    What is heat capacity in terms of its SI units? Find that and link it to the gradient of the graph and comare

    Answer would be A. This as q=mc(delta T) So compare it to y=mx+c, m=mass*specific heat capacity; mass is constant so the one with the steeper gradient has the largest specific heat capacity

    It's actually C. Look at the axes, the gradient is 1 over heat capacity not heat capacity, so highest heat cap would be smallest gradient which is C.

    I got C, but my physics teacher thought A, still not sure which answer is correct

    I believe C is correct.

    Specific Heat Capacity itself is the amount of energy required to increase the temperature of 1 kilogram of a substance by 1 degree.

    With a constant amount of energy (relatively between A,B and C), C experiences the smallest temperature increase. Thereby, it takes more energy to increase the temperature of 1 kilogram of C by 1 degree.

    It is 100% C, I think your teacher just made the expected error with the axes, its meant to trip you up.

    Ask him the question again and tell him to look closely at the axes
