Answer:
The five assumption of Kinetic molecular theory are given below.
Explanation:
Kinetic molecular theory of gasses stated that,
1) Gases consist of large number of smaller particles which are distance apart from each others.
2) The gas molecules collide with each other and also with wall of container and this collision is elastic.
3) Gas molecules are in continuous random motion and posses kinetic energy.
4) The forces of attraction between gas molecules are very small and considered negligible.
5) The temperature of gas is directly proportional to average kinetic energy of gas molecules.
Answer:
3. doubles
Explanation:
for an ideal gas behavior, the relationship between volume and temperature is given by Charles law
Charles law states that the volume of a given mass of gas is directly proportional to its temperature provided that pressure remains constant. Mathematically, this is represented as
V ∝ T
V=KT
K = V/T
where V is the volume of the gas
T is the Temperature
k represents the constant of proportionality
For initial and final conditions of a gas,
= 
where 1 and 2 represent initial and final conditions respectively
therefore, T₁ = 100 and T₂ = 200
= 
200 × V₁ = 100 × V₂
divide both sides by 100
2V₁ = V₂
final volume,V₂ = 2V₁
there the volume doubles
7.04×10^14 is the frequencyof light by the relation:
wavelength= wave velocity/frequency
<span>Fluorine
For the group 17 elements (Halogens), the ionization energy decreases as the period increases (the elements become less reactive). And since of the 4 elements given, fluorine is from the lowest period, it has the highest ionization energy.</span>
