Thread Content
This post was last edited by “Back to Cambridge” on September 28, 2016, at 09:29. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their basic knowledge of chemical engineering. Subsequently, series such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Engineering Thermodynamics”, and “Chemical Process Technology” will also be introduced. We hope for your active participation~~~ For the “Question of the Day” activity, answers can be viewed directly in the replies; however, the thread will be closed after one day! ! To encourage everyone’s continued participation this year! You get 3 wealth points for participating, and an additional 4 wealth points for answering correctly~~~ Short answer question: What is the purpose of the temperature control device on a chemical sampling rack?
To maintain a constant temperature of the substance, facilitating subsequent experiments?
A. Prevent burns from sampling C. Accelerate the reaction rate Answer: B B. Ensure accurate analysis results D. Avoid freezing and cracking in winter
