15. which of the following is accurate when discussing specific heat?

a. specific heat values for solids will never vary for different ranges of temperature.
b. the specific heat of a gas can be measured at constant volume only.
c. specific heat values for liquids will never vary for different ranges of temperature.
d. the specific heat of a gas may be measured at constant pressure

Which accounts for an increase in the temperature of a gas that is kept a constant volume

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop

Which of the following conditions lead you to see an absorption line spectrum from a cloud of gas in interstellar space? the cloud is extremely hot. the cloud is visible primarily because it reflects light from nearby stars. the cloud is cool and lies between you and a hot star. the cloud is cool and very dense, so that you cannot see any objects that lie behind it.
