Answer:
water is H2O having different structure than alcohol R-OH which means they have different properties too.
Explanation:
In water one oxygen atom is covalently bound with two hydrogen atoms while alcohol is an organic compound having Oh group attached to the carbon chain.
Other than liquid water can occur in solid form that is ice and in gaseous form that is vapors too while alcohol only present in liquid form.
heat of evaporation of alcohol is lower than water means water need more heat to evaporate than alcohol that is why we can say alcohol having more cooling effect than water.

The pineal gland regulates salt and water levels.
I believe the correct answer is option B. Molarity is the <span>number of moles of solute that is dissolved in 1 liter of solution. It is another way of expressing concentration of a mixture especially for solutions. Percent by mass is grams solute per grams of solution. Percent by volume is liter solute per liter per solution.</span>
Answer:
No reaction is observed
Explanation:
The benzene ring is aromatic. Being an aromatic ring, the benzene ring is remarkably stable to all reactions that destroy the aromatic ring.
Alkenes are oxidized to alkanols in the presence of KMnO4 but this reaction does not occur with benzene. However, substituted benzenes having hydrogen atoms attached to the substituent carbon atom can be oxidized to the corresponding carboxylic acid.
Something created for using science for use by society. Hence, option A is correct.
<h3>What is science?</h3>
Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence.
Technology is the use of science to provide human problem. It can be in the form of a machine, tool or equipment. As long as it involves applying a scientific process, it's technology.
Example of technology is a computer. It's used to store and process data in a faster way. Old technology also included Hammer, Saw, Grinding Machines etc.
Hence, option A is correct.
