given specific heat, mass, and energy absorbed, how do i find rise in temperature?

specific heat = 400 j kg-1 K-1

mass = 50g

energy absorbed = 800J

    You have to use one simple formula : the energy formula: Q = m*c*(delta T)

    Q = heat energy

    m = mass

    c = specific heat

    delta t = change in temperature (= final - initial temp)

    So, before plugging in the numbers above, you need to get the correct units.

    Mass in kg will be .05kg

    Now plug in:

    800J=.05kg * 400JKg-1K-1 * delta T

    800J = 20JK-1 * delta T

    40K = delta T

    So, there was a difference of 40K in the temperature change.
