In which way does electricity flow in a DC circuit? * From the negative terminal of the battery to the positive one
From the positive terminal of the battery to the negative one
The electricity flows first from the negative terminal to the positive one, then the
polarity switches
The electricity flows first from the positive terminal to the negative one, then the
polarity switches

From the negative terminal of the battery to the positive one

Explanation:

   DC is just  dirrect current that has e- flowing from the negative terminal to the positive.

you need to give more information

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
