Bose Einstein condensation occur at temperature very close to absolute zero i.e 273.15 degrees centigrade.. Under such conditions, large quantity of Boson occupies the lowest quantum state, at which point microscopic quantum phenomena becomes apparent macroscopically. A BEC is formed by cooling a gas of extremely low density about one hundred thousandth the density of normal air, to ultra low temperature.
Answer:
The correct option is (c).
Explanation:
Given that,
Mass of iron, m = 3 kg = 3000 g
The temperature of ice increases from 20°
C to 25°C.
The specific heat of iron is 0.45 J/g°C
We need to find the energy required to raise the temperature. The formula is given by :
So, 6750 J of energy is required to raise the temperature or iron.
There are 4 quantum numbers that can be used to describe the space of highest probability an electron resides in.
First quantum number is the principal quantum number- n , states the energy level.
Second quantum number states the angular momentum quantum number - l,
states the subshell and the shape of the orbital
values of l for n energy shells are from 0 to n-1
third is magnetic quantum number - m, which tells the specific orbital.
fourth is spin quantum number - s - gives the spin of the electron in the orbital
here we are asked to find l for 3p1
n = 3
and values of l are 0,1 and 2
for p orbitals , l = 1
therefore second orbital for 3p¹ is 1.
Answer:
1.78 M⁻²s⁻¹
Explanation:
Let's consider the following reaction:
A + B → C + D
The reaction order for A is 1 and the reaction order for B is 2.
The rate law is:
r = k.[A].[B]²
where,
r is the rate of the reaction
k is the rate constant
[A] and [B] are the molar concentrations of the reactants
Then, we can find the value of k.
