To solve this problem, it is necessary to apply the ideal Gas equations, as well as the calculation equations of the weight difference, which under the comparison of two values.
By definition we know that the ideal gas equation is given by the equation,
PV = nRT
Where,
P = Pressure
V = Volume
R = Gas ideal constant
T = Temperature
n = number of moles
Our values are given by
PART A) Using this previous equation we can find the number of moles per Volume, that is
Replacing with our values
PART B ) We can calculate the number of moles of 1m^3 through Avogadro number, then
Therefore in there are 1.1524Kg of Gas.
PART C ) Density can be defined as the proportion of mass in a specific quantity of Volume, then
The difference of percentage then is
YES, because as the percentage is less than 10%, the calculated value agrees with the stated value.
The pressure at the bottom of a column of fluid in a container
depends only on the depth of the fluid, not on the shape of the
container. The pressure is simply the result of the weight of the
fluid resting on the bottom.
Answer:
D).happens when soil is weakened by water and seismic waves
Explanation:
Liquefaction is a phenomenon in which the strength of the soil weakens due to the earthquake or any other load. The solid behaves like a liquid. Liquefaction of soil below structures cause lot of damage during Earthquakes.The soil looses stiffness due to seismic waves and water.
Thus, the correct option is D.
