Kiki makes a table to compare the particles in a magnesium atom to those in a magnesium ion. she knows that a magnesium ion has an electric field that points away from the ion. what values should she use to complete her table?
(the table looks something like this:
magnesium atom magnesium ion
protons (magnesium atom)12 (and magnesium ion) x
neutrons (ma)12 (mi)y
electrons (ma) 12 (mi) z
a. x: 14 y: 12 z: 12
b. x: 12 y: 12 z: 10
c. x: 12 y: 10 z: 12 x: 12
d. y: 12 z: 14

Na food processing facility, a spherical container of inner radius r1 5 40 cm, outer radius r2 5 41 cm, and ther- mal conductivity k 5 1.5 w/m · k is used to store hot water and to keep it at 100°c at all times. to accomplish this, the outer surface of the container is wrapped with a 800-w electric strip heater and then insulated. the temperature of the inner surface of the container is observed to be nearly 120°c at all times. as- suming 10 percent of the heat generated in the heater is lost through the insulation, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the container, (b) obtain a relation for the variation of temperature in the container material by solving the differential equation, and (c) evaluate the outer surface tempera- ture of the container. also determine how much water at 100°c this tank can supply steadily if the cold water enters at 20°c.

What are the theoretical properties of a gas at a temperature of 0 kelvin?

Convection occurs when thermal energy is transferred by the movement of
