Could you try the following question please: The temperature of a hot liquid in a container falls at a rate of 2 K per minute just before it begins to solidify. The temperature then remains steady for 20 minutes by which time all the liquid has all solidified. What is the ratio of the specific heat capacity of the liquid/specific latent heat of fusion A: 1/40, B: 1/10, C: 10, D: 40 Thanks

Please I have a question you said divide even though the question is asking for the rate of flow why didn't you divide the whole expression 'm×s.h.c×change in time ' by time since it's power

[@benjaminfranklin374]

Please i have a question you said divide both sides by 'time', why didn't you divide the whole expression on the otherside by 'time' not just the mass

u can write it as mcT/t if it makes more sense u get the same answer.
