Pressure Energy

In a horizontal oil pipeline of constant cross-sectional area the pressure decrease between two point 300 km apart is 5000 pascal (1 pascal = 1 newton per square meter). What is the loss of energy per unit volume per unit distance? [Hint : Loss in energy =(P_(1))/(rho)-(P_(2))/(rho) because (P)/(rho) is pressure energy per unit mass and loss in energy per unti volume =P_(1)-P_(2) .]

Electrostatic Pressure || Energy Density || Examples on Potential

Variation OF Gibbs Free Energy With Pressure and Temparature || Relation OF Gibbs Free Energy and Equilibrium Constant

Assertion :- If pressure greater than atmospheric pressure is applied to pure water or solution, its water potential decreases. Reason:- Pressure other than atmospheric pressure leads to decrease in free energy of solution

Excess Pressure and Surface Energy

Relation Between Pressure And Kinetic Energy

Variation of gibbs free energy with Pressure & Temperature || Gibbs free energy and equilibrium constant || Variation of gibbs free energy with reaction progress

Consider the quantities, pressure, power, energy impulse, gravitational potential, electoral charge, temperature, area, Out of these, the only vector quantities are.

Assertion: At absolute zero temperature, vapour pressure, kinetic energy, and heat content of the gas reduce to zero. Reason: At absolute zero, temperature velocity reduces to zero.
