Question

what is the temperature of a new star? 100 k 0 k 20 k rewatch

Explanation:

A new star (protostar) forms from a collapsing cloud of gas and dust. The temperature of a new - forming star (protostar) is around 100 K as it starts to accumulate mass and gravitational contraction begins to heat it up. 0 K is absolute zero (theoretical minimum temperature, no object can reach it), and 20 K is too low for a new - forming star's temperature.

Answer:

100 K (the option with "100 K")
