<em>Nothing happens</em>; water is still H₂O, even if it turns into ice, or vapor. Although, the molecules still move around faster, just like a normal gas would.
Answer:
point 2 and 4
Explanation:
because at those point temperature is constant
Answer:
The correct answer is - 4 m/s
Explanation:
Given:
time = 20 sec
velocity= 80 m/s
Accelaration = ?
Solution:
formula for the accelaration can be drive from the for
vi = vf + ( a.t)
0 m/s (rest) = 80 m/s + (a.20s.-1)
a.20.-1= -80,
we check if this is true;
0 m/s= 80 + -80 = 0 so its true.
so a.20.-1= -80,
a= 80/20 ,
Thus, the correct answers a = 4 m/s
ionic bond
Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds.
As we know, Number of protons = Atomic Number
So,
And, Atomic mass = Number of protons + Number of Neutrons (N)
therefore ~
Number of Neutrons = 19
