When a gas is cooled, the particles begin to move /slowly). when the temperature drops below (melting point/boiling point), the substance's particles have condensed and formed a liquid. if the liquid is cooled down even more, the amount of thermal energy in the particles /decrease), and the liquid's temperature will continue to decrease. eventually, the substance will freeze and form a solid. if the temperature continues to (increase/decrease), the particles in the solid (vibrate in place/move around one another) more slowly.

Wave functions describe orbitals in a hydrogen atom. each function is characterized by 3 quantum numbers: n, l, and ml. if the value of n = 2: the quantum number l can have values from to . the total number of orbitals possible at the n = 2 energy level is .

Examples of states of consciousness include a. daydreaming b. dreaming during sleep c. hypnosis d. all of the above

Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.
