Which of these physical changes would require the addition of energy

The physical change which would require the addition of energy is boiling a liquid.

Explanation:

Physical changes mostly indicate the change in the state of matter of every element. As physical changes does not affect the chemical properties or composition of the element, the nature of the bonding will be same. But it will undergo a change in the structure and shape or in other words, it will undergo a change in the state of matter.

As it is known that there always occurs an inter conversion between different states due to physical changes. So the inter conversion includes, boiling of liquid to gas, freezing of liquid to solid, condensation, deposition etc.

Among the given options, boiling requires additional energy from the surrounding to break the bonds of the liquid and to convert to gaseous state. Thus, the endothermic reaction or the physical change which would require the addition of energy is boiling a liquid.

ill try to . no promises tho.
