Oxygen turns into a liquid at -183 Celsius
to get the oxygen to such a lower temperature, the gas is compressed and then cooled 
uranmaximum [27]2 years ago
3 0
Oxygen is like a milder form of nitrogen when it comes to its changing forms.

Oxygen becomes a gas when heated above -183 degrees Celsius, and when it is cooled below -183 degrees Celsius, it becomes a liquid. 

Just as a bonus, the transition between liquid and solid forms happens when Oxygen is cooled below -218.79 degrees Celsius.

So your answer is "the conversion between the liquid and gaseous states of Oxygen." :)

A child bounces a 48 g superball on the sidewalk. the velocity change of the superball is from 26 m/s downward to 17 m/s upward.
Nataly_w [17]
By definition we have the momentum is:
 P = m * v
 Where,
 m = mass
 v = speed
 Before the impact:
 P1 = (0.048) * (26) = 1.248 kg * m / s
 After the impact:
 P2 = (0.048) * (- 17) = -0.816 Kg * m / s.
 Then we have that deltaP is:
 deltaP = P2-P1
 deltaP = (- 0.816) - (1,248)
 deltaP = -2,064 kg * m / s.
 Then, by definition:
 deltaP = F * delta t
 Clearing F:
 F = (deltaP) / (delta t)
 Substituting the values
 F = (- 2.064) / (1/800) = - 1651.2N
 answer:
 the magnitude of the average force exerted on the superball by the sidewalk is 1651.2N

As the particles in a soup reach the boiling point what do you expect to happen
Marysya12 [62]
As the particles in a soup reach the boiling point, the kinetic energy of the molecules will start increasing and ultimately bubbles will be created in the soup and it will slowly start to vaporize. Boiling point of a liquid is the temperature at which the vapor pressure of the liquid will become equal to the atmospheric pressure.<span> </span>

a small object with a charge of magnitude q creates an electric field. at a point 1.0 m to the north of the charge the field has
Sunny_sXe [5.5K]

We have that for the Question,it can be said that the field has a <u>value </u>of

  • E_B=12N/C due west

From the question we are told

a small object with a charge of magnitude q creates an electric field. at a point 1.0 m to the north of the charge the field has a value of 2.0 n/c directed south. at a <em>point </em>0.5 m to the west of the <em>charge </em>the field has a value of

<h3> Electric field </h3>

Generally the equation for the <em>electric</em> field   is mathematically given as

E=\frac{q}{4\piE_0r^2}

Therefore

if E_A=3N/C\\\\E_B=\frac{3}{0.25}\\\\\frac{q}{4\piE_0}=3N/C\\\\

  • E_B=12N/C due west

Explain what it is meant by redshifted
pantera1 [17]
The displacement of spectral lines toward longer wavelengths (the red end of the spectrum) in radiation from distant galaxies and celestial objects. This is interpreted as a Doppler shift that is proportional to the velocity of recession and thus to distance.
