question 25

Multiple Choice

Fred states that equal masses of all substances have equal changes in internal energy when they have equal changes in temperature.

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 beginning with 'Neither' are correct.
