Describe how electrons travel in a conductor.
What will be an ideal response?
If electrons are added to one end of a conductor and provision is made to take electrons from the other end, an electric current flows through the conductor. As free electrons move slowly through the conductor, they collide with atoms, knocking other electrons free. These new free electrons travel toward the positive end of the conductor and collide with other atoms. The electrons drift from the negative to the positive end of the conductor because like charges repel. In addition, the positive end of the conductor, which represents a deficiency in electrons, attracts the free electrons because unlike charges attract.

0.5 kg of water at 120°C occupies a volume of 0.12 m3. The specific volume of saturated liquid water, vf, at 120oC is 0.0010603 m3/kg, and the specific volume of saturated water vapor, vg, at 120°C is 0.8919 m3/kg. Find the quality of the saturated mixture.
Given: m = 0.5 kg; V = 0.12 m3; vf = 0.0010603 m3/kg; vg = 0.8919 m3/kg What will be an ideal response?
