The solubility of the gas is reduced when thermal energy is added to the solution, which overcomes the forces of attraction between the solvent molecules and the gas molecules.
Just consider it from a straightforward angle. Is it true that heating a solvent accelerates evaporation? Which glass will entirely evaporate first, at a temperature of 25 or 75 degrees, if you place the same amount of water in them both?
Gases are already inherently gases. Imagine how anxious gas molecules would be to escape if solvent molecules were to want to escape from the bulk solvent when the temperature was raised.

Answer:
A.
Explanation:
hope this helped sorry if its wrong!
Answer:
The correct option is: It becomes one-half as large.
Explanation:
The energy stored in a capacitor is inversely proportional to the distance between plates.
If the plate separation (distance between plates) is doubled, it means the Energy stored will be halved. That is, the energy stored becames one-half as large.
Explanation:
Principle Quantum Numbers : It describes the size of the orbital and the energy level. It is represented by n. Where, n = 1,2,3,4....
Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...
s = 1 orbital
p = 3 orbitals
d = 5 orbitals
f = 7 orbitals
For n = 4
l = 0 to (n-1) = 0 to 3 = (4s , 4p , 4d , 4f)
Number of subshells = 4
Number of orbitals = 1 + 3 + 5 + 7 = 16
The maximum number of electrons the n = 4 shell can contain:
Each orbital can holds upto two electrons, then 16 orbitals will have :
32 is the maximum number of electrons the n = 4 shell can contain
Answer:
The specific heat capacity of sand is less than the water.
Explanation:
On hot days, the beach sand gets hot than water because the specific heat capacity of water is higher than the sand.
Specific heat capacity:
"The amount of heat require to raise the temperature of one gram of substance by one degree"
it mean that water require more heat to raise the temperature while sand get hot by absorbing small amount of temperature.
The specific heat capacity of water is 4200 J Kg-1 °C-1
The specific heat capacity of sand is 840 J Kg-1 °C-1
Equation:
C = Q/ ΔT
Here C is the heat capacity, ΔT is the change of temperature of substance by absorbing heat and Q is the energy in joule.
Another equation:
Q = C× m × ΔT
m is the mass of given substance. The specific heat capacity of water very high than other substances that make a water compound in term of temperature.
