Some picnickers stop at a convenience store to buy food, including bags of potato chips. They then drive up into the mountains to their picnic site. When they unload the food, they notice that the bags of chips are puffed up like balloons. Why did this happen?

Due to reduce in atmospheric pressure at height

Explanation:

According to simple physics, the greater the altitude the lesser will the be atmospheric pressure. When picnickers, went up on a mountain, at height the atmospheric pressure is reduced, the air pressure inside the bag being more than outside,(it became more because initially the bags were packed inside a factory that had the same pressure as that of normal surroundings) it caused the chips bag to puff up like balloon

Because of a change in pressure level

Explanation:

As we climb to higher altitudes (or heights), the air pressure around us drops.

When the potato chip was produced and sealed in bags, it was done at a lower altitude with a certain pressure level. By climbing to new altitudes (with a lower level of pressure), the air pressure within the bag of potatoes chips will try to normalize itself with the the pressure at the new altitude.

This is why the bag puffs up.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )

i truly dont know the answer wait i do its 1,3,4
