Amass of a gas has a volume of 4m’3 a temperature of 290 k an obsolete pressure of 475 kpa. when the gas is allowed to expand to 6.5 m’3, it’s new temperature is 277 k. what is the absolute pressure of the gas after expansion? thnk you

By idea gas equation we can say

here P = pressure

V = volume

n = number of moles

R = Avagadro gas constant

T = temperature

So from above expression we can see that for constant number of moles we can say

So finally the pressure will be 279.1 kPa

number of electrons for neutral cl

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
