Which compound has the highest boiling point? Explain your reasoning. CH4 or CH3CH3
2 answers:
Answer:
The correct answer t is ; has a lower mass compared to
which leads to a higher boiling point.
Explanation:
Boiling point of alkanes increases with increase number of carbon atoms in the chain.
This is because along with increase in carbon atom molar mass of alkane also increases by which surface area of molecule increases which further results in increase in weak vander wall forces among the molecule. Due to this molecules associates strongly with each other and boils at high temperature

The period will be the same if the amplitude of the motion is increased to 2a
What is an Amplitude?
Amplitude refers to the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
Here,
mass m is attached to the spring.
mass attached = m
time period = t
We know that,
The time period for the spring is calculated with the equation:
Where k is the spring constant
Now if the amplitude is doubled, it means that the distance from the equilibrium position to the displacement is doubled.
From the equation, we can say,
Time period of the spring is independent of the amplitude.
Hence,
Increasing the amplitude does not affect the period of the mass and spring system.
