Answer:
A. The speed is unchanged.
Explanation:
In the case when the work is to be done on a particle i.e. zero so the change made in KE of the particle would be zero. This represent the work energy theroem. But when the KE remains same or does not change so it should be the same and the particle speed would also the same
Therefore as per the given statement, the first option is correct
And rest of the options are wrong

Answer:
The van der wall forces are existed between separate molecules of water but not between the hydrogen and oxygen molecules.
Explanation:
<em>Van der wall forces include repulsion and attraction between the atoms, surfaces and molecules.</em> <em>The intermolecular forces are also included in the van der wall forces. Basically, van der wall forces are the forces that are formed between molecules of the same molecules but not with the different molecules of the same substance.</em> Take water molecules into consideration,<em> van der wall forces exist between the water molecules but these forces are not associated between hydrogen and oxygen molecules. </em>These forces are fragile than ionic bond and covalent bond.
