Lisa places a beaker of ice water on a hot plate and measures the temp of the ice water to be 0c. she turns on the hot plate and observes the ice began to melt. when half of the ice is melted she measures the temp again. which of the following is most likely? a) the temp is staying at 0c b) the temp has increased to 20c c) the temp has decreased to -20c d) the particles have stopped moving and she is unable to measure any temp

, answer fast i will give max points, !

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
