A Fixed mass of gas omits 250J at heat energy and contracts at constant pressure of Ix10 Pa from 2.5 from 2.5x10^3m^3 to 1.0x10^-3m^3. what is the change in internal energy U?

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
