The gas inside the can and the can’s volume are both constant.
The gas pressure increases with increasing temperature.
The can will burst if the pressure becomes great enough.
The gas law that applies is Gay-Lussac’s law.

when fully inflated a hot air balloon has a volume of 1.6 *10^5 L ( liter) an average temperature of 373k and 0 967 atm . 1) Ass
Sidana [21]
1.  First, you have to find the number of moles 1.6z10^5L of gas is at 373K and 0.967atm using PV=nRT solving for n. (n=PV/RT).  Everything is in the correct units and we know R is going to be 0.08206atmL/molK since it is a constant.  
n=(0.967atmx160000L)/(0.08206atmL/molKx373K)
n=5054.8mol gas
Then you have to find the the number grams which can be found using the molar mass given as 29g/mol.  multiply 29g/mol by the number of moles of gas we found in the previous step.
5054.8molx29g/mol=146589.9g of gas
Lastly, to find the density of the gas you need to divide the mass of the gas by its volume.
146589.9g/160000L=0.916g/L

2. The dinsity of the gas at STP should be higher than the density of gas with the given conditions.  This is due to the fact that the given conditions involves a higher temperature than that of at STP which will cause the gas to expand therefore increasing the volume with out increasing the mass.  The reason why the pressure is not building up even though the pressure is higher is that the balloon is not sealed meaning the gas can maintain about atmospheric pressure while expanding since the excess are just leaves the balloon.
the answer to part 2 can be proven by the fallowing:
To find the density of the gas at STP you first multiply the molar volume of gas at STP by the number of moles of gas from part 1 to get the volume of the gas at STP.
5054.8molx22.4L/mol=113228L
Then you divide the mass form part by the new volume to get the new density.
<span>146589.9g/113228L=1.30g/L</span>

I hope this helps.  Let me know in the comments if any of it is unclear.

___________ polymers can be produced in large quantities at low cost. please. thank you.
MA_775_DIABLO [31]

Answer:

Plastic polymers

Explanation:

Plastic polymers are usually made up of synthetic and semi-synthetic polymers such as polyethylene, polystyrene etc.

Plastic polymers have a unique property called malleability. Malleability is the ability of a substance to be moulded into different sizes and shapes.

When hear is applied plastics gets soft and can be molded into different forms and then it becomes hardened after exposure to air(dried).

The plastic polymers are usually very cheap to produce in large quantities which is why it is very common in industries.
