Tanks of compressed gas must be kept away from heat sources. if the temperature of the tank increases too much, it may explode and cause a great deal of damage. which of the following best explains why a tank of compressed gas can explode if it is heated? . a. as the gas is heated, the molecules break apart into individual atoms and move apart. b. as the gas is heated, the molecules move faster and spread out from each other. c. as the temperature of the gas increases, the molecules release energy and move faster. d. as the temperature of the gas increases, the molecules gain energy and move sl

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.
