What is the difference between incandescent bulbs and fluorescent bulbs Why change?
Fluorescent bulbs use less energy to produce a similar amount of light as incandescent bulbs. So they save money on power when used. But they cost more to make, and how the power consumed to make them compares I do not know. And they contain a significant amount of Mercury, making them difficult to dispose of properly. There is much debate over which is better.

Why does the colors of an object look different under a fluorescent lamp from the way it looks under an incandescent lamp?
differences in the color of light will change the color's appearance as it is seen under fluorescent and incandescent. An incandescent lamp, like the sun, produces a spectrum of light in every color in a wide band, broad enough to cover the entire visible spectrum -- and extending past it to many colors that humans can't see. A fluorescent lamp produces a spectrum of light in a few narrower bands of color. That is why a fluorescent lamp is more energy efficient than a incandescent -- the fluorescent lamp doesn't waste energy producing photons that humans can't see. Some materials (such as white paper) reflect all visible colors equally. They look white in almost any kind of light. Other materials absorb some colors more strongly than other colors. They look colored in "white" incandescent light. If we have a material that reflects most colors equally, except for a narrow band of colors, and that band is in the "dark" part of of the fluorescent spectrum -- it will look the same color as white paper. If we have another material that reflects most colors equally, except for a narrow band of colors that is in one of the bands of colors produced by a flourescent lamp -- that material will look even more deeply colored in fluorescent light than in incandescent light.
Whats the difference between activation energy and the change of energy in a PE diagram?
Activation energy is the minimum energy required for a reaction to occur, while the change in energy in a potential energy diagram represents the difference in energy between the reactants and the products of a reaction. Activation energy is specific to the transition state of a reaction, whereas the change in energy is a measure of the overall energy difference between reactants and products.
What is the change between 0.05 and 0.07?
The absolute difference is 0.02. In relative terms, we could say that 0.07 is 40 percent larger than 0.05. This calculated by dividing the difference of the two numbers by the lesser of the two: (0.07 - 0.05) / 0.05 = 0.02/0.05 = 0.4 = 40 percent.To calculate the change, just find the difference between the numbers given.0.07 – 0.05 = 0.02.If you are supposed to find the percentage of change then,Percentage of change = (Change * 100)/initial value.= 0.02*100/0.05= 2/0.05= 200/5= 40%The change between 0.05 to 0.07 is 40%Source: www.icoachmath.com
Is difference between two temperatures in kelvin is equal to degrees celsius?
Kelvin and Celsius both use the same "size" degree, but they have different zero points; 0 K = -273.15 °C. A change of 10 K is identical to a change of 10 °C; a change of -43 K is identical to a change of -43 °C.
Why do stores offices and schools use fluorescent lights instead of incandescent?
Incandescent lights are expensive to run (they give off a lot of heat was well as light), incandescent lights are much more efficient. However modern LED light bulbs are better (more efficient) than both incandescent and fluorescent lights so in the future you will see a change to the use of these.
Change the Light Bulbs!?
Still using incandescent light bulbs? If so, you're wasting electricity and your electric bill will no doubt show it. Fluorescent lighting is far from new, but the way the bulbs are shaped, is. There was a time when you couldn't buy a fluorescent light bulb to fit many existing lamps and fixtures. Someone must have heard us complain, because now you can find fluorescent bulbs in almost any shape and size. A simple and effective way to watch your electric bill go down measurably is to simply change light bulbs from incandescent to fluorescent.

What is the price difference between a normal light bulb and an energy effiecient one of the same power in Queensland?
Incandescent light bulb $2 Compact fluorescent light $4 The CFL uses about 25% of the power and last about 10 times longer before replacement is needed. The Queensland Government Climate Smart Living program will change your light bulbs for you, get a real time power meter for your house and get and energy report for your house.

Difference between change in supply and change in quantity supply?
no
What is the difference between a physical and chemical change?
A physical change is reversible, a chemical change is not.
How can you make one light bulb change different colors automatically with wiring?
A normal incandescent or fluorescent lamps can not change colors. Even an LED can not change color. But an LED can be designed to have a certain color. Color changing LED is actually a combination of of three LEDs encapsulated in one casing. By turning the LED on or off a combination of colors can be achieved.
