Question

Compared to a molecule with fewer degrees of freedom, of freedom, a molecule that has more degrees of freedom should require the same amount of added energy to increase its temperature. requires less added energy to increase its temperature. has a lower specific heat. has a larger heat of fusion. should require more added energy to increase its temperature. Two objects that have different masses, sizes, and temperatures come into close contact with each other. Thermal energy is transferred from the larger object to the smaller object. from the object that has more mass to the object that has less mass. from the object that has the higher temperature to the object that has lower temperature. from the object that has lower temperature to the object that has higher temperature. back and forth between the two objects until they come to equilibrium. Which of the following would generally increase the latent heat of a substance? A more dense aterial Tighter bonds between molecules A larger number of molecules per unit volumee All of the above None of the above

Explanation / Answer

Question 6: Option E: Specific heat (C) of a molecule is directly proportional to degrees of freedom. When specific heat increases, the energy required to raise the temperature by 1oC also increases.

Question 7: Option C: Thermal Energy is transferred from the object which has higher temp to the body with lower temp till they reach equilibrium

Question 8: Option D: Latent heat depends on the number and strength of bonds or force pairs. The number of bonds is proportional to the number of molecules per unit volume and thus to the density.
