No. A Bendy Straw is simply light being refracted as it passes from the air into the water. There is no form of change occurring, just simply the bending of light. Because light travels the fastest in a vacuum (about 300,000,000 ms^-1), but significantly slower in water ( 225,056,264 ms^-1), the light slows radically as it enters the water. To disperse this energy, the light bends to wards the normal, which is perpendicular to the horizontal waters surface. It is this slowing of the light that you see as a Bendy Straw.
Physical.
It is called a phase change.
physical change are reversable
If form changes but identity doesn't change then it is a physical change.
change in the form -in general can be indicated for the physical form. The substance may dissolve or its stage may change. If the change is physical, it should be reversable.
It is a physical change.
This process is called physical change the answer to that is physical change!!!
A change in matter that changes its physical form is called a physical change. This type of change does not alter the chemical composition of the substance, but only its physical properties such as shape, size, or state (solid, liquid, gas).
The process of juice freezing and forming popsicles is a physical change. This is because the change in state from liquid to solid is a physical change that can be easily reversed by allowing the popsicle to thaw back into liquid form.
physical
When a cube of ice melts to form water, it undergoes a physical change. This is because the substance remains water in both states, but changes from a solid form (ice) to a liquid form (water) due to a change in temperature.
It is a physical change. It is still the same substance.
