Homework Help: Latent heat

  1. Feb 7, 2006 #1
    how do you slove latent heat problems?

    also is there a easier way to slove thermodyamics problem?

    explain in a way a way that a 9th grader like me can understand.

    thanks

    i need to know the Phase change of objects and how to caculate the Joules of energy needed for the changes.

    Generally, at that level, such problems ask for final temperature and you get the latent heat from a table. But perhaps you could be more specific....?

    yeah

    first off
    "also is there a easier way to slove thermodyamics problem?"
    simply put.....no

    you solve them by using the equation

    Q=cm(delta)T

    i would like to know more about the heat exchange in mixtures and
    example would be like:

    How much heat energy is required to change?
    a) 2.0kg of ice at 0 C to water at 0 C?

    b) 500g of water at 100 C to steam at 100 C?
