Answer:
Water/H20 is a compound made of hydrogen and oxygen. Although water is the most abundant substance on earth, it is rarely found naturally in its pure form. Most of the time, pure water has to be created. Pure water is called distilled water or deionized water.
Explanation:
Answer:
Heat flux = 13.92 W/m2
Rate of heat transfer throug the 3m x 3m sheet = 125.28 W
The thermal resistance of the 3x3m sheet is 0.0958 K/W
Explanation:
The rate of heat transfer through a 3m x 3m sheet of insulation can be calculated as:
![q=-k*A*\frac{\Delta T}{\Delta X}\\\\q=-0.029\frac{W}{m*K}*(3m*3m)*\frac{12K}{0.025m} =125.28W](https://tex.z-dn.net/?f=q%3D-k%2AA%2A%5Cfrac%7B%5CDelta%20T%7D%7B%5CDelta%20X%7D%5C%5C%5C%5Cq%3D-0.029%5Cfrac%7BW%7D%7Bm%2AK%7D%2A%283m%2A3m%29%2A%5Cfrac%7B12K%7D%7B0.025m%7D%20%20%3D125.28W)
The heat flux can be defined as the amount of heat flow by unit of area.
Using the previous calculation, we can estimate the heat flux:
![heat \, flux=\frac{q}{A}=\frac{125.28 W}{9 m^{2} } =13.92 W/m^{2}](https://tex.z-dn.net/?f=heat%20%5C%2C%20flux%3D%5Cfrac%7Bq%7D%7BA%7D%3D%5Cfrac%7B125.28%20W%7D%7B9%20m%5E%7B2%7D%20%7D%20%20%3D13.92%20W%2Fm%5E%7B2%7D)
It can also be calculated as:
![q/A=-k*\frac{\Delta T}{\Delta X}](https://tex.z-dn.net/?f=q%2FA%3D-k%2A%5Cfrac%7B%5CDelta%20T%7D%7B%5CDelta%20X%7D)
The thermal resistance can be expressed as
![\Delta T=R_t*Q\\R_t=\Delta T/Q=\frac{\Delta X}{k*A}](https://tex.z-dn.net/?f=%5CDelta%20T%3DR_t%2AQ%5C%5CR_t%3D%5CDelta%20T%2FQ%3D%5Cfrac%7B%5CDelta%20X%7D%7Bk%2AA%7D)
For the 3m x 3m sheet, the thermal resistance is
![R_t = \frac{\Delta X}{k*A}=\frac{0.025m}{0.029W/mK*9m^{2}}=0.0958 \, K/W](https://tex.z-dn.net/?f=R_t%20%3D%20%5Cfrac%7B%5CDelta%20X%7D%7Bk%2AA%7D%3D%5Cfrac%7B0.025m%7D%7B0.029W%2FmK%2A9m%5E%7B2%7D%7D%3D0.0958%20%5C%2C%20K%2FW)
Answer:
![\boxed{\sf Volume \ of \ plastic \ used = 10.14 \ cm^3}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%5Csf%20Volume%20%5C%20of%20%5C%20plastic%20%5C%20used%20%3D%2010.14%20%5C%20cm%5E3%7D%20)
Given:
Mass = 14.0 g
Density (
) = 1.38 g/cm³
To Find:
Volume (V)of the plastic used to make water bottle
Explanation:
Formula:
![\boxed{ \bold{Density \ (\rho) = \frac{Mass \ (m)}{Volume \ (V)}}}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%20%5Cbold%7BDensity%20%5C%20%28%5Crho%29%20%3D%20%5Cfrac%7BMass%20%5C%20%28m%29%7D%7BVolume%20%5C%20%28V%29%7D%7D%7D)
Substituting value of m & density in the formula:
![\sf \implies 1.38 = \frac{14.0}{V} \\ \\ \sf \implies V = \frac{14.0}{1.38} \\ \\ \sf \implies V = 10.14 \ cm^3](https://tex.z-dn.net/?f=%20%5Csf%20%5Cimplies%201.38%20%3D%20%20%5Cfrac%7B14.0%7D%7BV%7D%20%5C%5C%20%20%5C%5C%20%20%20%5Csf%20%5Cimplies%20V%20%3D%20%20%5Cfrac%7B14.0%7D%7B1.38%7D%20%5C%5C%20%20%5C%5C%20%20%20%5Csf%20%5Cimplies%20V%20%3D%2010.14%20%5C%20cm%5E3%20)

Volume of the plastic used to make water bottle = 10.14 cm³
Answer: glass is not considered as solute.
Extra's:
A solute is a substance that gets dissolved in a solvent. ... The solutes in air are oxygen, argon, and carbon dioxide gas, as well as water vapour.
Sugar is a solute in the solvent water. Sugar is one of the most soluble solutes in water.
Also solute is a powder that can be dissolved in solvent like water. here baking soda is a solute.
