Answer: B) Solid water to liquid water. 
Explanation: This would be the melting of water or a transition of solid water to liquid water as energy is added.
 
        
             
        
        
        
Answer:
 W = 2.3 10² 
Explanation:
The force of the weight is
          W = m g
          
 let's use the concept of density
          ρ= m / v
 the volume of a sphere is
          V =  π r³
 π r³
          V =  π (1.0 10⁻³)³
 π (1.0 10⁻³)³
          V = 4.1887 10⁻⁹ m³
the density of water ρ = 1000 kg / m³
           m = ρ V
           m = 1000 4.1887 10⁻⁹
           m = 4.1887 10⁻⁶ kg
therefore the out of gravity is
           W = 4.1887 10⁻⁶ 9.8
           W = 41.05 10⁻⁶ N
now let's look for the electric force
            F_e = q E
            F_e = 12 10⁻¹² 15000
            F_e = 1.8 10⁻⁷ N
          
the relationship between these two quantities is
            = 41.05 10⁻⁶ / 1.8 10⁻⁷
 = 41.05 10⁻⁶ / 1.8 10⁻⁷
            \frac{W}{F_e} = 2,281 10²
              
              W = 2.3 10² 
therefore the weight of the drop is much greater than the electric force
