Amonatomic, ideal gas is in a sealed container (the number of gas molecules is always constant: n = 2 moles); the initial pressure is pi = 1.01 × 105 pa and the initial volume is vi = 0.0224 m3. first, the volume of the gas is decreased at a constant pressure (at pi = 1.01 × 105 pa) to a final volume of vf = 0.0155 m3. second, the pressure of the gas is increased at a constant volume (at vf = 0.0155 m3) to a final pressure of pf = 1.35 × 105 pa. how much heat was added to (give as a positive number) or removed from (give as a negative number) the system? (the gas constant r = 8.31 j/mole-k.) q =

Using proper grammar, spelling, and punctuation, write at least one 5 sentence paragraph describing 3 ways we use the elements of the electromagnetic spectrum (ems) in our everyday lives.

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?
