Correct answer is C
Heat lost = heat gained
moCo\(\theta\)o = mwCw\(\theta\)w
100 x Co x (25 - 9) = 150 x Cw x (15 - 9)
\(\frac{C_w}{C_w}\) = 0.56
temperature is a measure of the average kinetic energy of the molecules of a substance
heat is a measure of the total kinetic energy of the molecules in a system
