Q1. 1.Tell me about your self What Is ph . It's range
Ans. 
pH is a measure of the acidity or alkalinity of a solution. It ranges from 0 to 14.
• pH stands for 'potential of hydrogen'

• It is a logarithmic scale that measures the concentration of hydrogen ions in a solution

• A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline

• Examples: Lemon juice has a pH of around 2, while baking soda has a pH of around 9

Q2. What is partial pressure
Ans. 
Partial pressure is the pressure exerted by a single gas in a mixture of gases.
• Partial pressure is proportional to the mole fraction of the gas in the mixture.

• It is calculated by multiplying the total pressure of the mixture by the mole fraction of the gas.

• Each gas in a mixture contributes to the total pressure independently.

• Dalton's law of partial pressures states that the total pressure of a gas mixture is equal to t...read more

Q3. What is Ideal gas law
Ans. 
Ideal gas law is a fundamental law of physics that describes the behavior of gases under varying conditions.
• It relates the pressure, volume, temperature, and number of particles of a gas.

• The law is expressed as PV = nRT, where P is pressure, V is volume, n is the number of particles, R is the gas constant, and T is temperature.

• The law assumes that the gas particles are in constant random motion and that there are no in...read more
