I'm doing a lab using a calorimeter to find the changes in temperature of various metals in order to find the heat gained by water and specific heats.. In one of the questions it asks to calculate the amount of heat gained by the water from each metal (to determine the mass of the water, assume the density of water is 1.00g/mL.) Would I use the q=cmT formula?

Question

yes you would

But how would you find q without knowing c? @aaronq

thatonegirl_ · Answer

because the next question wants me to find the specific heat..

aaronq · Answer

you would have to use the formula twice.

once to find the heat transferred using the data for the water (mass, specific heat capacity and change in temperature)

then knowing that the heat absorbed by the water is the same as the heat lost by the metal,


    $\sf q_{water}=-q_{metal}$

use that to find the specific heat capacity of the metal (using the mass of the metal, the heat and the change in temperature)
