Question

40 gram of water at 60 degree centrigrade is poured into a vessel containing 50 gram water at 20 degree centrigrade . the final temparature recorded is 30 degree centrigrade. calculate the thermal capacity of the vessel

Answer 1

Let us compare the mSQ for both 

Which is the change in the product of mass x Specific heat x Change in temperature 

40 x 4.2 x 30=  50 x  thermal capacity of vessel x 10 

thermal capacity = 10.08 J / g C
