# 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.
