Answer:
When the heat is raised (for instance, as water is boiled), the higher kinetic energy of the water molecules causes the hydrogen bonds to break completely and allows water molecules to escape into the air as gas. We observe this gas as water vapor or steam.

Hello from MrBillDoesMath!
Answer:
The equations "are balanced"
Discussion:
Given that
4 + 4 = 8 => subtracting k from both sides
4 + 4 - k = 8 -k
so the equation shown IS correct. The answer should be the equations "are balanced"
Thank you,

Answer:
27
Step-by-step explanation:
To find the average change in elevation, you have to make it a unit rate. So we find that 378/14=27
Use a system of equations.
(x=# of small dogs, y=# of big dogs)
x+y=9 (times by -5) -5x-5y=-45
5x+8y=51
Then add the equations together and the x's cancel.
3y=6
y=2
So he walked 2 big dogs and 7 little dogs.
