Please show each step: Consider a mixture of 100 grams of water at

25 ° C with 75 grams of water at 40 ° C. Calculate the final temperature of the sample.

2 answers

the warmer water looses heat, while the cooler water gains heat

let t equal the final temperature

100 (t - 25) = 75 (40 - t)

solve for t

I'm not too good at this, would it be 31° C?
