Abicycle tire has a pressure of 7.00×105 n/m2 at a temperature of 18.0ºc and contains 2.00 l of gas. what will its pressure be if you let out an amount of air that has a volume of 100cm3 at atmospheric pressure? assume tire temperature and volume remain constant.

Explanation:

from the ideal gas law we have

PV = mRT

HERE  R is gas constant for dry air  =  287  J K^{-1} kg^{-1}

We know by ideal gas law

for m_2

WE KNOW

PV = mRT

V, R and T are constant therefore we have

P is directly proportional to mass

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
