The process by which a semipermeable membrane allows water molecules, small molecules, and ions to pass through while retaining large particles

The graph shows the distribution of energy in the particles of two gas samples at different temperatures, T1 and T2. A, B, and C represent individual particles.

Combustion of ethylene glycol leads to a change in internal energy (/DeltaU) of - 1189 kJ at 298 K. What is the corresponding change in enthalpy in kJ/DeltaH? HOCH_2CH_2OH (l) + 5/2 O_2 (g) → 2 CO_2 (g) + 3 H_2O (l) / DeltaU = - 1189 kJ
