Answer:
Following are the solution to the given question:
Explanation:
The material is necessary to cook since frying is a speedy process for evaporation.
Drug A is now in the compressed fluid area, and the material would not boil if the pressure is chilled. Because the ship is solid, its substance A claim is false.
Unless the volume comprises of a drop in the heat, the B substance reaches a vapor pressure area and a wet region. That's the area that melting may occur. His claim for material B could therefore be true.
Answer:
C
Explanation:
N = Na.P/A------(1)
Na = avogadro's number = 6.02210²³
P = density
A = atomic weight of metal
When we substitute into equation 1 above we get
1.0x10²⁹atoms/m³
From here we calculate the number of vacancies
T = 1000⁰c = 1273K
The formula to use is
Nv= Nexo(Qt/K.T) -----(2)
Qt = 1.22eV
K = Boltzmann's constant = 8.6210x10^-5
When we substitute values into equation 2
We get Nv = 1.49 x 10²⁴m-3
Therefore option c is correct
