Dmitri Mendeleev invented the periodic table.
<u>Answer:</u> The volume of balloon at 100°C is 4.46 L
<u>Explanation:</u>
To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Hence, the volume of balloon at 100°C is 4.46 L
Acid and bases both are the substances that cause corrosion. They can be differentiated on the basis of properties and pH.
If the pH is less than 7.0 the solution is acidic while if its value is greater than 7.0 it is the basis solution.
Examples:
Acid
Acetic acid has pH value 2.4
Sulphuric acid has pH value 0 for 1M solution
Base
pH of ammonia solution is 11
