Answer: The answer is C light pretty obvious.
Explanation:
Answer:
Explanation:
Carbon (coke) burns in air to form carbon dioxide gas.
(i) C(s) + O2 ↑= CO2 ↑
Correct answer: <span>An isomer with a branched structure will require:
less energy to melt than the straight chain structure.
Reason:
</span>
The branched chain compounds have lower melting and boiling points as compared to straight chain isomers.This is due to the fact that branching makes the molecule more compact. This results in decreases in surface area of isomer. But, the intermolecular attractive forces depends on the surface area of compound. Thus, branched isomers have lower intermolecular force of interaction, as compared to straight chain isomers. Consequently, the melting/boiling points of the branched chain isomers are lower as compared to straight chain isomers.
Answer:
Heat is the sum of all the kinetic energies of all the molecules of an object, while temperature is the average kinetic energy of the molecules of an object
