What suggests that a physical change has taken place in a ice cube?

What variables do you use to calculate acceleration?
To calculate acceleration, you need to know the change in velocity (final velocity - initial velocity) and the time taken for that change to occur. Acceleration = (Change in velocity) / (Time taken).
Is cutting hair an example of a physical change and why?
Yes, cutting hair is an example of a physical change. It involves altering the appearance or state of the hair without changing its chemical composition. This change is reversible, as the hair can grow back.
Is using a dehumidifier for moisture a chemical or physical change?
No. It is a physical change.
Which physical quantity is given by slope of v-t graph?
The physical quantity given by the slope of a velocity-time graph is acceleration. This is because the slope represents the rate of change of velocity over time, which is how acceleration is defined (acceleration = change in velocity / time taken).
How do you know when a physical change is taking place?
The best way to know when a physical change is taking place is to observe. There will be a visible change in physical changes.

Is slicing turkey a physical or a chemical?
Slicing turkey represents a physical change, not a chemical change. The chemical composition of the sliced turkey is identical to the chemical composition of the intact turkey. Only a physical change has taken place.
Is metal cooled and taken out of a mold a physical or chemical change?
This would be a physical change because there is no change in the chemical make up of the metal and there is no creation of new substances there is simply a change in state for the metal.
When a cube of ice melts to form a puddle of water is it a physical change?
Yes. No chemical change has taken place, only a physical change. It can be undone (liquid water can be re-frozen)
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.

i know that its physical change because all you saliva is doing is making the food wet
Is slicing a banana a physical change or chemical change?
It's a physical change, because no chemicals are changing if I cut a banana.
What signs that a physical change has taken place in water?
hydrogen and oxygen gas are given off
Is a vase that gets broken a chemical change?
It is a physical change because it is the same vase but it is in tiny pieces
