At sea level, water ______________ at 100°C.
Answers
Answer:
boils
Explanation:
Vapour pressure of the liquid determines the temperature at which a liquid will boil. When water boils the pressure of the gas above it becomes equal to the vapour pressure of the liquid. This causes the inter-molecular bonds of water to break down and the water starts to evaporate. Water boils at 100°C at sea level however if you were to reach a higher altitude water would boil at a lower temperature as the air pressure will be lower.

Example: A frozen object (such as ice) is solid. Its molecules move extremely slow because the object itself isn't moving... It's like the skin on your bod... Imagine that wiggling and writhing on your bones. It's not like a gas, that can move freely and has no specific form or hold.
So again, the answer is Cold.

There's not enough information given to do that calculation.
-- The question doesn't specify whether the satellite is on the
shelf in the Vehicle Assembly Building before being installed
onto the booster, or inside the nose-cone as the rocket is slowly
being rolled to the launch-pad, or on its ascent to orbit after launch,
or in orbit. Its velocity in each of these situations is different.
-- The question reveals only the satellite's mass, but the answer
doesn't depend on that number. The satellite's velocity depends
on the speed of the truck or the rocket carrying it, or the size of
the orbit it's in. The question doesn't give any of these.
==> In particular, the size of a satellite's orbit, or its speed in that
orbit, DO NOT depend on its mass.
For example:
There are hundreds of TV satellites ... the ones that match the
Earth's rotation and appear motionless in the sky. They have
many different sizes, shapes, and masses, but they're all in the
same geostationary orbit, 22,000 miles above the equator, and
they all have the same average orbital velocity, zero displacement
per (23 hours 56 minutes 4 seconds).

Answer:
Electron orbitals are energy levels or shells that an electron inhabits in an atom or a molecule. The number of orbitals in an atom depends on the number of protons in its nucleus. The electrons fill the orbitals from lowest to highest energy. The arrangement of electrons in the orbitals determines the behavior and properties of the atoms and molecules.
