Q8. What is unit of pressure?
Ans. 
The unit of pressure is the pascal (Pa).
• The pascal is defined as one newton per square meter (N/m²).

• Other common units of pressure include pounds per square inch (psi) and atmospheres (atm).

• Pressure can also be measured in millimeters of mercury (mmHg) or torr.

• In engineering, pressure is often expressed in kilopascals (kPa) or megapascals (MPa).

Q9. What is ph range?
Ans. 
pH range refers to the scale that measures the acidity or alkalinity of a substance.
• pH range is a scale from 0 to 14.

• A pH value of 7 is considered neutral.

• Values below 7 indicate acidity, with lower values being more acidic.

• Values above 7 indicate alkalinity, with higher values being more alkaline.

• For example, lemon juice has a pH range of 2-3, making it highly acidic.

• Baking soda has a pH range of 8-9, making it slight
