If the mass of a box is increased and the force stay the same, determine the relationship with acceleration

the acceleration will decrease, because the box will now have more friction among the ground.

The only time mass will not affect acceleration is in a vaccum

Note the standard equation is force is proportional to mass times acceleration.

air quality

poor drinking water

and heavy polution

can lead to poor health

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
