Open. Open clusters are young, and therefore consist of the young Population I stars. Population I stars have the highest metallic content. Based on what you learned about the Big Bang, how stars our formed, and supernovas, this makes sense. The earliest stars would have been formed entirely of hydrogen and helium. When they blew up in supernovas, they would have created and left behind heavier elements--metals. New stars that formed in these clouds of gas from the aftermath of the supernova would have higher metallic content, and when they explode, they would leave behind an even richer cloud of gas for subsequently born stars. In other words, each generation of stars would be more metallic than the previous one. Our sun is a population I star. Keep in mind that the population category of a star only relates to its age and metallicity; it doesn't matter what population a star is in, it still goes through the exact same process of formation, evolution and death you learned about. The Electromagnetic Spectrum, Kepler's Laws of Motion and Other Important Discoveries _____________ and helium, the most abundant elements in stars in the solar neighborhood, are also the most abundant constituents of the stars in all kinds of clusters. ailed Explanation: Hydrogen. Open clusters have a comparable element content to that of the sun. However, globular clusters have a much lower element content. Differences in chemical composition are related to differences in stellar population. The ________ and the vast majority of other stars are stable and in a steady state, neither expanding nor contracting. Explanation: Sun. This state of stability is called a condition of equilibrium. All the forces within it are balanced so that at each point within the star, the temperature, pressure, density, etc. are maintained at constant values. A balance between the weights of various layers and the pressures that support them is called ______________ equilibrium. Explanation: Hydrostatic. This shows that the surface and internal temperatures of stable stars is balanced. If the internal gas pressure in a star were not great enough to balance the weight of its outer parts, the star would collapse and contract until the gas pressure inside built up to the point where it could support the star.

The ____________ gas law provides a mathematical relation between the pressure, density, and temperature of an ideal gas and states that the pressure is proportional to the product of the density and temperature of the gas. : Perfect. The gases in most stars closely approximate an ideal gas and must obey this law. The pressure is proportional to the density and temperature of the gas. Energy associated with the motion of the molecules in a star is called stellar _____________ energy. Explanation:
