Question

the energy the sun gives off is caused by nuclear reactions in its core. the extreme pressure from the weight of the gases that make up the sun raises the temperature of the core enough for the nuclear reactions to take place. which law best describes this behavior of gases in the sun? charless law boyles law gay - lussacs law

Explanation:

1. Recall the gas laws:

• Charles's law: Relates volume and temperature at constant pressure ($V_1/T_1 = V_2/T_2$).
• Boyle's law: Relates pressure and volume at constant temperature ($P_1V_1 = P_2V_2$).
• Gay - Lussac's law: Relates pressure and temperature at constant volume ($P_1/T_1 = P_2/T_2$).

1. In the Sun's core, the volume of the gas (the core) can be considered constant (the Sun's core volume doesn't change significantly in the context of the pressure - temperature relationship for the nuclear reactions). The extreme pressure from the weight of the gases (increase in pressure) raises the temperature of the core (increase in temperature). This relationship between pressure and temperature at constant volume is described by Gay - Lussac's law.

Answer:

Gay - Lussac's law
