A sample of 500 mL Ne gas is at 0.868 atm and 55 C. What is the new volume if the pressure is increased to 1.35 atm and the temp

WITCHER [35]

<h3>Answer:</h3>

292.10 mL

<h3>Explanation:</h3>

From the question we are given;

Initial volume, V1 of Ne gas is 500 mL
Initial pressure, P1 of Ne gas is 0.868 atm
Initial temperature, T1 of Ne gas is 55°C
but, K = °C + 273.15, thus, T1 = 328.15 K
Final pressure of the gas, P2 = 1.35 atm
Final temperature of the gas, T2 = 25°C

= 298.15 K

We are required to calculate the new volume, V2 of the gas;

Using the combined gas equation;

$\frac{P1V1}{T1}=\frac{P2V2}{T2}$

Rearranging the formula we can calculate the new volume, V2;

$V2=\frac{P1V1T2}{P2T1}$

$V2=\frac{(0.868atm)(500mL)(298.15K|)}{(1.35atm)(328.15K)}$

$V2=292.10mL$

Therefore, the new volume is 292.10 mL

Answer:

The breakup sort of resembles the Pangea since the Pangea was a large supercontinent before it split into smaller continents. The plates are also moving a slow rate similar to how Pangea slowly broke up.
