What else can I help you with?
What is the figure of speech in the expression he was out like a light?
To be knocked unconscious or fall asleep almost instantly. It comes from switching off a light. It goes out instantly too.
What is difference between optical rotation and specific optical rotation?
Optical rotation is the turning plane of linearly polarized light as it travels through certain materials. Specific rotation is the property of a chemical compound as the change in orientation of a plane of light.
The chemical composition of a star can best be determined by?
Analyzing its a light with spectroscopy
Change hhr tail light bulb?
What is the part number for the 2008 HHR tail light bulbs and backup light bulbs?
Is fire hollow?
No, fire is not hollow. Fire is a visible manifestation of combustion, which produces heat and light as a result of chemical reactions between a fuel and an oxidant, typically oxygen in the air. It consists of hot gases, glowing particles, and energy, but it doesn't have a physical structure or space inside that could be described as hollow.
Is a light bulb on a chemical or physical change?
Physical change
Is the production of light a chemical or physical change?
physical
Is emission of light a chemical or physical change?
Most of the time the emission of light is a physical change but there are some chemical reactions which emit light as a byproduct of the reaction.
Is production of heat or light a physical or chemical change?
Its a chemical change hottie
Is flash cameras flashing a chemical or physical change?
The flash of a camera is a physical change, not a chemical change. A physical change is a change in the form of a substance without changing its chemical composition. In the case of a camera flash, electrical energy is converted into light energy, which is a physical process that does not alter the chemical makeup of the components involved.
Is combustion a physical change?
NO its a chemical change for it can't be reversed
Is heat light and change in odor indicate a physical change?
Heat, light, and change in odor can indicate a physical change depending on the context. For example, melting ice into water is a physical change because it does not alter the chemical composition of the substance. However, if a substance undergoes a chemical reaction that results in heat, light, and change in odor, then it would be considered a chemical change.
Is the generation of light by an electric lamp a chemical or physical change?
This is a physical change. When the electrons go through the filament (or gas), there is no chemical change, only the physical change of temperature. The electricity to power the light may be generated chemically (fossil fuels or batteries) or from a hydroelectric plant. The light from "glow sticks" is an example of light generated by chemical changes.
Is light a physical property ora chemical change?
It is a physical change at least that is what I've been told
What kind of change occurs when you light a fire. A physical change or chemical change?
Both !
Is giving off light a physical or chemical change?
I would think it to be a Physical Change. Not chemical.
Is lighting a chemical or physical change?
Lighting is a physical change, not a chemical change. When a light switch is turned on, the flow of electricity through the bulb causes it to emit light, which is a physical reaction. No new substances are formed during this process.
