Record your data and answer the conclusion question Radius of the tube in cmcm (slide 3-to find the radius measure the diameter of the capibillary tube using the cm ruler and divide by 2)

Temperature of gas (c) read the actual temperature on the thermometer

Height of the column of gas (cm) record the height of the gas at the bottom of the stopper.

Temperature of gas (k) k=C +273

Volume of gas (cm3)
V=r2h=3.14 r= radius of tube h=height of gas in tube your answer should have 2 significant digits.)

Ratio V/T ( cm3/K)

DIvide the volume by the temperature in K.

Your answer should have 2 significant digits

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
