MEASUREMENT AND MATTER Interconverting temperatures in Celsius and Kelvins The metal osmium becomes superconducting at temperatu

nexus9112 [7]

Answer: $-272^0C$ .

Explanation:

Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like $^0C$ and $K$

These units of temperature are inter convertible.

We are given:

Temperature of the gas = $655mK=0.655K$ (1mK=0.001 K)

Converting this unit of temperature into $^0C$ by using conversion factor:

$(t-273.15)^0C=tK$

$273.15K=0^0C$

Thus $0.655K=(0.655-273.15)^0C=-272^0C$

Thus the temperature is $-272^0C$ .

Jimmy developed a model to show the difference between pure substances and mixtures

IrinaK [193]

Pure substances cannot be separated into any other kinds of matter, while a mixture is a combination of two or more pure substances.
A pure substance has constant physical and chemical properties, while mixtures have varying physical and chemical properties.

<u>Explanation:</u>

A matter which cannot be separated into any other kind of matter using the chemical or physical process is called pure substances. A pure substance has the same color, composition, and texture.
An element consisting of a single compound with a definite composition, physical and chemical properties are called pure substances.
A combination that has as of many substances that are not united using a chemical procedure or any process is known as mixtures. A mixture does not exist in fixed proportions, and most of the natural substances are mixtures.
