A 2.5 L container is filled with propane. The ambient temperature is 25°C and the pressure in the container is about 3 atmospheres. If the temperature in the car
reaches 55°C (about 130°F), what will be the pressure in the container?
(please your work)

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
