First, the water must be raised to a temperature of 100 degrees - this requires 4.181 joule/(degree x gram). For example, if your "room temperature" is 20 degrees, multiply that by 8.Then you have to actually evaporate it - that costs 2260 joules/gram.
Answer:
3.25×10²⁴ molecules.
Explanation:
From the question given above, the following data were obtained:
Number of mole of CO₂ = 5.4 moles
Number of molecules of CO₂ =?
The number of molecules of CO₂ in 5.4 moles can be obtained as follow:
From Avogadro's hypothesis,
1 mole of CO₂ = 6.02×10²³ molecules
Therefore,
5.4 moles of CO₂ = 5.4 × 6.02×10²³
5.4 moles of CO₂ = 3.25×10²⁴ molecules
Thus, 5.4 moles of CO₂ contains 3.25×10²⁴ molecules.
Answer and Explanation:
Meteorologists use meteorological data to assess current temperature and precipitation rates and even make projections of these rates in future times. If high temperature rates combined with low rainfall can cause catastrophic fires to occur, then analyzing data on these factors and making projections on them is essential to prepare for those fires.
