Answer:
Explanation:
Potential energy is the energy stored within an object, due to the object's position, arrangement or state
PV = nRT ....... ideal gas law
divide state 1 by state 2
WARNING: CONVERT ATM TO KPA
(0.923atm)(150ml) / (0.987atm)(V2) = 1
1 because constant temperature
solve for V2. all the best
Answer:
The number of moles of the air is 4.464 x 10⁻⁴ mole
The number of molecules is 2.688 x 10²⁰ molecules
Explanation:
Given;
pressure of the air, P = 1 atm
volume of the air, V = 1 m³
temperature of the air, T = 0° C = 273 K
The number of moles of the air is calculated as;
PV = nRT
where;
n is the number of moles
R is ideal gas constant = 8.2057m³atm/mol.k
The number of molecules is calculated as follows;
1 mole ---------------------> 6.022 x 10²³ molecules
4.464 x 10⁻⁴ mole ----------> ?
= (4.464 x 10⁻⁴) (6.022 x 10²³ molecules)
= 2.688 x 10²⁰ molecules of air.
Torque = (force perpendicular to the radius) x (length of the radius)
Torque = (25 N) x (5 m)
<em>Torque = 125 N-m</em>
