Answer: The first one is your answer. (If two people pull on it in opposite directions, it stretches. Then when they let it go, it returns to its original size and shape.)
<u>Answer:</u> The final temperature will be 
<u>Explanation:</u>
Calculating the heat released or absorbed for the process:
In a system, the total amount of heat released is equal to the total amount of heat absorbed.
OR
......(1)
where,
= specific heat of aluminium = 
= heat capacity of water = 
= mass of aluminium = 30. g
= mass of water = 50. g
= final temperature of the system = ?
= initial temperature of aluminium = 
= initial temperature of the water = 
Putting values in equation 1, we get:
Hence, the final temperature will be
Only C is correct.
A will produce either an methylbromide + alcohol
B will produce alcohol and alkyl bromide as well
C cyclic ether when reacted with HBr will only produce 1 product which has alcohol group (-OH group) on one end and Bromide group on the other end
