Sir is this question highly expected for tommorrow's paper ??

[@rifannizar8629]

sir i have a doubt
in the equation Q=mc(temp change)
is m only the mass of water and liquids that have same density as water
or the substances added like for example I have a solution of 20cm^3 and I add 4g of FB5( salt Na2A.5H2O)
then do I add the mass of FB5 also to get Q=(20+4)*4.18*(temp change)
or would I just do Q=20*4.18*(temp change)
please answers I have my p3 exam tomorrow
