The image above shows a gas held in a chamber with a fixed volume. The gas begins with a temperature 333 K and a pressure of 4.0
lana66690 [7]

Answer:

636.86 K

Explanation:

From the question given above, the following data were obtained:

Initial temperature (T1) = 333 K

Initial pressure (P1) = 4 atm

Final pressure (P2) = 7.65 atm

Final temperature (T2) =?

NOTE: The volume is constant.

Since the volume is constant, we can obtain the new temperature the gas by using the following formula as illustrated below:

P1 /T1 = P2 /T2

4/333 = 7.65/T2

Cross multiply

4 × T2 = 333 × 7.65

4 × T2 = 2547.45

Divide both side by 4

T2 = 2547.45 / 4

T2 = 636.86 K

Therefore, the new temperature of the gas is 636.86 K

Hi, There!...

<h2>Answer</h2>

My Answer would be Option B.

Explanation:

nuclear energy protects air quality by producing massive amounts of carbon-free  electricity.

Thermal energy from nuclear reactors may also be used to decarbonize other energy-intensive sectors such as transportation – the largest contributor to carbon pollution.
