The noun 'flashlight' is a singular, common, compound, concrete noun; a word for a battery-operated portable electric light; a word for a thing.
It does depend on the kind of laser, but the main difference is that a laser emits a focused beam of light of the same wavelength (i.e. color) while a flashlight emits light of many different wavelengths, and 'beams' this light by reflecting it using a concave mirror built into it behind/around the bulb.
Physical properties. For example, how it looks, feels, smells, is it hard or soft, small or big, heavy or not? All the things that are visible to the eye. Hope this helps! :D
No and yes: No: 'substance' is a word like 'matter', so the amount or type of substance is a physical property. When comparing an object with another 'more substantial' object, the 'more substantial' object is more massive or somehow stronger, so mass or strength would be the physical property considered. Yes: Since substance is matter, something with substance has the property of being composed of some kind of matter (an atom) rather than being something else like purely energy (a photon) ... or perhaps thought (an idea).
Density is a physical property.

The density is the ratio between the mass and the volume. ---- It's a physical property.
physical change, because you are changing the physical property of the object. you are causing the change by hammering it. If you were to put some kind of chemical on it and it changed the physical property of the object that would be a chemical change.
Physical properties of matter.
The popular energy of flashlight are Rechargeable Li-on battery, Alkaline battery.
A physical property is a measurable characteristic of an item that is determined by its appearance. A sentence with it would be "More than one physical property of the substance changed when it became a gas."
it depends what kind flashlight you use, and the temperature has effection on it too.
The melting point and freezing point of water are physical properties.
