The Common Core is a set of high-quality academic standards in mathematics and English language arts/literacy (ELA).ecognizing the value and need for consistent learning goals across states, in 2009 the state school chiefs and governors that comprise CCSSO and the NGA Center coordinated a state-led effort to develop the Common Core State Standards.
Spectral Types and Surface Temperatures. Spectral types are a measure of the surface temperatures of stars and are letter designations: O, B, A, F, G, K, and M. Type O stars have the highest surface temperatures and can be as hot as 30,000 Kelvins. On the other extreme, type M stars have the lowest surface temperatures and can be as cool as 3,000 K. Hertzsprung-Russell Diagram The most significant feature of the HR Diagram is that the stars are not distributed in it at random (showing any combinations of absolute magnitudes and spectral types), but rather group themselves only into certain parts or regions of the diagram thus forming several groups.
Venus has the highest surface temperature. Although Mercury is closer, Venus holds the suns heat in much more efficiently with its thick Carbon Dioxide atmosphere. Although Mercury is the closest planet to the sun, it is only the second hottest planet after Venus. Venus gets hotter as the thick carbon Dioxide atmosphere holds the heat more effectively, while Mercury has no atmosphere. Surface temperatures on Venus average 735 Kelvin or 460 Â°C. Venus has the highest surface temperature.
