[SOLVED] Heat Problem The question is: The only equations known are Q=mcΔT, and Q=ml Where Q= energy in joules. m=mass in kg, c= specific heat capacity [to 3 decimal places], ΔT= the change in temperature in either kelvin or Celsius, l= latent heat [also to 3 decimal places] However I am not limited to these equations, just expected to use them. Use of other equations is fine, so long as they are within reason. My train of thought was that, I need to find out and compare how many watts of heat will be absorbed by an identical body of mass over the same period of time at the two different temperatures, i just don't know how. I also think that this is one of those questions designed to trick, or at least make you really think. So I think that the short answer to the question is no, I just cant prove this right or wrong. I have tried taking a theoretical 1kg aluminium block and putting them into each of the temperatures resulting in these equations: 8.90e+3*14=124600 8.90e+3*28=249200 as 249200 is 2*124600 then it is twice as hot However I do not think this is right as these values are the amount of energy required to make this temperature change. Am I on the right track, or am I nowhere near the answer?
