Problem 49

A hot rock ejected from a volcano's lava fountain cools from 1100 C to 40.0 C , and its entropy decreases by 950 J/K. How much heat transfer occurs from the rock?

Step-by-Step Solution:
Step 1 of 3

Goals • To calculate the electric potential energy of a group of charges • To know the significance of electric potential • To calculate the electric potential due to a collection of charges • To use equipotential surfaces to understand electric potential • To calculate the electric field using the electric potential Electric potential energy in a uniform field • The behavior of a point charge in a uniform electric field is analogous to the motion of a baseball in a uniform gravitational field. A charge moving in a uniform field • If the positive charge moves in the direction of the field, the potential energy decreases, but if the charge moves opposite the field, the potential energy increases. • If the negative charge moves in the direction of the field, the potential energy increases, but if the charge moves opposite the field, the potential energy decreases.
