Why is gas able to flow? a its particles have melted and can move around b its particles have high viscosity and can move around c its particles have enough energy to move around d its particles have enough pressure to move around 3. which of the following is true about the viscosity of liquids? a liquids with high viscosity do not flow as well as liquids with low viscosity b liquids with high viscosity flow better than liquids with low viscosity c liquids with high viscosity do not resist flow any more than liquids with low viscosity d water is a good example of a liquid with high viscosity 4.in a( the particles form a regular, repeating pattern ! ?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)

When an object is heated it contracts. a. true b. false
