that the gain in internal energy of block = loss of internal energy of water.

    My Question tis:

    - Would it be more accurate if the water and metal reach the same final temperature are in thermal equlibrium? and why?

    To reduce errors you would ideally want
    *a large change in temperature for both water and block
    *an accurate measure of the final temperature of both
    *minimum loss of heat to the surroundings/container etc

    From the requirements of the 1st two points I don't see any advantage in the water and block not being at the same final temperature.
    It's relatively easy to measure the initial and final temperatures of the block if it is at room temperature at the start, and the same temperature as the water at the end.
