Students are investigating the relationship between pressure and temperature in August they have blown up a balloon with carbon dioxide from an editing and connected the balloon to a pressure gauge The balloon is then sobmerged in ice Or water baths at various temperatures In order to observe the pressure level after several minutes what is a flaw in the student investigation and how can the students improve their investigation to correctly determine the relationship

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c. m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
