C. Walking on wet floors shows that Friction is undesirable
Hello!
This is false!! It is the other way around. They usually have a very high melting point. For example table salt is around 800deg C which is approx just under 1500deg F.
Hope this helps. Thank you
The fossil could get damaged and broken into smaller pieces. That is a way it could make it difficult to determine the fossils age.
Answer:
Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. ... The fire's heat causes molecules in the pan to vibrate faster, making it hotter. These vibrating molecules collide with their neighboring molecules, making them also vibrate faster.
Explanation:
Answer:
D. the polar liquid will have the higher boiling point, since its molecules have dipole-dipole interactions.
Explanation:
<em>Dipole-Dipole interactions</em> take place only between polar molecules.
They consist of attractions between the negative end of a polar molecule and the positive end of another polar molecule. For example, between the O atom and the H atom in water.
These attractions are not present in a non-polar liquid, so its molecules will be more loosely held together and its boiling point will be lower.
