Suppose you place a hot pack into a vacuum chamber and the hot pack caused the temperature to rise from 21 degrees to 23 degrees

Celsius. If the
pressure was initially 1 atmosphere, what equation would you use to determine the new pressure at the new temperature? Assume volume, and quantity of
gas are held constant.
Select one:
a. P1/T1 = P2/T2
b. P1V1 = P2V2
c. P1T1 = P2T2
d. P1n1 = P2N2

Answer: It showed that all atoms contain electrons.

Explanation:

  • J.J. Thomson's experiments inside a cathode ray tube in the presence of an electric field showed that all atoms contain tiny negatively charged subatomic particles "electrons".
  • Also, Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup."
  • Furthermore, Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny positively-charged nucleus.
  • Then, Rutherford proposed the nuclear model of the atom based on these results.

aksik [14]

The Intermolecular force is a type of force which exists between particles in an Ideal gas.

<h3>What  type of force which exists between particles in an Ideal gas?</h3>

Intermolecular forces are considered weaker attractions that hold molecules in gas close together. This force of attraction is present between molecules or particles.

So we can conclude that the Intermolecular force is a type of force which exists between particles in an Ideal gas.
