The air pressure in the rigid tank Decreases.

<u>Explanation:</u>

A rigid tank is said to be a region where volume is always considered as a constant. During the process of cooling the rigid tank where the temperature is said to be decreased, the effect of air pressure in the tank also decreases.

Because, PV = RT, where P is the pressure, T is temperature, R is constant, V is the volume. Hence pressure is directly proportional to temperature.

If the temperature in the tank is decreased this would imply that the kinetic energy of molecule decreases because of the ideal gas law:
PV= nRT (Since Pressure is directly proportional to Temperature).
So the answer is B.The air pressure in the rigid tank decreases.
Hope this helps you.

What is the definition of visible white light wave (RoyGBive)
uranmaximum [27]

There's no such thing as a wave of white light.  Every light wave with
a certain wavelength has some color.  White light is a mixture of all
the different wavelengths with all of the different visible colors. 
They're ALL there in white light.  When they all enter your eye at
the same time, your brain gets the message of brightness with
no particular color, which we call "white light".

How is temperature related to the physical change of a<br>substance​
blagie [28]

Answer:

~~Now, you have left your question very open ended and didn't ask for any particular kind of answer so I'll do my best to get what you're looking for.~~

A physical change in a substance doesn't change what the substance is. It can possibly melt or freeze an object. I mean heat makes things expand while cooling makes them retract.... In chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.

Your friend says that the force that the sun exerts on earth is much larger than the force that earth exerts on the sun. part a
Verizon [17]
I disagree with that opinion, and I have solid Physics to back me up.

The forces of gravity are always equal in both directions. The sun pulls the Earth with exactly the same force with which the Earth pulls the sun.

It may seem weird, but your weight on Earth is exactly the same as the Earth's weight on you. For the same reason.

Organisms that existed over a limited period

Explanation:

Index fossils are organisms that existed within a limited period in the geologic record.

These fossils are indicator fossils that serves as guide to define the relative ages of rocks in a sequence.

Here are some characteristics of index fossils:

  • they must have existed over a limited period in their history.
  • they must be very distinctive with short evolutionary tend.
  • they must be abundant and highly widespread in the stratigraphic column.
