If liquid in A and C are mixed, find temperature of mixture. (Thermodynamics Chapter)
Asked by jhajuhi19 | 18 Aug, 2021, 03:21: AM
Let T be be the final equilibrium temperature after mixing liquid-A and liquid-C

Heat energy gained by liquid-A = mA Cp ( T - 10 )

Heat energy lost by liquid-C = mC Cp ( 40 - T )

By conservation of energy Heat gain equals heat loss.

If we assume masses of liquids are equal and Specif heats are equal ( A and C are same liquid) , then by conservation of energy

mA Cp ( T - 10 ) = mC Cp ( 40 - T )

(T-10) = ( 40 - T )

from above expression we get , T = 25o C
