A0.907 mole sample of ideal gas at 12c occupies a volume of 4.25l. what is the pressure of gas?

Pressure of the ideal gas=505.7kPa

Given:

No of moles=0.907mole

Temperature of the gas=

Volume of the gas=4.25L

To find:

Pressure of the gas

Step by Step Explanation:

Solution:

According to the ideal gas equation

and from this pressure is derived as

Where P=Pressure of the gas

V=Volume of the gas=4.25L

n=No of the moles=0.907mole

R=Gas constant=8.314

T=Temperature of the gas= =273+12=285K

Substitute these known values in the above equation we get

P=505.7kPa

Result:

Thus the pressure of the ideal gas is 505.7kPa

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
