Answer:
Some stars in space can come to life causing humans to be amazed but at thesame time in great/critical danger.
Complete Question
Consider a system consisting of an ideal gas confined within a container, one wall of which is a movable piston. Energy can be added to the gas in the form of heat by applying a flame to the outside of the container. Conversely, energy can also be removed from the gas in the form of heat by immersing the container in ice water. Energy can be added to the system in the form of work by pushing the piston in, thereby compressing the gas. Conversely, if the gas pushes the piston out, thereby pushing some atmosphere aside, the internal energy of the gas is reduced by the amount of work done.
![pV=nRT](https://tex.z-dn.net/?f=pV%3DnRT)
so the absolute temperature T is directly proportional to the product of the absolute pressure p and the volume V,Here n denotes the amount of gas moles,which is a constant because the gas is confined and R is the universal constant
What is the
as the system of ideal gas goes from point A to point B on the graph recall u is proportional to T
Answer:
![\triangle T=0](https://tex.z-dn.net/?f=%5Ctriangle%20T%3D0)
![\triangle V=0](https://tex.z-dn.net/?f=%5Ctriangle%20V%3D0)
The gas A and B have same internal energy
Explanation:
From the question we are told that
![Pa=u atm\\Va=1m^3\\Pb=1 atm\\Vb=4m^3](https://tex.z-dn.net/?f=Pa%3Du%20atm%5C%5CVa%3D1m%5E3%5C%5CPb%3D1%20atm%5C%5CVb%3D4m%5E3)
Generally the equation of temperature is mathematically given as
![Ta=\frac{Pv}{nR}](https://tex.z-dn.net/?f=Ta%3D%5Cfrac%7BPv%7D%7BnR%7D)
![Ta=\frac{u*1}{nR}](https://tex.z-dn.net/?f=Ta%3D%5Cfrac%7Bu%2A1%7D%7BnR%7D)
And
![Tb=\frac{PbVb}{nR}](https://tex.z-dn.net/?f=Tb%3D%5Cfrac%7BPbVb%7D%7BnR%7D)
![Tb=\frac{u*1}{nR}](https://tex.z-dn.net/?f=Tb%3D%5Cfrac%7Bu%2A1%7D%7BnR%7D)
Generally the change in temperature
is mathematically given as
![\triangle T=Tb-Ta=Tb=\frac{u*1}{nR}-\frac{u*1}{nR}](https://tex.z-dn.net/?f=%5Ctriangle%20T%3DTb-Ta%3DTb%3D%5Cfrac%7Bu%2A1%7D%7BnR%7D-%5Cfrac%7Bu%2A1%7D%7BnR%7D)
![\triangle T=0](https://tex.z-dn.net/?f=%5Ctriangle%20T%3D0)
Generally the change in internal energy ![\triangle V](https://tex.z-dn.net/?f=%5Ctriangle%20V)
![\triangle V=nC_v \triangle T\\](https://tex.z-dn.net/?f=%5Ctriangle%20V%3DnC_v%20%5Ctriangle%20T%5C%5C)
![\triangle V=0](https://tex.z-dn.net/?f=%5Ctriangle%20V%3D0)
Therefore with
![\triangle T=0](https://tex.z-dn.net/?f=%5Ctriangle%20T%3D0)
![\triangle v=0](https://tex.z-dn.net/?f=%5Ctriangle%20v%3D0)
The gas A and B have same internal energy
Answer:
3.45×10⁻⁴mm (or 0.000345mm)
Explanation:
Use a method called dimensional analysis here. It involves a chain of conversions, so we'll need some conversions to work with.
- 1nm = 1×10⁻⁹m
- 1mm = 1×10⁻³m
- 345nm; which is given
If you knew the conversion from nanometers to millimeters then you could just do it in one step. But I don't, so I won't. Anyways, you put the conversions into fraction form like so:
And then orient them in a way where multiplying the two (or more in other instances) gives you the units you want. In this cas it's millimeters so you'll have:
(345nm)•(1×10⁻⁹m/1nm)•(1mm/1×10⁻³m)
Notice how all the units reduce except for mm. From here you just multiply across and should get 345×10⁻⁶mm which simplifies to 3.45×10⁻⁴mm.
Newtons are used to measure force

chemical element whose atomic nucleus contains a specific number of neutrons in
addition to the number of protons that distinctively defines the element. The
nuclei of most atoms have neutrons as well as protons.</span>
