Explanation:
It is given that,
An electron is located on a pinpoint having a diameter of 3.52 µm,
We need to find the minimum uncertainty in the speed of the electron. It can be calculated using Heisenberg uncertainty principal as :
Since, p = m v
So,
So, the minimum uncertainty in the speed of the electron is greater than 16.57 m/s. Hence, this is the required solution.
<u>Answer:</u>
<em>The property helps to explain this difference is forces between molecules.</em>
<em>Option c</em>
<u>Explanation:</u>
The exact heat of water is
The exact heat of methane is
This is due to the polarity and the hydrogen bonding.
It takes more energy to break these bonds than methane, therefore, we would think water to have a higher specific heat due to these active forces.
<em>So this property helps to explain there is differences in forces between molecules.</em>
