The diagram shows a heating curve for a substance. A graph titled heating curve of Substance It shows heat added in joules on the x-axis, and temperature in degrees celsius on the y-axis on a scale of 0 to 100. The graph has a diagonal line from negative 5 degrees up to zero degrees labeled U. A horizontal line segment at zero degrees labeled V. A diagonal line segment from zero degrees up to 120 degrees labeled W. A horizontal line segment at 120 degrees labeled X and then another diagonal segment labeled Y.

Which segment shows the substance changing from a gas to a liquid?

Neutrons are placed in a magnetic field with magnitude 2.30 t. part a part complete what is the energy difference between the states with the nuclear spin angular momentum components parallel and antiparallel to the field? δe δ e = 2.77×10−7 ev previous answers correct part b part complete which state is lower in energy: the one with its spin component parallel to the field or the one with its spin component antiparallel to the field? which state is lower in energy: the one with its spin component parallel to the field or the one with its spin component antiparallel to the field? parallel antiparallel previous answers correct part c part complete how do your results compare with the energy states for a proton in the same field (δe=4.05×10−7ev)? how do your results compare with the energy states for a proton in the same field this result is smaller than but comparable to that found in the example for protons. this result is greater than but comparable to that found in the example for protons. previous answers correct part d the neutrons can make transitions from one of these states to the other by emitting or absorbing a photon with energy equal to the energy difference of the two states. find the frequency of such a photon. f f = mhz previous answersrequest answer incorrect; try again; 5 attempts remaining
