0.2396 g/ml × 20.0 ml = 4.792 g
Explanation:
mass = d x v
Explanation:
A process in which water vapor changes into liquid state is known as condensation. As we know that when energy is released in a reaction then it is known as exothermic reaction and when energy is absorbed in a reaction then it is known as endothermic reaction.
As vapors have high energy so, when they change into liquid state then heat energy is released by them. Therefore, condensation is an exothermic reaction.
As per Le Chatelier's principle, any disturbance caused in an equilibrium reaction will tend to shift the equilibrium in a direction away from the disturbance.
So, when there will occur a decrease in temperature then molecules of a gas will come closer to each other. Hence, there will also occur a decrease in vapor pressure of the gas.
Hi , here's the definition:
Cycloalkanes are cyclic hydrocarbons , meaning that the carbons of the molecule are arranged in the form of a ring.

Answer:
A. Water changes from a gas to a liquid to a solid.
Explanation:
We can see the following points in the diagram:
- Point A: water starts at 0.5 atm and 100°C, so it is vapor (gas).
- Point B: water changes from vapor to liquid.
- Point C: water changes from liquid to solid.
- Point D: water as a solid reaches a temperature of -10°C.
So, water changes from a gas to a liquid to a solid.
