Safety precautions based on physical properties just means that you do what you need to not to get hurt. This means you would wear a heat-resistant suit if you entered a burning building for example.

How does proximity sensor work?
Without physical contact detecting the presence of objects is the purpose of proximity sensors. They work based on inductive, magnetic, photoelectric and capacitive properties of objects.
What is the celsius scale properties based on?
The scale is based on the temperature at which water freezes and boils.
When a solid melts its density does not change very much. So why do a liquid and a solid have such different physical properties?
The physical properties are not mainly based on density. The main difference between a solid and a liquid is that in a solid, the forces between atoms or molecules are strong enough to keep them in place. As a result, the solid keeps its shape. ============================ When a solid melts its density changes a lot. The density is the amount of mass a body possesses per unit volume. In solids all the matter is compacted and crushed in a particular place more than a liquid. Its density varies a lot. And density cannot only be the sole characteristic of physical properties as explained by the former contributor.
The scale of temperature independent on thermal properties?
Only the Kelvin scale. The Celsius scale, for example is based on the thermal properties of water, as is the Reaumur scale. The Fahrenheit scale is based on the freezing point of brine, the freezing point of water and, possibly, the normal body temperature.
Describe the three types of temperature scales?
Celsius: Based on the properties of water where 0 is freezing and 100 is boiling. C= (F-32) *(5/9) Fahrenheit: Based on the properties of water where 32 is freezing and 212 is boiling. This worked out because 0 was set as the coldest it got, and 100 the hottest it got, at the place in Europe where Fahrenheit lived when he developed the scale. F=(C*9/5)+32 Kelvin: Based on the properties of matter where 0 is the absolute coldest temperature possible, using degrees of the same size as the Celsius scale. Kelvin = Celsius - 373.15 Rankine: Based on the properties of matter where 0 is the absolute coldest temperature possible, using degrees of the same size as the Fahrenheit scale. Rankine = Fahrenheit - 459.67
Can minerals be identified based on their physical and chemical properties.?
Yes
What are the earth's layers that are based on physical properties?
The Earth's Layers That Are Based on Physical Properties are:Okay here they are (from the outside to the inside)A. LithosphereB. AsthenosphereC. MesosphereD. Outer CoreE. Inner CoreThere are five layers based on physical and 3 based on composition they are:A. CrustB. MantleC. Core
Why are standard precautions used in addition to transmission based precautions?
Standard Based Precaution is the first step in implementing precautions, whether Transmission Based or Universal Based Precautions.
Is it true that unknown compounds can usually be identified based solely on their physical properties.?
it is not true that some compounds can usually be indetified based solely on their physical properties.
What is the separation of mixtures based on?
The physical properties of the things in the mixture. It could be that one part of the mixture is soluble, the other part insoluble - both physical properties. It could be that you use the boiling point of 2 liquids to separate them - physical properties. You could use a magnet if one part is magnetic and the other isn't - physical properties. And so on. But you are relying on physical properties rather than chemical properties.
Mendeleev attempted to organize the chemical elements based on their?
On chemical and physical properties
Is red color a physical or chemical properties?
The color is a physical property of materials but based on the chemical structure and composition.
The components of a mixture are mostly efficiently separated from one another based upon their?
Differences in physical properties.
What are the five layers of us based on physical properties?
We are all made out of a mass of molecules and a complex molecular structure.
Is the mantle divided into layers based on the physical properties?
no, it cant be the properties because the earth's mantle was thought to be different then what we think it is now. i am pretty sure it is where the sections are located at.
What are the chemical and physical property of paint?
Physical properties: paint is a thick colored liquid with a distinct smell. Chemical properties differ depending on the paint...poster paint, oil-based house paint and car paint have vastly different chemical properties, but they're all paint.
True or false Compounds can usually be identified based solely on their physical traits?
is it ture or falae that unknown compounds can ususally be identified based soley on their physical properties/
