Consider the same situation as last question: a 4.3 mole sample of gas in a 0.25 l container is held at a temperature of 175 k. now assume that the gas is not behaving ideally (so you must use the van der waals equation). for this gas sample, a is 2.1 atm l2 mol-2 and b is 0.042 l mol-1. what is the pressure of the gas sample? report your answer in atmospheres to the nearest whole number.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
