Answer : The temperature in degree Celsius and Kelvin is, respectively.
Explanation :
The conversion used for the temperature from Fahrenheit to degree Celsius is:
where,
= temperature in Fahrenheit
= temperature in centigrade
The conversion used for the temperature from degree Celsius to Kelvin is:
where,
= temperature in Kelvin
= temperature in centigrade
As we are given the temperature in Fahrenheit is, 130
Now we have to determine the temperature in degree Celsius.
Now we have to determine the temperature in Kelvin.
Therefore, the temperature in degree Celsius and Kelvin are,
The process that took place is called oxidation or burning where wood was burnt into ashes.
<h3><u>
Explanation:</u></h3>
Wood is an organic compound formed of different types of carbohydrates, proteins and lipids. These components do have carbon oxygen hydrogen as most abundant atoms and also has some amount of nitrogen, phosphorous, and other metal ions like magnesium, calcium etc.
When the logs were burnt, the chemical reaction took place between the atmospheric oxygen and the atoms present in the wood, forming different oxides. As carbon was the most abundant atom present, a huge smoke containing carbon dioxide and carbon monoxide evolved. The hydrogen became the water vapour, and other gases were also formed like nitrogen dioxide, sulphur dioxide etc. These gases went off into atmosphere. The rest that were left behind were mixture of unburnt part of wood as well as the solid metal oxides. There were unburnt particles of carbon mixed with them too.
Earth contains huge quantities of water in its oceans, lakes, rivers, the atmosphere, and believe it or not, in the rocks of the inner Earth. Over millions of years, much of this water is recycled between the inner Earth, the oceans and rivers, and the atmosphere. This cycling process means that freshwater is constantly made available to Earth's surface where we all live. Our planet is also very efficient at keeping this water. Water, as a vapor in our atmosphere, could potentially escape into space from Earth. But the water doesn't escape because certain regions of the atmosphere are extremely cold. (At an altitude of 15 kilometers, for example, the temperature of the atmosphere is as low as -60° Celsius!) At this frigid temperature, water forms solid crystals that fall back to Earth's surface.
Many people live faraway from freshwater sources. They need to carry their water home.
While our planet as a whole may never run out of water, it's important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world's freshwater can be found in only six countries. More than a billion people live without enough safe, clean water.
Also, every drop of water that we use continues through the water cycle. Stuff we put down the drain ends up in someone or something else's water. We can help protect the quality of our planet's freshwater by using it more wisely.
Water because it's a polar and hexane which is a nonpolar solvent
Elements are substances that are made up of the same atoms which are capable of taking part in a chemical reaction.
There are different types of elements which are represented by symbols gotten from the first letter or the first and any other letter in the name of the element.
Examples of elements include:
When two or more of these elements combine together through a chemical bond, it leads to the formation of compounds.
Example of a compound includes:
- NaCl: The element sodium combine, through electrochemical bonding, with another element chlorine to form the compound sodium chloride.
