netineya [11]2 years ago
5 0

Answer:

The most recent Global Burden of

Disease (GBD) study estimates that air pollution – indoor and outdoor combined – was the cause of 5.5 million premature deaths

globally in 2013. Air pollution also has further consequences on human health, leading in particular to an increasing number of

respiratory and cardiovascular diseases. Moreover, it affects crop yields and the environment, with impacts on biodiversity and

ecosystems, amongst others. These impacts have significant economic consequences, which will affect economic growth as well as welfare

Andrej [43]

The final temperature : 345 K

<h3> Further explanation </h3>

Given

475 cm³ initial volume

600 cm³ final volume

Required

The final temperature

Solution

At standard temperature and pressure , T = 273 K and 1 atm

Charles's Law  :

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

V₁/T₁=V₂/T₂

Input the value :

T₂=(V₂T₁)/V₁

T₂=(600 x 273)/475

T₂=345 K

bagirrra123 [75]
Energy is ability to work or function. Power is the amount of energy transferred to an object.
When energy is transferred to an object or has energy it moves and power is the energy put in a object, meaning they work together to move the object

A chemical reaction produced 10.1 cm3 of nitrogen gas at 23 °C and 746 mmHg. What is the volume of this gas if the temperature a
adell [148]

Answer:

volume of gas = 9.1436cm³

Explanation:

We will only temperature from °C to K since the conversion is done by the addition of 273 to the Celsius value.

Its not necessary to convert pressure and volume as their conversions are done by multiplication and upon division using the combined gas equation, the factors used in their conversions will cancel out.

V1 =10.1cm³ , P1 =746mmHg,     T1=23°C =23+273=296k

V2 =? ,   P2 =760mmmHg ,     T2=0°C = 0+273 =273K

Using the combined gas equation to calculate for V2;

\frac{V1P1}{T1}=\frac{V2P2}{T2} \\ re-arranging, \\V2 =\frac{V1P1T2}{P2T1}

V2 =\frac{10.1*746*273}{760*296}

V2=9.1436cm³
