Answer:
Probably it was ment to illustrate how significant and indivisible, being very small, atoms are and how each of them under normal conditions of presure and temperature find their own place eventually
The model of the atom has dramatically changed over many many years.We learned atoms make up different substances and are the smallest particles of matter, which have subatomic particles that are very small portions of matter. At first scientist only thought there were electrons which are negatively charged.
i think it c i dont know if im right tho.
Answer:
The new pressure is 1.05 atm
Explanation:
Step 1: Data given
Number of moles oxygen gas = 6.2 moles
Volume of the cylinder = 4.3 L
Pressure of the gas = 3.8 atm
The volume changed to 15.5 L
Step 2: Calculate the new pressure
P1*V1 = P2*V2
⇒with P1 = the initial pressure of the gas = 3.8 atm
⇒with V1 = the initial volume = 4.3 L
⇒with V2 = the increased volume = 15.5 L
⇒with P2 = the new pressure = TO BE DETERMINED
3.8 atm * 4.3 L = 15.5 L * P2
P2 = (3.8 atm *4.3 L) / 15.5 L
P2 = 1.05 atm
The new pressure is 1.05 atm
