Answer:

Explanation:

The current temperature and pressure at STP (Standard Temperature and Pressure) stated by IUPAC are:

Using the ideal gas equation, pV = nRT, and the Avogadro constant, you can find the volume occupied by 5.80 × 10²⁰ molecules.

$pV=nRT\\\\ \\ V=\dfrac{nRT}{p}$

$V=\dfrac{5.80\cdot 10^{20}molec\times \dfrac{1mol}{6.022\cdot 10^{23}molec}\times 0.08206\dfrac{atm.liter}{mol.K}\times 273.15K}{0.9869atm}$

$V=2.19e^{-2}liter=0.0219liter$

Answer : It is a conclusion.

Explanation:

Conclusion: It is a judgement or decision which can be attained by reasoning.

From the observation table given we can conclude that :

Aluminum ,bronze and steel took 27,45 and 80 seconds to melt small piece of wax respectively which means that more time will be required by them to transfer heat to the food while cooking. Hence, food will take more time to cook in them.

Copper took less time of 15 seconds to melt the small piece of wax in comparison to other metal pots which means that it is a good conductor of heat in comparison to other. Hence, copper pot would be better for cooking food quickly.

After analyzing the observations and results in an experiment conclusion was made that copper pots are best for cooking foods.
