To calculate the heat capacity of water, we can use the formula:q = mcTwhere q is the heat energy in joules , m is the mass of the water in grams , c is the specific heat capacity of water in J/gC , and T is the change in temperature in C .We are given the following information:- Mass of water m = 10 grams- Heat energy q = 500 joules- Change in temperature T = 5CWe need to find the specific heat capacity c of water. Rearranging the formula to solve for c, we get:c = q / mT Now, we can plug in the given values:c = 500 J / 10 g 5C c = 500 J / 50 gCc = 10 J/gCThe heat capacity of 10 grams of water at 25C is 10 J/gC.
