Find the temperature at which ethanol boils on a day in the mountains when the barometric pressure is 547 mmhg. (given: the heat of vaporization of ethanol is 39.3 kj/mol; the normal boiling point of ethanol is 78.3°c; (r = 8.314j/ k • mol).

Which of these describes how heat is transferred by convection* a. sunlight travels through space without the aid of fluids or solids. b. warm air rises and takes the heat with it, eventually, it cools and sinks c. air at the equator rises and sinks at the poles. d. air molecules touch the warm ground, heating them up *not conduction
