Find p2 if a gas changes from 25 oC and 87 kPa to 50 oC

What is the freezing point of radiator fluid that is 50% antifreeze by mass? kf for water is 1.86 ∘c/m.

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.

Ionic compounds can be readily dissolved in water because the high dielectric constant of water screens and decreases the force between the oppositely charged ions.
