Question

How many calories are required to raise the temperature of a 35.0 g sample of iron from 25 °C to 35 °C? Iron has a specific heat of 0.108 cal/g °C

Answer 1

For this question, you want to use q = m*c*(delta T), m = mass in grams, c = specific heat and delta T = change in temperature.

q = (35 g)*(0.108 cal/g °C)*(10 °C) = 37.8 calories

Hope this helps!!
