Gas cloud 1 is likely to form a star. Gas cloud 2 is not. Based on this information, match the given conditions with each cloud. -Its temperature stays well
below 14 million Kelvin.
-Its volume shrinks and density
increases due to gravity.
-Its temperature surpasses
14 million Kelvin.
-It is spread out, with a greater volume and
lesser concentration of elements.
-Its hydrogen atoms shed their electrons.
-Its hydrogen atoms retain their electrons.

The first element on the periodic table of elements is carbon. a. true b. false

Hannah is writing a report on how albedo affects the global climate. she’s proofreading her passage for any factual errors. which sentence must hannah correct before submitting her report? earth receives energy from the sun. this energy drives many of the processes on earth, including its climate. some part of this energy is reflected by earth’s surface. we use the term albedo to describe the reflected energy. albedo of an object is the ratio of the reflected radiation to the total radiation reaching the object. a value of 0 means no energy is absorbed by the object, whereas a value of 1 means that all of the energy is absorbed. in this way, the albedo of an object can influence earth’s atmospheric temperature.

Check the correct box to describe the periodic trends in electronegativity. electronegativity across a period: decreases. increases. electronegativity down a group: decreases. increases.
