Final answer:
An object that cannot be altered after it is constructed is considered immutable. The Second Law of Thermodynamics and the concept of conservation of mass embody this principle in various scientific contexts, as well as in discussions of sustainability and biological growth.
Step-by-step explanation:
The type of object that cannot be altered after it is constructed is referred to as being "immutable". This concept is applicable in various contexts, including computer programming and physical science. In the context of thermodynamics and physics, the Second Law of Thermodynamics suggests that energy transfer from a cold object to a hot object does not spontaneously happen. Similarly, objects can undergo irreversible changes, such as when an object is destroyed and cannot be restored to its original state, as with Man Ray's Object to Be Destroyed.
Conservation of mass is another principle in physics where the mass remains constant in a closed system, demonstrating an immutable property in the context of matter. When it comes to human constructs and sustainability, modern constructs are often not immutable as they do not withstand the test of time due to a lack of harmony with the planet's limits. Lastly, biological processes such as the growth of an acorn into an oak tree represent immutable changes; the acorn can never revert back to its original form once it has changed.
