The particles of an ice cube at 0°c (represented by the blue circles) come in contact with the particles of juan’s hand at 37°c (represented by the orange circles). which diagram correctly represents the temperature of the two substances and the direction of heat flow? image for option 1 image for option 2 image for option 3 image for option 4

I believe it to be option two. Correct me if im wrong i did this test last semester

Answer :  The correct option is, (A) 446 torr

Solution :

According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.

where,

= total partial pressure = 0.610 atm = 463.6 torr

conversion used : (1 atm = 760 torr)

= partial pressure of hydrogen gas = ?

= partial pressure of water vapor = 18 torr

Now put all the given values is expression, we get the partial pressure of the hydrogen gas.

Therefore, the partial pressure of gas is, 446 torr
