I do believe all of these but core elements can be determined by spectroscopy which includes the use of electromagnetic radiation. Both the surface and core temperature can be measured using light. Surface elements can be found because the absorption lines of different elements in the spectra of the star, but I haven't heard anything about using spectral analysis for core elements.

Nathan hypothesized that if the temperature of liquid water increased, the density would decrease because the volume would increase. He collected the data in the table below.

How does Nathan’s hypothesis lead to new investigations
