Answer:

Types of indicators which show if the solution is an acid , alkali or a natural

Explanation:

You add one of two drops of the indicator into a solution and then it would be in a scale from red to purple and this is called a PH scale which shows if it's an acid, alkali or a natural solution red being a strong acid with the PH number of one , green being a natural solution with the PH number of 7 and an alkali being purple with the PH number of 14

Hope this helps :)

Having been heated to 800 K , at some point the tank starts to leak. By the time the leak is repaired, the tank contains only ha
Liula [17]

Answer: The temperature of the gas reduced to 400K.

Explanation:

Stated that ; The pressure remains the same, that is initial and final pressure equals 1atm.

Applying Charles Law

V1/T1 = V2/T2

Initial volume V1 = 1

Final volume V2 = 1/2 (halved)

Initial temperature T1 =800K

Final temperature T2 = ?

(1/800) = (1/2)/T2

T2 = 800/2

T= 400K

Therefore, when the volume is halved, the temperature reduced also to half ( 400K)

Olenka [21]

<u><em>on the basis of the reaction of heat in plastic , their are two types of plastics : </em></u>

<h2><u><em>Thermoplastic & Thermosetting plastics </em></u></h2>

<u><em>Thermoplastics : Plastics which easily get deformed (become soft )on heating and also get bend easily are known as thermoplastics . </em></u>

<u><em>examples :  polythene , polyvinyl  chloride and polystyrene .</em></u>

<u><em>thermosetting plastics : plastics which once moulded into a shape do not become soft on heating and cannot be moulded again are called thermosetting plastics .</em></u>

<u><em>examples : bakelite , melamine and formica</em></u>
