That depends what you mean with "disappear". If you burn something, it might "disappear" in a sense. But it really gets converted to something else - and the smoke etc., plus the heat energy, have exactly the same mass (measured in kilograms, or pounds) as the original substances.
So, basically, the "law of conservation of mass" is taken to be valid, and the answer is "no".
No
Objects do not simply disappear without a reason. Nor can an object be made to appear without reason
Chemistry and physical science belong to physical science because they both have an object.For example in physics, you want to know how a roller coasters stay on track so the riders will not fall.It is physical science because it used an object,aroller coaster.In chemistry you use an object,liquids.You mix acids ,baces ectcetra.
PE in physics is Potential Energy which means: energy an object has because of the position, shape, or condition of the object. KE in physics is Kinetic Energy which means: the energy of an object that is due to the object's motion.
In physics, velocity is the measurement of the rate and direction of change in the position of an object.
The study of the structure of matters is the object of physics and chemistry.
Nobelium is only an object of studies in nuclear physics and nuclear chemistry laboratories.

Determined.
In physics, a push or pull on an object is called a force.
