Find the resultant temperature, when 50 gm substance at 50 degrees and 20gm substance at 20 degrees are mixed
Answers
Answer: Resultant temperature is 41.4 degree Celsius Explanation:
For the same substance specific heat will be same.so, from principle of method mixtures the formula for resultant temperature is given by...... T=(m1*s1*t1+m2*s2*t2)/(m1*s1+m2*s2) by substituting the given values we get, T=(50*s*50+20*s*20)/(50*s+20*s) where s=specific heat of substance on solving we get,T=(2500*s+400*s)/70*s which is equal to, T=2900*s/70*s=2900/70=41.4 degree Celsius
