What happens as a protostar contracts?
A) Its density rises.
B) Its temperature rises.
C) Its radius decreases.
D) Its pressure rises.
E) All of the above are true.

Question

Quizplus · Accepted Answer

As a protostar contracts, its density rises due to the decreasing volume. This leads to an increase in its pressure and temperature since there are more collisions between particles in a smaller space. Additionally, the decrease in volume causes the radius of the protostar to decrease. So, all of the above options are true.
