If i use a certain amount of energy/work - let's say 0,36 J - to wind up an old alarm clock, will the mass of the clock increase, or will the clock just get hotter somehow?

The amount of energy/work used to wind something depends on the resistance of the object being wound. The higher the resistance, the more energy/work is required to wind it. However, if the object has low resistance, less energy/work is needed.
Yes, the law of conservation of energy states that energy cannot be created or destroyed, but it can be converted into different forms. In the case of winding, the energy/work used is converted into potential energy stored in the wound object.
It depends on the context. In general, 0.36 J is a relatively small amount of energy/work. However, it can be significant if it is used to power small devices or if it is repeatedly applied over time.
Friction can increase the amount of energy/work needed to wind something. This is because friction creates resistance, which requires more energy/work to overcome. Lubricants can reduce friction and therefore decrease the amount of energy/work needed for winding.
Yes, energy/work can be measured using a variety of units such as joules, foot-pounds, or calories. A device called a dynamometer can measure the amount of force applied during winding, which can then be used to calculate the amount of energy/work used.
