1.4 atm
Explicación
This question is about Boyle's Law, which states that the pressure and volume of a gas have an inverse relationship when temperature is held constant. If the volume of the gas increases, the pressure decreases and vice versa. The formula for Boyle's Law is P1V1 = P2V2, where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume. In this case, the initial pressure (P1) is 5 atm, the initial volume (V1) is 7 L, and the final volume (V2) is 25 L. We need to find the final pressure (P2). Plugging the given values into the formula, we get 5 atm * 7 L = P2 * 25 L. Solving for P2, we get P2 = (5 atm * 7 L) / 25 L = 1.4 atm. Therefore, the pressure of the gas when the volume changes to 25 L is 1.4 atm.
