Question

derive a formula for final temperature of mixture of samples​

Answer 1

Explanation:

Insert the values you recorded earlier into the equation and find the final temperature of the mixed water, T(final) = (50 g * 20 degrees + 20 g * 85 degrees) / (50 g + 20 g). Evaluate the equation to get T(final) = (1,000 + 1,700) / 70 = 2,700 / 70 = 38.57 degrees.
