Answer:
Hi
Explanation:
That's why rubbing your hands together makes them warmer. ... Friction causes the molecules on rubbing surfaces to move faster, so they have more energy. This gives them a higher temperature, and they feel warmer. Heat from friction can be useful.
Answer:
Electrons conducted heat
Explanation:
Iron is a metallic compound. One property of metallic compounds are that they have many loose electrons.
Consider the two rods to be a singular rod, since they touch:
An uncountable number of electrons at one end of the rod are heated, so they gain kinetic energy. Those electrons then collide with other electrons, which energize those as well (although less), which is equal to adding heat. This is a pattern that will flow all the way through the rod.
Answer:
See explanation
Explanation:
A. Constitutional or structural isomers have the same molecular formula but different structural formulas.
B. Conformational isomers are compounds having the same atom to atom connectivity but differ by rotation about one or more single bonds.
C. Stereo isomers are compounds having the same molecular mass and atom to atom connectivity but different arrangement of atoms and groups in space.
I. Enantiomers are stereo isomers (optical isomers particularly) that are non-superimposable mirror images of each other.
II. Diasteromers are optical isomers that are not mirror images of each other.
Both diasteromers and enantiomers are types of optical isomers which in turn is one of the types of stereo isomers.
Stereo isomers differ from conformational isomers in that the arrangement of atoms in stereo isomers is permanent while conformational isomers results from free rotations in molecules about single bonds.
Answer:
The next high tide will happen at 6 pm.
Explanation:
The rotation of the Earth and the translation movement of the Moon (ie the Moon's movement around the Earth), in addition to the gravitational force, contribute to the formation of the tides. The high tide will occur on the face of the Earth which is facing / facing the Moon; the low tide will occur on the faces that are forming approximately an angle of 90 ° with respect to the Moon.
There are usually two periods of high tide and two periods of low tide over a day. The interval between high tide and low tide is approximately 6 hours.
Besides the gravitational force exerted by the Moon, the tide is also influenced by the gravitational force that the Sun exerts on the Earth. The influence of the Sun is smaller due to its distance, but it can also be noticed depending on the phase of the Moon.
Objects float on water because it has surface tension.
