Answer:
The electric force between them decreases
Explanation:
The force between two charged particle is given by :
Where
r is the distance between charges
If the distance between the charges is increased, the electric force gets decreased as there is an inverse relation between force and distance.
Hence, the correct option is (c) "The electric force between them decreases"
Hello!
Take for example the heating of water.
When heating liquid water from room temperature (25 °C) to the boiling point (100 °C), adding heat results in a direct increase in the temperature. This kind of heat is called sensible heat, because we can sense the effect of the added energy.
But when you reach 100 °C, there is a phase change from liquid to vapour, and the added heat is used to produce the phase change, and no increase in temperature is observed, only the phase change. This kind of heat is called latent heat.
Have a nice day!
Sheild volcanoes contain more water in it. It is a type of volcano that is built entirely of fluid lavas.
Answer:
a chemical change is a change that changes the substance into a whole new substance.
Examples include: burning wood, a banana peel rotting, milk souring, and even your food/drinks digesting.
Answer:
The pH of a 0.10 Maqueous Ba(OH)2 solution at 25°C is 13.30
Explanation:
The balanced equation is Ba(OH)2(s)→Ba2++2OH−
This indicates that the concentration is 0.2 M
We will find H+ ion concentration
As we know that
[H+][OH−]=1.0×10−14M
Given -
[OH−]=2.0×10−1M
Putting value of [OH-] in above equation we get -
[H+]=5.0×10−14M
pH=−log10[H+]
pH=−log10[5.0×10−14] = 13.30.
