Q14: Our sun
Q15: The strong magnetic reaction in our atmosphere
Displacement is the distance and direction of an object's change in position from the starting.
Hence option B is correct.
Hope this helps!
Answer: The standard state refers to 1 atm and
.
Explanation:
It is known that a chemical/substance can either be present in a solid, liquid or gaseous state.
So, when the phase of a substance like solid, liquid or gas is present at 1 atmosphere pressure and at a temperature of
then it known as standard state of substance.
Thus, we can conclude that standard state refers to 1 atm and
.
The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. Therefore, the boiling point of a liquid depends on atmospheric pressure.
