Energy cannot be created or destroyed. It can only be transferred from one form to another. Energy that is "wasted," does not di

sappear. Instead, it is transferred to its surroundings and spreads out so much that it becomes difficult to do anything useful with it. Incandescent light bulbs are very inefficient in energy transfer. Energy-saving lightbulbs, such as fluorescent bulbs transfer a greater proportion of electrical energy as light energy. In fluorescent bulbs what kind of energy is "wasted" in the energy transfer from electricity to light?
A) heat energy
B) kinetic energy
C) chemical energy
D) electrical energy

Answer:

A: heat energy

Explanation:

because as we light up the bulb it gives us light energy

but when we touch it we feel that it is hot (heat energy)

the heat energy given of is not for our use and goes to waste

Answer: Option (A) is the correct answer.

Explanation:

Heat energy is defined as the energy produced due to the movement of particles, atoms or molecules in an object.

Kinetic energy is defined as the energy acquired by the molecules of an object because of their movement due to increase in temperature. More is the increase in temperature more will be the movement of molecules.

Chemical energy is defined as the energy which is stored within the bonds of a chemical compound.

Electrical energy is defined as the energy which arises due to the flow of electrons or ions in a substance.

In fluorescent bulbs, heat energy is wasted in the energy transfer from electricity to light.

Thus, we can conclude that heat energy is wasted in the energy transfer from electricity to light.

Dehydration is a reversible process. Which of the two set-ups, distillation or
Nata [24]

Answer:

             Distillation will generate the most cyclohexene.

Explanation:

                     Let us assume following attached reaction for the synthesis of cyclohexene from cyclohexanol which attains equilibrium after certain time.

As shown in figure the cyclohexanol upon treatment with phosphoric acid undergoes dehydration reaction (removal of water) and produces cyclohexene. On the other hand cyclohexene reacts with water (hydration reaction) and produces cyclohexanol.

Now, if this reaction is allowed in a single flask it will attain equilibrium and will not generate the cyclohexene in high quantity. On the other hand if we apply <em>Le Chatelier's principle</em> ( <u><em>removal of product moves the equilibrium in right direction</em></u>) and distillate cyclohexene (boiling the cyclohexene to convert it into vapors and then collect it after condensation) will move the reaction in forward direction and will allow us to generate cyclohexene in high amounts.

Assignment<br>Explain why it is not advisable to wear<br>black silky cloth in the sun​
Crazy boy [7]

Answer:

It is not water absorbant and also the colour black, due to it's dark nature makes the person wearing the cloth feel hot. Unlike cotton, silk is not at all water absorbant as it does not absord any sweat produced in the wearers body
