Consider five spherical clouds of gas, each of which has a mass about 50 times that of the Sun, with the following properties. For each cloud, select whether it will undergo gravitational collapse, will not undergo gravitational collapse, or whether it lies close to the boundary. Cloud 1: R= 107 Ro, T=35 K neutral hydrogen atoms Cloud 2: R= 10$ RO, T=25 K neutral hydrogen atoms Cloud 3: R= 10° Ro , T=10 K neutral hydrogen atoms Cloud 4: Cloud 5: R= 108 Ro , T= 30 K neutral helium atoms R= 106 Ro , T=20 K neutral helium atoms will collapse will not collapse close to the boundary
A quantity of helium gas is originally held under a pressure of 145 kPa at 18°C.
