the first molecular clouds had almost no dust, but were fairly dense and could cool by slow radiation to about 100 k. what does the fact they were relatively warm tell us about the masses of the first generation of stars?

The fact they were relatively warm tells us that  They were massive stars of about 200-300 solar masses. Because only relatively large clouds could collapse, the first generation of stars had to be very massive.The first generation of stars, ones made as it were from ingredients given specifically by the enormous big bang. Made of basically as it were hydrogen and helium, these so-called population III stars are anticipated to be gigantic in measure and to live quickly and die young. The clouds of gas within the early universe would have remained generally warm from the big bang and so would resist condensing down to create stars. Blending in a little sum of heavier components makes a difference to the gas clouds to be cool, since those components are less demanding to ionize and so shed warm as radiation. But those heavy components hadn't however shaped within the early universe, so stars developed to gigantic sizes—hundreds or indeed a thousand times as huge as our sun—before their centers were thick sufficient to start combination. Once they did get begun, they burned fast and hot, transmitting lots of ultraviolet light and burning out for several million of years. Fusion within the centers of stars merges light particles into heavier ones, all the carbon, oxygen, press, and everything else required to create  dust clouds, planets, and lifeTo know more about big bang  refer to the  link  https://brainly.com/question/17209127?referrer=searchResults.#SPJ4
