Which best describes the transition from gas to liquid?

a) energy must be removed because particles in liquid move more slowly.

b) energy must be added because particles in liquid move more quickly.

c) energy is neither added nor removed in this phase transition.

d) energy is either removed or added, depending on the type of particles.

a) the kinetic energy decreases as in a gas, the particles are widespread and move freely but in a liquid, their movement is more limited

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
