    Lol you're right on that :)

    Speed of sound, frames of reference

    360...? Because the sound is towards C so the speed will 'seem' faster?

    35 degrees Edit: Misread what you said lol, final temperature of the copper as it sits in the water bath? 843?

    Thermal physics; specific heat capacity

    3.78*10^4J... 3.78*10^4J=0.12*390*change in temperature so change in temperature = 808? This is where I get stuck on...I don't know how to find the final temperature

    Thermal physics; specific heat capacity

    Homework Statement In an experiment to measure the temperature of the flame of a Bunsen burner, a lump of copper of mass 0.12 kg is heated in the flame for several minutes. The copper is then transferred quickly to a beaker, of negligible heat capacity, containing 0.45 kg of water, and the...
