My science text book said that it was either diamond or gold. Gold may not be right, but I am pretty sure diamond is.
Sorry if I got this wrong.
Answer:
Freezing point: <u>32 ºF (0ºC)</u>
Melting point: <u>32 ºF (0ºC)</u>
Boiling point: <u>203°F (95°C)</u>
Explanation:
At the boiling point, <u>the vapor pressure of a liquid equals the external pressure</u>. The normal melting point and boiling point of water at 1 atm are 0°C and
100°C, respectively. Decreasing the pressure under 1 atm (what happens when we are at high altitudes) will lower the boiling point since the external pressure will be lower, and it will become equal with the vapor pressure at a lower temperature.
However, the melting point and freezing point will stay unaffected since they don't depend on air-pressure; so at 0 or 5000 meters they will still be 0°C (remember that, <u>since water is a pure substance, the freezing and melting points will be the same</u>).
Answer:
B
Explanation:
The solubility depends on the ksp. As the value of ksp increases the compound becomes more and more soluble.
In the options, the highest ksp value is 10^-10, thus that one is the most soluble.
There are 60 seconds in one minute
565900 / 60 = 9431.667 minutes in 565,900 seconds
There are 60 minutes in an hour
9431.667 minutes / 60 = 157.9144 hours in 565900 seconds
There are 24 hours in 1 day
157.9144 hours / 24 hours = 6.5498 days.
