Answer 1

Definition of mm Hg : mm Hg is a unit of pressure equal to the pressure exerted by a column of mercury 1 millimeter high at 0°C and under the acceleration of gravity and nearly equivalent to 1 torr (about 133.3 pascals) 1 mm Hg to torr = 1 torr For all problem Given pressure is 652.5 mm Hg Question A This question the given value needs to convert mm Hg to torr conversion, Already we knew 1 mm Hg is equal to 1 torr , So, 652.5 mm Hg = 652.5 torr. Question B This question the given value needs to convert mm Hg to atm conversion. 1 mmHg to atm = 0.00132 atm So, 652.5 mm Hg = 0.00132 * 652.5 = 0.8585526858077587 atm Question C This question the given value needs to convert mm Hg to Hg conversion. 1 mm Hg to in Hg = 0.03937 in Hg So, 652.5 mm Hg = 0.03937 *652.5 = 25.688973649597425 Hg Question D This question the given value needs to convert mm Hg to psi conversion. 1 mm Hg to psi = 0.01934 psi , so 652.5 mm Hg = 0.01934 *652.5 = 12.617247316397085 psi
