The change in pressure over a given distance is defined as a pressure gradient. The strength of this pressure gradient determines how fast the wind moves from higher pressure toward lower pressure. A stronger pressure gradient will cause stronger winds, as shown in Figure 2. >> Balanced in the vertical by the force of gravity
Answer:
New pressure P2 = 4.95 atm
Explanation:
Given:
Old volume V1 = 1.50 L
New volume V2 = 0.50 L
Old pressure P1 = 1.65 atm
Find:
New pressure P2
Computation:
P1V1 = P2V2
So,
(1.50)(1.65) = (0.50)(P2)
New pressure P2 = 4.95 atm
Explanation:
There is more solute than the solvent can hold (C).
Answer:
It decreases
Explanation:
As you go down a group from top to bottom, the electronegativity decreases. Across a period, electronegativity increases from left to right.
- Electronegativity is the tendency with which the atoms of the element attracts valence electrons in a chemical bond.
- The more electronegative an element is, the stronger its affinity for electrons.
- Electronegativity values less than 2 shows an element is a metal.
- Metals are generally electropositive.
