Answer:

As a result of human activities, plastic impacts the envionment in negative way that leads to serious environmental danger.

Explanation:

When we don't throw away plastic materials correctly, it causes littering. Well, this can also lead to piles of that, meaning that it is spreading toxins. Littering may also lead to blockages in flowing streams, lakes, river, ground water, big bodies of water, and small bodies of water. This also can contribute to global warming because plastic are made from chemicals that come from the production of fuels like oil, gas, coal and possible more.

Answer:

$V_2=52.2L$

Explanation:

Hello there!

In this case, by bearing to to mind the given conditions, it is firstly possible to determine the initial volume of the closed system via the ideal gas equation:

$PV=nRT\\\\V=\frac{2.00mol*0.08206\frac{atm*L}{mol*K}*298.15K}{1.00 atm} \\\\V=48.9L$

Which is V1 in the Charles' law:

$\frac{T_2}{V_2} =\frac{T_1}{V_1}$

And of course, T1 is 298.15 (25+273.15). Therefore, by solving for V2 as the final volume, we obtain:

$V_2=\frac{V_1T_2}{T_1}\\\\V_2=\frac{48.9L*(45+273.15)K}{(25+273.15)K} \\\\V_2=52.2L$

Best regards!
