B) cooling And solidification of magma
Answer:
Explanation:
The question is asking, "At what temperature does the vapour pressure of water equal 3.4 atm?"
To answer this question, we can use the Clausius-Clapeyron equation:
Data:
p₁ = 1 atm; T₁ = 373.15C
p₂ = 3.4atm; T₂ = ?
R = 8.314 J·K⁻¹mol⁻¹
(The enthalpy of vaporization changes with temperature. Your value may differ from the one I chose.)
Calculation:
Answer: the number of a chemical element in the periodic system,
Explanation:
<span>the change in entropy is positive and change in enthalpy is negative.and potential energy is lower.and the reason is materials in nature naturaly want to get stabler and more chaotic.
for the second question there is a big formula.Equilibrium θ=mcθ1(water)+mcθ1(metal) /mc(water)+mc(metal) just put numbers and it is easy to solve.equlibrium temperture is 23.5</span>
Answer:
See explanation
Explanation:
Freezing point and melting point increases slightly at higher altitude
The boiling point decreases at higher altitudes.
Air pressure decreases with altitude As a result of this, atmospheric pressure decreases and water must now boil at a lower temperature. In order to compensate for this lower boiling point of water, food must take a longer time to cook. The lowering of air pressure actually means that the air becomes thinner at higher altitudes.
Pressure cookers cook food at high pressure thereby reducing the cooking time significantly. This helps to retain 50% of the nutrients in the food, lower the kitchen temperature and lower the energy cost required to cook food.
