How can astronomers observe through these dusty clouds? What can possibly happen in these clouds in millions of years?
If our Sun were surrounded by a cloud of gas, would this cloud
be an emission nebula? Why or why not?
Presumably, the collapse causes the density of the cloud to increase. How does this
stop particles from reaching escape speed?
increase the temperature of the cloud

- The dimensions of the large cumulonimbus cloud pictured areroughly 12 kilometers high, 8 kilometers wide, and 8 kilometerslong. Assume that the droplets in every 1 cubic meter of the cloudtotal 0.5 cubic centimeter of water. How much liquid water doesthe cloud contain? How many gallons does it contain (3785 cm =1 gallon)?arrow_forwardLook at Figure 19-9. Rising from Earths surface to the cloud layer shown, does the temperature increase, decrease, or stay the same? How about from the clouds to the ozone layer? At about what altitude does the temperature change most abruptly, almost 400F in 30 km?arrow_forwardA) A typical dust grain has a radius of about 0.1 micrometers and a mass of 10-14 grams. Roughly how many dust particles are in a cloud containing 1000 Msun of dusty gas if 1% of the cloud's mass is in the form of dust grains? B) What surface area would be covered by these grains if you put them side by side? Assume these grains are spherical. Answer in square light-years. C) Estimate the total surface area covered by the cloud assuming it's matter density is like that of a typical molecular cloud, about 10-21 g/cm3 (Hint: first calculate the clouds volume from it's mass and density, then determine its radius using the formula for volume of a sphere) Answer in square light-years. D) Comparing all above answers, What are the chances (very roughly) that a photon passing through the cloud will hit a dust grain?arrow_forward
