Pressure
Explanation:
Pressure is a measure of force per unit area.
Pressure is defined as the force exerted on a body across a unit area. The unit of pressure is N/m² or Pascal.
Pressure = 
The more the force acting on a body the more the pressure felt. A small surface area and a large force increases pressure on a body.
it is right to say that pressure is proportional to force but inversely proportional to area.

Answer:
LiCl because the total negative charge on Cl is one.
Explanation:
Lithium has a charge of 1+ and Chlorine has a charge of 1-.
<span>The answer is B. Convection occurs when hot/warm
water rise to the top and the cold water goes to the bottom in a vessel. This is
because hot/warm water is less dense than cold water. Additionally, convection
currents are well perceptible in air and water and fluid substances that are
poor conductors of heat</span>
You have to use the equation q=mcΔT and solve for T(final).
T(final)=(q/mc)+T(initial)
q=the amount of energy absorbed or released (in this case 868J)
m=the mass of the sample (in this case 15.6g)
c= the specific heat capacity of the substance (in this case 2.41 J/g°C)
T(initial)=the initial temperature of the sample (in this case 21.5°C)
When you plug everything in, you should get 44.6°C.
Therefore the final temperature of ethanol is 44.6°C
I hope this helps. Let me know if anything is unclear.
13 atoms are in the chemical formula AI(PO4)3
hope that helps :-)
