You are right. My mistake for no mentioning however if you look at the units of c (kj/ kg k) it doesn’t matter if we use kj and kg or j and g

sir at 10:32 you did -2952/40X2.46

c=2.46 is in KJ, but q=-2952 is in J, i was wondering wouldn't we divide -2952 by 1000 to make sure both are in KJ? i thought we need to keep the units the same when calculating

hi sir i wanted to ask would it be better to word the assumption for the mass of water as that being equal to the volume of the water in calorimetry calculations? i've seen some questions pop up like this here and there

popemup patch update: at 11:54 when doing n=cv calculation you did it ÷100 and not 1000 (expect more potential patch updates LOL)
