If 250(ft)3(s)-1 of air at 122(°f) and approximately atmospheric pressure is preheated for a combustion process to 932(°f), what rate of heat transfer is required?

Over the last 90 years, scientists have added to the body of evidence supporting the big bang theory. what is the latest piece of evidence discovered in 2014?

How does a noncompetitive inhibitor reduce an enzyme’s activity?

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
