The atmospheric pressure will be:
The pressure of the atmosphere resulting from the mercury column is 0.959 atm
What is atmospheric pressure?
The force that an object experiences from the weight of the air above it per unit area are known as atmospheric pressure.
Given: Height of mercury column = 729 mm Hg
To find: The pressure of the atmosphere
Calculation:
The atmospheric column resulting from the mercury column is calculated as follows:
1 atm =760 mm Hg
So, we can convert the 729 mm Hg to atm, and we get
Atmospheric pressure = 729 x 1 atm / 760 = 0.959 atm

easy there are three levels so you look at the periodic table and go to the third row now the last level on this atom is 1 electron so your answer is <u>Na</u>
<span>Decreasing the temperature will decrease the pressure of a gas inside a closed cubical container.
In a closed container, the Volume (V) is fixed and the no of mole of the gas(n) are also fixed. So, we write the gas equation : PV = nRT
Here, V,R and n are constants.
So, Pressure is directly proportional to the temperature. Thus, on increasing the temperature, pressure will increase and on decreasing the temperature, the pressure will decrease.</span>
Conduction causes it to become hot, the molecules in the hot soup want to be on the cold spoon so they move to it, making the spoon hot.
