Question

water of mass 80g and temperature 45°C is mixed with water of mass 20g and temperature 30°C , find the maximum temperature of the mixture​

Answer 1

Answer:

T(final) = 42°C

Explanation:

Q(heat) lost by one substance will be equal to Q gained by the other. In this case both substances are water. Thus their c(specific heat capacity) gets cancelled.

Equating formula for Q( = mc∆T) we'll reach the final solution.
