Constant: it is a red color water, and heat.
Input:  It’s heat. 
Output: The gas come out. 
What change: The temperature change, and water state( Liquid- Gas ).
Boundary of system: It happened in the flask, and the heat that heat in to containers. 


I will explain pictures.
As you can see the picture it has 4 state that I drew. The first state is not things, just water in the containers. Second state is we give the heat to containers, and water evaporates, then on top we put rubber and tube to let the air come out. Third states, we switch on the top of containers to bowl of water, so water sure in from the bowl. So it make heat energy release. And the last state is result. There is no heat and just have water from the bowl.]]> 2021-11-18 11:35:02 UTC https://padlet.com/thanyathornr2023/aarredvkb0h0i6bh/wish/1899280100 19/11/2021 thanyathornr2023 https://padlet.com/thanyathornr2023/aarredvkb0h0i6bh/wish/1901239976 We talk about gas law.

     * Because the collision are different. Example there have a temperature, concentration, and surface area. It depends on the concentration of the reactant. ( If increase aqueous concentration = Increase collision = increase reaction rate, If decrease of a gases = increases collision = increases reaction rate). the exposed surface area of the reactants it only for the solids ( Increased collision = increased reactant rate, increased surface area = increase collisions = increase reactant rate), also the temperature ( increase collision = increase reactant rate, increase temperature = increase collision = increase reactant rate) and pressure is only for gases  and if there is a catalyst present in the reactions.

    * spontaneous is a performed or occurring as a result of a sudden inner impulse or inclination and without premeditation or external stimulus. And it reaction by itself without energy. It like proceed its own.

We used same sized  of cups, but difference between amount of water. The reason for this is because speed of running. The speed of running is affect to pour more water in the box and to suck more water. 
    2. For seconds trial we used different size of cup ( bigger size and smaller size). As you use your nonsense you can guess that the bigger sizes will win. Because we can suck more water. And when the water is to low the bigger will not suck more water in to the cups because the water is not deep enough to suck in. 
    3. Last one we used different sizes of cup and different amount of water. The bigger sizes of cups has more water, but the smaller size uses less water. But the result is bigger sizes is win because as you know the bigger size has a lot of water to suck in to the cups to pour in the box.

    2. Why reaction of NaOH of can is differently? It about the aluminium or what?
    3. Is it possible that the HCl acid is less PH which it will make less reaction or not?
    4. If we have high Base like NaOH which means the reaction will more on can?
    5. Did the color or type of chemical coating affects to the can or not?]]>     2022-04-20 11:34:53 UTC https://padlet.com/thanyathornr2023/aarredvkb0h0i6bh/wish/2150172465     2. A/B rxn - What happens when an acid and base react with each other? (a) Write a 1 sentence description (b) Write a generic equation that represents all acid-base reactions (c) Write a real example reaction equation. (posted 4/21) thanyathornr2023 https://padlet.com/thanyathornr2023/aarredvkb0h0i6bh/wish/2152159680  1. When the acid and bases react with each other they will producing the salt. Because when the hydrogen + (H+) cation of the acid combined with OH- ( hydroxide -) is anion of the base to produce water. Which mean the compound of the cation and anion will make a salt. Also it equal to neutralize.
