Question

While a star is on the main sequence, its equilibrium is the result of the outward pressure of hot gas and the inward pressure of ________.

Answer 1

Gravity

Step-by-step explanation:

While a star is on the main sequence, its equilibrium is the result of the outward pressure of hot gas and the inward pressure of GRAVITY.

Gravity is a property of mass of objects. Pressure gravity is the resultant force felt by a particular mass object.

As gravity contact the star surface, density gradient is set up.

Pressure of gravity is a gravitational compression which increases the objects density, compresses the mass of objects and reduces the object's size.

A star might leave the sequence if the star run out of fuel for nuclear fusion in its core.

Answer 2

Answer: While a star is on the main sequence, its equilibrium is the result of the outward pressure of hot gas and the inward pressure of _gravity _______.

Step-by-step explanation:

Inside a star, the inward force of gravity is balanced by the outward force of pressure. The star is stabilized (i.e., nuclear reactions are kept under control) by a pressure-temperature thermostat.
