1. Which type of ideal gas will have the largest value for C-Cp? (D) (A)Monatomic (B)Diatomic (C)Polyatomic (D)The value will be the same for all. Solution: The difference between the molar specific heat at constant pressure and that at constant volume is

I. Choose the Correct Answer 1. The magnitude of the force of gravity between two identical objects is given by Fo. If the mass of each object is doubled but the distance between them is halved, then the new force of between the objects will be

I. Choose the Correct Answer 1. Which of the following quantities are independent of the choice of inertial frame? (There may be more than one correct answer) (A)Velocity (B)Acceleration (C)Force (D)Work Solution: In all the inertial frame, the forces acted on a body are same,=ma=F'=ma', therefore the force and acceleration are independent of the choice of inertial frame

粘胶的最佳溶解条件是在20°C、13°Be (101.1g1)的烧碱中。湿进布织物或纱线有经历这 危险区的可能性,因此最好干进布。另外洗碱工艺 有所改变:要迅速用大量热水(50-80C)洗,以尽 可能快地通过危险区。粘胶在KOH中的溶胀小,所 以常采用 NaOH/KoH混合碱进行丝光处理。在NaOH 中加入40-50g/的NaC,可对粘胶起保护作用
