d) To calculate air pressure, the volume occupied by air is assumed constant. Why is this incorrect? Explain how the vapor press
Aleks [24]

Answer:

the volume occupied by air is not constant because as we add ethanol in it it will keep decreasing.

vapor pressure calculated and clausius-Claperon plot are affected because volume and vapor pressure are directly proportional.

Explanation:

by charle's law volume and temperature are directly proportional and vapor pressure is directly proportional to temperature thus volume and vapor pressure are also directly proportional by  this relation

If Sarah melts 10g of tin. What mass of melted tin would she have at the end of the experiment?​
Nastasia [14]

Answer:

10g

Explanation:

As the Law of Conservation of Mass states that " Mass can neither be created nor be destroyed in a chemical reaction".

Though melting of tin isn't a chemical change, the same logic is applied here...

Hence,

The mass of tin will be 10 g itself...

1. How much electrical energy is needed to bring two charges Q1= 5.5 x 10-7C and Q2= 1.7 x 10-6 C from infinity to where they ar
kati45 [8]

Answer:

The electrical energy needed is 8.415*10⁻³ N

Explanation:

Energy is the ability of a body to make changes or work.

By separating or joining two electric charges a distance (for example, a radius r) within their electric fields, you are taking away or giving the electric charges energetic potentials, relative to each other. By releasing these charges, they will attract or repel each other, releasing that acquired electrical energy.

In other words, electric potential energy is linked to the particular configuration of a conglomerate of point charges in a defined system.

That is, it calculates the capacity of an electrical system to carry out a task based exclusively on its position or configuration. So, it is a kind of energy stored in the system, or the amount of energy that it is capable of delivering.

Thus, a charge will exert a force on any other charge and the potential energy is the result of the set of charges.

The electric potential energy that has a point charge q in the presence of another point charge Q that are separated by a certain distance r is:

Ep=K*\frac{Q1*Q2}{r^{2} }

where:

  • Ep is the electric potential energy. It is measured in Newton (N).
  • Q1 and Q2 are the values ​​of the two point charges. They are measured in Coulombs (C).
  • r is the value of the distance that separates them. It is measured in meters (m).
  • K is the constant of Coulomb's law. For vacuum its value is approximately 9*10⁹ N*m²/C²

In this case:

  • Q1=5.5*10⁻⁷ C
  • Q2=1.7*10⁻⁶ C
  • r=1 m

Replacing:

Ep=9*10^{9}\frac{N*m^{2} }{C^{2} }  *\frac{5.5*10^{-7}C *1.7*10^{-6}C }{(1m)^{2} }

Solving:

Ep= 8.415*10⁻³ N

<u><em>The electrical energy needed is 8.415*10⁻³ N</em></u>
