The next day you make the same tea. But this time, rather than let it sit in your room temperature kitchen until it has reached 20°C, you put it in a 95°C oven. Then you oh-sogradually reduce the temperature inside your oven until both the oven and the tea are at 20°C. Calculate the entropy change of the tea and the entropy change of the air inside the oven as a result of the cooling of the tea. (Pay no attention to whatever mechanism is used to cool the

the question you provided is not complete

however here is the complete question

you make tea with 0.30kg of 95c water and  for some inexplicable reason let it cool to room temperature20C before drinking.

A) CALCULATE THE ENTROPY CHANGE OF THE WATER WHILE I COOLS

b) the cooling process is essentially isothermal, for the air in your kitchen. calculate the change  in entropy of the air while the tea cools, assumimng that all the heat lost by the water goes into the air. what is the total entropy change of the tea + air

c) The next day you make the same tea. But this time, rather than let it sit in your room temperature kitchen until it has reached 20°C, you put it in a 95°C oven. Then you oh-sogradually reduce the temperature inside your oven until both the oven and the tea are at 20°C. Calculate the entropy change of the tea and the entropy change of the air inside the oven as a result of the cooling of the tea. (Pay no attention to whatever mechanism is used to cool the oven. you are concerned with the interaction of the tea and air inside the oven.

Explanation:

check the attachment for answer and explanation

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

  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-
