If the amount of energy requird in the process X to `X^(-)` is `-5 kJ//"mole"` then calculate how many energy is required in X to `X^(-)` process

When water is heated to a temperature x, it gets converted into steam at temperature x by a process called R. And when steam at temperature x is cooled, it gets reconverted into water at the same temperature x by a process called S. (a) How much is the value of x in Kelvin ? (b) What is the process R called ? (c ) What is the name of the energy absorbed during the process R ? (d) What is process S known as ? (e) What is the name of energy released during the process S known as ?

X amount of energy is required to remove an electron from its orbit and Y amount of energy is required to remove a nucleon from the nucleus.

The amount of energy required to remove the electron from a Li^(+2) ion in its ground state is x times that of the amount of energy required to remove the electron from an H-atom in its ground state find .x.

When water is cooled to a temperature x, it gets converted into ice at temperature x by a process called P. And when ice at temperature x is warmed, it gets reconverted into water at the same temperature x in a process called Q. (a) What is the value of temperature x in Kelvin ? (b) What is the process P known as ? (c) What is the name of energy released during process P ? (d) What is the process Q known as ? (e) What is the name of energy absorbed during process Q ?
