The homologous structures and the analogous structures of different species.
Answer:
D - water changes from a
Explanation:
You're correct!
We are asked what happens when the pressure changes from 0 atm to 10 atm at 0C.
If we look at the graph at 0C on the x axis and at 0 atm on the y axis, we can see we are in the yellow area of the graph, so the water starts at a gas.
If we keep the temperature the same, but change the pressure to 10 atm (much higher on the y axis) we are in the blue area, so the water is now a liquid. Therefore, D is correct
The arrows that represent the phase transitions in which heat energy is gained is : (A). 1, 2 and 3
<h3>Meaning of phase transitions</h3>
Phase transitions can be defined as the changing of matter from one form to another due to the addition or gaining of heat or due to the removal or loss of heat.
Phase transitions in matter are majorly between three phases which are: Solid, Liquid and Gas.
In conclusion, The arrows that represent the phase transitions in which heat energy is gained is : (A). 1, 2 and 3

All atoms that are considered as alkali metals have one valence electron on the outermost shell.
In a mixture, we can separate the elements or compounds inside easily by using physical methods, such as filtration, evaporation, distillation etc.
However, a compund is two or more elements chemically combined together, so we cannot separate them using physical methods, only with checmicals methods such as apply heat or electricity (electrolysis)
