Question

What is the heat required to raise the temperature of 75 g of water from 25°C to 90°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 a substance, we can use the formula:q = mcTwhere q is the heat required, m is the mass of the substance, c is the specific heat capacity, and T is the change in temperature.In this case, we have:m = 75 g  mass of water c = 4.18 J/gC  specific heat capacity of water T = 90C - 25C = 65C  change in temperature Now, we can plug these values into the formula:q =  75 g    4.18 J/gC    65C q = 20392.5 JSo, the heat required to raise the temperature of 75 g of water from 25C to 90C is 20,392.5 Joules.
