Evaporation is a physical change. You can tell by the fact that when somthing evaporates, its chemical identity does not change. The only thing that changed is its physical properties.
Answer : The temperature in degree Celsius and Kelvin is,
respectively.
Explanation :
The conversion used for the temperature from Fahrenheit to degree Celsius is:
![^oC=(^oF-32)\times \frac{5}{9}](https://tex.z-dn.net/?f=%5EoC%3D%28%5EoF-32%29%5Ctimes%20%5Cfrac%7B5%7D%7B9%7D)
where,
= temperature in Fahrenheit
= temperature in centigrade
The conversion used for the temperature from degree Celsius to Kelvin is:
![K=273.15+^oC](https://tex.z-dn.net/?f=K%3D273.15%2B%5EoC)
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.
![^oC=(^oF-32)\times \frac{5}{9}](https://tex.z-dn.net/?f=%5EoC%3D%28%5EoF-32%29%5Ctimes%20%5Cfrac%7B5%7D%7B9%7D)
![^oC=(130^oF-32)\times \frac{5}{9}](https://tex.z-dn.net/?f=%5EoC%3D%28130%5EoF-32%29%5Ctimes%20%5Cfrac%7B5%7D%7B9%7D)
![^oC=54.44](https://tex.z-dn.net/?f=%5EoC%3D54.44)
Now we have to determine the temperature in Kelvin.
![K=273.15+^oC](https://tex.z-dn.net/?f=K%3D273.15%2B%5EoC)
![K=273.15+(54.44^oC)](https://tex.z-dn.net/?f=K%3D273.15%2B%2854.44%5EoC%29)
![K=327.59](https://tex.z-dn.net/?f=K%3D327.59)
Therefore, the temperature in degree Celsius and Kelvin are, ![54.44^oC\text{ and }327.59K](https://tex.z-dn.net/?f=54.44%5EoC%5Ctext%7B%20and%20%7D327.59K)
Answer:
Some natural resources like sunlight and wind are found everywhere, but other natural resources are unevenly distributed. Resources like oil, coal, and natural gas are only found where conditions were favorable to grow and preserve large quantities of animal or plant matter.
Explanation:
Answer:
0.029
Explanation:
Initially, the number the student intends calculating is 29:
From 29 x ![\frac{N}{c^{2} m^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BN%7D%7Bc%5E%7B2%7D%20m%5E%7B2%7D%20%7D)
but a submutiple of a thousand was introduced in form of mc²:
this implies:
29 x( 1/
)
:
to make the expression correct: 29 should be 0.029
0.029 x ( 1/
) ![\frac{N}{c^{2} m^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BN%7D%7Bc%5E%7B2%7D%20m%5E%7B2%7D%20%7D)
