Are all physical changes reversible with examples?
Not all physical changes are reversible because most times when such changes occur parts of the substance is lost to the environment.
What is a non reversible change?
A reversible change is a change you can make, then put back, however a non-reversible change is a change you can make, then it will be stuck like that
Why are most physical changes reversable?
Most physical changes are reversible because they involve only changes in the physical state or appearance of a substance, rather than its chemical composition. Reversible changes usually involve processes like melting, freezing, dissolving, or changes in shape, which can be easily reversed by applying the appropriate conditions to change the substance back to its original state.
Does hand soap have an reversible change or irreversible?
Most changes in hand soap are reversible, meaning it can go back to its original state. For example, if a solid bar of soap melts when heated, it can solidify again when cooled. However, if the soap is burned (irreversible change), it cannot return to its original form.
Is the freezing mercury reversible or irreversible physical change?
It is a physical change.
What do you call most changes that cannot be reversed?
irreversible
Is making crisps from cooking oil and potatoes a reversible change or chemical reaction?
Most cooking processes are chemical reactions. Generally, the reactions are non reversible and once cooked, food cannot be returned to an uncooked state. So, frying potatoes causes a non reversible chemical reaction. The question is not as precise as it might be. Changes can be physical or chemical. They can also be reversible or non reversible but it is important to note that many chemical changes are reversible just as many physical changes are reversible.
How is the physical change in the robot reversible and how can you tell that the change follows the law of conservation of mass?
The physical change in a robot is reversible if the change does not alter the molecular structure of the materials involved. If the robot is disassembled and reassembled, the change is likely reversible. One can tell that the change follows the law of conservation of mass by weighing the robot before and after the change. If the mass remains the same, then mass has been conserved.
Which types of dementia are potentially reversible?
Most dementia is incurable and irreversible. Forms of dementia that are reversible are caused by a tumor or impairment from drugs or medication.
Are all side effects of aromatase inhibitors reversible or are some irreversible?
Most side effects of aromatase inhibitors, such as joint pain, hot flashes, and fatigue, are generally reversible upon discontinuation of the medication. However, some effects, like bone density loss, can lead to irreversible changes if not managed appropriately. It’s essential for patients to discuss potential side effects and management strategies with their healthcare provider to minimize long-term complications.
How do you reverse a reversible ratchet wrench?
in most there is a small lever on the head. This changes the twist .
What happens to the characteristics of a substance during a physical change?
During a physical change, the characteristics of a substance such as size, shape, and phase may change, but its chemical composition remains the same. These changes are reversible and do not result in the formation of a new substance.
