Activity Constructing a model of an electric drauit.
What you need: 2 batteries 1.5v, electrical tape, socket, 1 flashlight bulb
15 v, two 25 cm. insulated wire with end scrapped, 1/8
size illustration board, scissors
1. On the illustration board, arrange a circuit to light a bulb
2. Screw the bulb into a socket. Connect a copper wire to each of the sockettering
3. Connect a piece of copper wire to the switch. Connect the lone end of the wire to the nerve end of the
battery
4. Connect one end of the copper wire by winding it which is attached to the socket) to the positive end of the
battery. Connect the other end of the socket to the switch. Did the bulb light
5. Fasten the wires, batteries, and bulb into the illustration using the electrical to secure the circuit and connections
6. Close the open parts of the switch. What happened to the bulb? Why?
7. Switch it off. What happened to the bulb?​

1. they vary with a higher number because boiling is way hotter than melting

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
