According to the electron-cloud model of the atom, an orbital is a
(1) circular path traveled by an electron around the nucleus
(2) spiral path traveled by an electron toward the nucleus
(3) region of the most probable proton location
(4) region of the most probable electron location

According to the electron-cloud model of the atom, an orbital is a "region of the most probable electron location" In this mode, an electron can actually be in two places at once. 

Sorry i dont understand the question can you rephase it?

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
