is a physical change. The popsicle is still a popsicle even if its freezed, nothing has changed with it but its physical appearance :)
In a physical change some of the physical properties of the substance may be altered and the chemical composition?
In a physical change, the chemical composition of the substance remains the same, but some physical properties like shape, size, or state may change. This means that the substance can be reversed back to its original state without undergoing a chemical reaction.
A metal melts at 450 degrees celsius is the property of the metal classified as chemical or physical property?
chemical. when it melts, it doesn't mean it changed into a new substance. it just changed physical states! it is still a metal. physical state is a physical property of any substance, so when it changes physical state, as in changes to liquid, solid or gas, it is still the same substance.
What is a change that alters a substance without changing it into another substance?
Many physical changes will not alter the identity. However, some physical changes, such as heating or cooling will result in phase changes and so the identity will be different. While ice and water are chemically the same, they are not identical forms of the substance.

What is the physical changes in matter?
Physical changes in matter are when physical properties are changed. Some physical properties are size and color. When a physical change in matter occurs, the material may have changed size (gotten smaller) due to weathering and erosion. Chemical changes are when the chemical composition of a substnce is changed. For example a chemical change would be iron turning into rust due to the process of oxidation
How long the string be on a parachute?
The 'best' length for a parachute string depends on what the parachute is for and the rest of the design. If a parachute's strings are too short, the whole parachute could collapse. If the parachute's strings are too long, there may be some wobbling and bungeeing about, more twisting of the strings, etc. Parachutes for heavy things (like spacecraft) tend to have longer strings than parachutes for people, since they're less affected by this instability.
Did the Atomic bomb at Hiroshima drop by parachute?
No parachute, it was a barometric fuse. The parachute spotted by some survivors on the ground was a live telemetry sensor package dropped by the lead aircraft.

What evidences a physical change?
"A physical change occurs when some of the properties of a material change, but the substances in the material remain the same." "...any actions that change the size and shape of a material, but not its composition." if the shape/form is changed but not its makeup, then that change is physical
