What is the name of a process that contains information to proceed only in one direction but then information is lost such that it cannot be reversed?
Its called hashing. An example of such process is MD5 and SHA. For more information look it up.
What do irreversible mean?
Irreversible means something that cannot be undone or changed. In physics, it refers to a process that cannot be reversed to return to the original state.
How can one determine if a process is reversible or irreversible?
A process is reversible if it can be reversed without any loss of energy or increase in entropy. One way to determine if a process is reversible is to see if it can be undone by making small changes to the system. If the process cannot be undone without some loss of energy or increase in entropy, then it is irreversible.
What is involved in every chemical change?
One substance changing into a completley different substance. It cannot be reversed.
What is the largest number of eight digits with one of its digits 0 and remains the same when its digits are reversed?
An eight digit number with one zero cannot remain the same when its digits are reversed. It must have an even number of 0s.
Is transferring graphite from pencil to paper when writing a chemical or physical change?
physical change. You know that it is a physical change because it can be reversed. An example of a chemical change would be cooking an egg. Because you cannot reverse the process.
What is the difference between reverse process and equilibrium?
A reversible process is one which can be reversed and causes no changes in the system or surroundings. For a process in equilibrium, the rate of the forward process equals the rate of the reverse process (which can be, but is not necessarily equal to zero).
Who discovered how to riped sliced apples after turning brown?
No one. Apples cannot be ripened once they are sliced. The browning that occurs on sliced apples can only be prevented or delayed, it cannot be reversed.
How is sour milk a chemical change?
When milk turns sour, it is a chemical change because the bacteria in the milk ferment the lactose sugar into lactic acid, which changes the composition of the milk. This process cannot be easily reversed, making it a chemical change rather than a physical one.
What are some quotes from Rosalind Franklin?
"Science and everyday life cannot and should not be separated." "The question of how the structure of the protein molecule is related to the function of the living cell is one of the great questions of biology." "Science and everyday life cannot and should not be separated." "Knowledge only progresses if it is based on evidence. We cannot progress by simply making a guess, and then defending our guess with emotional rhetoric."
What is happening in the air or atmosphere at one time in one place?
Climate, because weather is an everyday process. Weather and weathering are everyday cycles. During those cycles there are rocks being broken down and the atmosphere changes overtime.
Which one life process can an adult do which a young child cannot?
