Question

What is the heat capacity of a 50 g copper block when heated from 25°C to 95°C, given that the specific heat capacity of copper is 0.385 J/g·°C? Calculate the amount of heat energy required to raise the temperature of the copper block by 70°C.

Answer 1

To calculate the amount of heat energy required to raise the temperature of the copper block by 70C, we can use the formula:q = mcTwhere q is the heat energy, m is the mass of the copper block, c is the specific heat capacity of copper, and T is the change in temperature.Given:m = 50 gc = 0.385 J/gCT = 95C - 25C = 70CNow, we can plug these values into the formula:q =  50 g    0.385 J/gC    70C q = 50  0.385  70q = 1347.5 JThe amount of heat energy required to raise the temperature of the 50 g copper block by 70C is 1347.5 J.
