Answer:
a) Halophile
Explanation:
Halophiles are extremophiles characterized by their ability to thrive in very hot and salty conditions, such as salt flats, salt mines, or hypersaline environments. They have adapted to high levels of salt and can withstand extreme salinity.

Answer: ability to dissolve ionic substances
Explanation: Water is made up of hydrogen and oxygen molecules. The less electronegative hydrogen atoms occupy partial positive charge and oxygen being more electronegative occupy partial negative charge.
Due to this polarity, it is able to interact with ionic substances and thus dissolve them easily which is explained by the statement Like dissolves like. The ionic compounds are soluble in polar solvents and non ionic compounds are soluble in non polar solvents.
The ability to dissolve ionic substances is primarily due to the uneven distribution of charge between the hydrogen and oxygen atoms in water.
Water is a polar molecule, meaning it has a positive charge on one side (hydrogen) and a negative charge on the other side (oxygen). This polarity is a result of the unequal sharing of electrons between the hydrogen and oxygen atoms in the water molecule. The oxygen atom has a higher electronegativity than the hydrogen atoms, pulling the shared electrons closer to itself, resulting in a partial negative charge around the oxygen atom and a partial positive charge around the hydrogen atoms.
Because of its polarity, water molecules are attracted to ions in ionic substances. When an ionic compound, such as sodium chloride (NaCl), is added to water, the polar water molecules surround and separate the positive and negative ions, breaking the ionic bonds and causing the substance to dissolve. This ability of water to dissolve ionic substances is essential for various biological processes and makes it an excellent solvent for many substances.
In contrast, the other properties listed (color, taste, ability to produce buoyant forces) are not primarily related to the uneven charge distribution in water molecules but are influenced by other factors such as impurities, dissolved substances, and the reflection of light.

(3) CH3CHO and CH3COCH3
(4) CH3CH2OH and CH3OCH3
Answers
Answer is (4) - CH₃CH₂OH and CH₃OCH₃.
Both CH₃CH₂OH and CH₃OCH₃ have same molecular formula as C₂H₆O. But CH₃CH₂OH is an alcohol and CH₃OCH₃ is an ether.
Although two compounds have a same molecular formula, the atomic arrangement of those compounds differs from each other.
Hence, CH₃CH₂OH and CH₃OCH₃ are isomers of the formula C₂H₆O.
Due to the different arrangement of atoms, both compounds have different chemical and physical properties.

The answer is sublimation.
Sublimation is the chemical process whereby a solid turns into a gas without first becoming a liquid.
The word sublimation comes from the Latin word sublimare which means "raised to a higher status."
Examples of sublimation include surface layer of snow and ice turning into steam or fog without melting and dry ice which is the solid form of carbon dioxide which also undergoes sublimation.
The low temperature and sublimation makes dry ice an effective coolant or cooling agent . One of its main advantages is that it has a lower temperature than water ice and also does not leave any residue.
