Cohesion holds hydrogen bonds together to create surface tension on water. Since water is attracted to other molecules, adhesive forces pull the water toward other molecules.
Friction and gravity (both a function of weight and structure) will always stop an object. Assuming it’s a smooth ball those would be the two primary slowing components assuming no outside force such as like a bat hitting it :)
Before a titration, indicator is added to the analyte (which is in the flask, and usually the chemical of unknown concentration). The titrant is then placed in a burette and slowly titrated into the analyte. When the indicator changes color is when the endpoint of the titration has been reached. This occurs (approximately) at the equivalence point.
Answer:
The mass of the liquid = 162 g
Explanation:
As we know ,
Q = mc (ΔT)
where Q = Heat energy of the liquid
c = specific heat of the liquid
ΔT = change in temperature
m = mass of the liquid
As given , the temperature increases from 20.°C to 33°C,
⇒ ΔT = 33 - 20 = 13°C
Also given , c = 0.57 cal/g°C
Q = 1200 cal
∴ we get
1200 = (m)(0.57)(13)
⇒ 1200 = m(7.41)
⇒m = = 161.943 ≈ 162 g
So, we get
The mass of the liquid = 162 g
