True/False questions: (Answer format: True True True True False) Question 3 is repeated from issue 33; since some members have already answered it, changes cannot be made. Please understand! 1. Gases of equal volume contain the same number of molecules. 2. The main factors affecting gas density are temperature and pressure. 3. The boiling point of a fluid is related to atmospheric pressure; as pressure increases, the boiling point rises. 4. The fluid exits from the same container, passes through two parallel pipes, and returns to the same container; the energy loss of the fluid in these two pipes is equal. 5. When a centrifugal pump leaves the factory, its nameplate indicates the relevant parameters of the pump; generally, these parameters are determined through tests using diesel as the working medium.
