Question

If heating 3 g of a substance by 2 °C requires X joules of heat, how much heat will be needed to heat 9 g of the same substance by 4 °C?

Answer 1

q=mct, for this problem c is constant since the same object is being used. so first condition: x= 3 * 2 * c = 6c, second condition: y = 9 * 4 * c = 36c, where y is our answer. using these equations: y=6x , the answer is 6x
