Acylinder containing 44.0 l of helium gas at a pressure of 170 atm is to be used to fill toy balloons to a pressure of 1.1 atm. each inflated balloon has a volume of 2.0 l. what is the maximum number of balloons that can be inflated? (remember that 44.0 l of helium at 1.1 atm pressure will remain in the 'exhausted' cylinder) round your answer to two significant digits.

- 3400 balloons

Solution:- Originally the helium gas is at 170 atm pressure and there are 44.0 L of it. The pressure of the balloon filled by this has is 1.1 atm and the volume is 2.0 L. Let's first calculate the pressure of helium gas at 1.1 atm of pressure using Boyle's law, "At constant temperature, the volume of the gas is inversely proportional to the pressure."

The equation used for this is:

= 170 atm

= 1.1 atm

= 44.0 L

= ?

Let's plug in the values and solve this for .

= 6800 L

Now, 44.0 L of the gas is remaining in the exhausted cylinder at 1.1 atm of pressure.

So, the volume of the gas used to fill the balloons = 6800 L - 44.0 L= 6756 L

2.0 L is the volume of one balloon filled by the helium gas. 6756 L would be the volume of how many balloons?

We could easily solve this on dividing the above calculated total volume used to fill the balloons by the volume of one balloon.

= 3378 balloons

The answer is asked to be reported with two sig figs, so it could be written as 3400 balloons.

Hence, 3400 balloons could be filled by the helium gas.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.

explanation:

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong
