When you flick on a light with a regular incandescent bulb, electricity is converted to heat in the tiny, tungsten wire inside. In a 75-watt bulb, the wire heats up to about 4600 degrees Fahrenheit! At such a high temperature, the energy radiating from the wire includes some visible light. Incandescent light bulbs aren’t the most efficient light source, though, because 90% of the electricity they use produces heat, while a measly 10% produces light.

Fluorescent bulbs are designed to produce light without so much heat. Forty percent of the electricity they use produces light, which might not sound so impressive unless you compare it with incandescents.

When you turn on a fluorescent light, electrons collide with mercury atoms inside the bulb, producing ultraviolet light. We can’t see ultraviolet light, so there’s a thin layer of phosphor powder inside the bulb to convert the ultraviolet to visible light. Fluorescent bulbs stay cooler because this process produces much less heat to begin with, and because their bigger size helps disperse heat more quickly.

What do these heated differences mean for energy efficiency? A regular incandescent light bulb uses about four times as much energy as a fluorescent bulb, to produce the same amount of light.

Particles in plasmas collide more often, but that does not necessarily give them higher temperature.

Plasma particles have high kinetic energy (they move quickly).

Plasma particles are far apart.

The plasma in a fluorescent bulb has a low density.

hram777 [196]

The atomic structure of an atom is well explained experimentally by different experiments like Rutherford's experiment etc

Based on these experiments it was determined that the atoms contains a central part known as nucleus which contains the positively charged sub atomic particles protons and neutral sub atomic particles neutron.

There is empty space around the nucleus in which negatively charged subatomic particles are found known as electrons.

So answers are

a) protons

b) neutrons

c) electrons

In the following reaction, how many liters of oxygen will react with 270 liters of ethene (C2H4) at STP?
lawyer [7]
According to the equation you have 1 mole of C2H4 and 3 moles of O2.

1 • (22.4L / 270L) = 3 • (22.4L / x)

1/270L = 3/x

x = 3(270) / 1

x = 810 L

810 Liters of oxygen will react with 270 liters of ethene (C2H4) at STP
