Question

Calculate the heat required to raise the temperature of a 50 g sample of water from 25°C to 85°C, given that the specific heat capacity of water is 4.184 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 is the heat required, m is the mass of the water, c is the specific heat capacity of water, and T is the change in temperature.Given:m = 50 gc = 4.184 J/gCInitial temperature  T1  = 25CFinal temperature  T2  = 85CFirst, we need to find the change in temperature  T :T = T2 - T1T = 85C - 25CT = 60CNow, we can calculate the heat required  q :q = mcTq =  50 g  4.184 J/gC  60C q = 12550.4 JSo, the heat required to raise the temperature of the 50 g sample of water from 25C to 85C is 12,550.4 J.
