Final answer:
As you go deeper into the Sun, gas pressure increases due to the stronger gravitational pull and the higher temperature of the gas. The increased number of particles and their accelerated motion contribute to this rise in pressure.
Step-by-step explanation:
When considering the question, As you go deeper in the sun, what is the effect on gas pressure?, the key factor to understand is that the Sun's immense gravity affects gas pressure significantly. As you move deeper into the Sun, the gas pressure increases. This is primarily due to two factors: the gravitational pull becoming stronger as you get closer to the center, and the increase in the temperature of the gas.
As you journey deeper into the Sun, the number of particles within a given volume of gas will rise, and so too will the combined impact of these moving particles, resulting in higher pressure. Furthermore, the inward falling layers of the Sun cause the gas atoms to move faster, increasing the kinetic energy and thereby the temperature. Since higher temperatures result in higher pressures, the temperature increase contributes to an increase in gas pressure as well.
It's also important to note that the density of the gas surrounding you would increase gradually as you fall inwards, much like falling through a cloud in skydiving on Earth; however, the temperature in the Sun would vaporize anything before reaching the high pressure core.
