Powdered urine can be purchased online in packets, and then mixed with water to form urine. ... so they would report your test as negative andyou'd get hired anyway.</span><span>

Determine the change in volume that takes place when a 3.25-L sample of N2(g) is heated from 250.0 K to 406.8 K. Enter your answ
alexgriva [62]

<u>Answer:</u> The change in volume is 2.05 L

<u>Explanation:</u>

To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

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

where,

V_1\text{ and }T_1 are the initial volume and temperature of the gas.

V_2\text{ and }T_2 are the final volume and temperature of the gas.

We are given:

V_1=3.25L\\T_1=250.0K\\V_2=?\\T_2=406.8K

Putting values in above equation, we get:

\frac{3.25L}{250.0K}=\frac{V_2}{406.8K}\\\\V_2=5.30L

Change in volume = V_2-V_1=(5.30-3.25)L=2.05L

Hence, the change in volume is 2.05 L
