Question

A chemistry student needs to calculate the heat required to raise the temperature of 25.0 g of water from 25°C to 60°C, given that the specific heat capacity of water is 4.18 J/g°C.

Answer 1

To calculate the heat required to raise the temperature of the water, we can use the formula:q = mcTwhere:q = heat required  Joules m = mass of the water  grams c = specific heat capacity of water  J/gC T = change in temperature  C Given:m = 25.0 gc = 4.18 J/gCInitial temperature  T1  = 25CFinal temperature  T2  = 60CFirst, we need to find the change in temperature  T :T = T2 - T1T = 60C - 25CT = 35CNow, we can plug the values into the formula:q =  25.0 g  4.18 J/gC  35C q = 25.0 * 4.18 * 35q = 3662.5 JSo, the heat required to raise the temperature of 25.0 g of water from 25C to 60C is 3662.5 Joules.
