Answer to: The first law of thermodynamics is expressed in the equation, Delta H = q + w. (a) True (b) False By signing up, you'll get thousands of...
Section 2 deals with the principle of conservation of energy - the first law of thermodynamics. This principle states that in an isolated system, the sum of all energies remains constant during energy conversion processes. The following energies are dealt with in more detail: mechanical energy (...
A. be created B. be destroyed C. only be transferred or transformed D. none of the above 相关知识点: 试题来源: 解析 C。中文解析:根据文章内容,第一定律即能量既不能被创造也不能被毁灭,只能从一种形式转化或转移为另一种形式。反馈 收藏 ...
