Gas pressures can be expressed in units of mm Hg, atm, Torr, and kPa. Convert these pressure values: 1. 720 mm Hg to atm 2. 1.25 atm to mm Hg 3. 542 mm Hg to Torr 4. 740 mm Hg to kPa

00:01 We have been questioned that is asked here we convert these pressure into the unit which we are given so here we know the force that exert in a unit area is known as pressure in the form of equation it is denoted as we know p is equal to f divided by a so here the si unit of pressure right si unit of resor which is here we write newton then meter to the power minus 2 so here this is can be said the as pascal so therefore their various unit can be used to express the pressure some are them which are what atm so you write the units are atm then tar then you write m m hg then p hg then psaid then kpa etc so here all this unit here we convert to one another using the conversional factor so here we have given in the a bit so here in the a bit we have given the value of pressure here you write pressure here you write at pressure value which is given in here 720 m m s g you write 720 msg the required value of the unit which is 80m so you rewrite which is in the form of the atm the conversational factor that is used for which is the m m hg and here you write at tm given as here we write 1 .0080m which is divided by 760 mhm or here we take what you write 760 mhm hg or here you write 760 mhm hg which is divided by here you write 1 .0080m so here we use the first conversational factor to obtain the value in the atm so which is here we write pressure which is equal to right 720 m mhg then which is multiplied by 1 .0 here you write 1 .00 80m then divided by 760 mhm here here m m m msg what cancel out then the value became you write it 0 .947 here the unity is 80m so which is approximately here is 0 .95 here we write at 8m thus here the 720 m s g in the term of 80m which became here 0 .9580m so we come from the b -bit which is given so here you write in the b -bit we have given pressure value here you write pressure here you write what pressure value here right here you write 1 .2580m so here the required pressure value is the unit of your m m hg because here we have given in the form of atm so the conversational factor which is used for here m m hg and atm which is here we write what one point here write 1 .0080m which is divided by what as 760 m m hg or here we write 760 m m hg or here we write 760 m m m hg or here we write 760 m m m then which divided by here you write 1...
