Answer:

It is often necessary to start campfire with many pieces of kindling rather than large logs because it is easier to ignite smaller pieces than larger pieces. Imagine wanting to light up a pile of clothes and a small piece of a shirt. Which ignites faster? The piece of a shirt, because it is smaller and more likely to burn very quickly. Additionally, people criss-cross these tiny pieces of wood to enable more surface area and to allow more oxygen to pass through. As you know, oxygen is necessary for a flame to ignite.

Add a temperature of -33.0 Celsius a sample of a confirmed gas eggs or to pressure of 0.5 to 6 ATM if it's volume remains consta
Levart [38]

<u>Answer:</u> The final temperature of the gas is -220.6°C

<u>Explanation:</u>

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

Mathematically,

\frac{P_1}{T_1}=\frac{P_2}{T_2}

where,

P_1\text{ and }T_1 are the initial pressure and temperature of the gas.

P_2\text{ and }T_2 are the final pressure and temperature of the gas.

We are given:

P_1=6atm\\T_1=-33^oC=[273-33]K=240K\\P_2=1.31atm\\T_2=?

Putting values in above equation, we get:

\frac{6atm}{240K}=\frac{1.31atm}{T_2}\\\\T_2=\frac{1.31\times 240}{6}=52.4K

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:

T(K)=T(^oC)+273

52.4=T(^oC)+273\\\\T(^oC)=-220.6^oC

Hence, the final temperature of the gas is -220.6°C

Its chemical formula H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is the name of the liquid state of H2O at standard conditions for temperature and pressure.
