Whose law states that the volume of a gas varies inversely with the absolute pressure, as long as the temperature remains constant? A. Charles' B. Boyle's C. Newton's D. Dalton's
Which of the following statement(s) is(are) correct? Group of answer choices A. N B. The pressure, volume, and temperature of the steam are not connected by simple equations unlike ideal gases. C. An irreversible adiabatic process is a constant entropy process. D. The vaporization process of steam is isobaric in nature. E. The general energy equations for ideal gas are analogous to the equations for the processes of vapors.
True or False: the Reynold's analogy holds true when v = DAB
Choose correct answer: The temperature before and after the adiabatic process is 200 K and 127°C. The pressure before the process is 500000 N/cm2 and adiabatic index is 2.4, then its pressure after the process is approximately 800000 N/cm2 Select one: True False

A team of professional thieves wants to knock down a castle wall using a primitive explosive. At theirheadquarters, they determine that the explosive has a mass of 40.0 kg and will break into three pieces: a 20.0 kgpiece will go exactly east, a 10.0 kg piece will go exactly south, and a 10.0 kg piece will go somewhere. Find thespeed and direction of the third piece of the explosive.
