Duff states that equal masses of all substances have equal changes in internal energy when they have equal changes in temperature. Javan states that the change in internal energy is equal to a constant times the change in temperature for every ?T, no matter how large or how small ?T is, but that the constant is different for different substances. Which one, if either, is correct?
A. Neither, because the specific heat depends on the substance and may vary with temperature. B. Neither, because a change of state may involve release or absorption of latent heat. C. Neither because a substance may do work during a temperature change. D. All of the statements above are correct. E. Only statements (a) and (b) are correct.

Plane mirrors produce images which
A) are always smaller than the actual object. B) are always larger than the actual object. C) are always the same size as the actual object. D) could be smaller or the same size as the actual object, depending on the placement of the object. E) could be larger or the same size as the actual object, depending on the placement of the object.
