GSP Crop Science Production Supervisor Interview Questions and Answers

Q1. What are endothermic and exothermic reactions?
Ans. 
Endothermic reactions absorb heat, while exothermic reactions release heat during the process.
• Endothermic reactions require energy input, often in the form of heat.

• Example: Photosynthesis, where plants absorb sunlight to convert CO2 and water into glucose.

• Exothermic reactions release energy, usually as heat or light.

• Example: Combustion of fuels, like burning wood or gasoline, which releases heat.

Q1. What is heat transfer type
Ans. 
Heat transfer types include conduction, convection, and radiation.
• Conduction is the transfer of heat through direct contact between objects or substances.

• Convection is the transfer of heat through the movement of fluids or gases.

• Radiation is the transfer of heat through electromagnetic waves.

• Examples of conduction include touching a hot stove or holding a metal spoon in hot soup.

• Examples of convection include boiling w...read more

Q2. What is distillation
Ans. 
Distillation is a process of separating components of a liquid mixture based on their different boiling points.
• Distillation involves heating a liquid mixture to vaporize the more volatile components.

• The vapor is then cooled and condensed back into a liquid, resulting in the separation of the components.

• The component with the lower boiling point will vaporize first and be collected separately.

• Distillation is commonly us...read more

Q3. What type of fire hydrant cylinder use in chemicals fire. Ans mechanical foam cylinder.
Ans. 
Mechanical foam cylinders are commonly used in chemical fires for their ability to quickly suppress flames by forming a blanket of foam.
• Mechanical foam cylinders are effective in suppressing fires involving flammable liquids and chemicals.

• The foam generated by these cylinders helps to smother the fire by cutting off the oxygen supply.

• These cylinders are typically used in industrial settings where there is a higher risk...read more

Q4. What is the pressure of water in fire hydrant water tank. Ans 7 kg
Ans. 
The pressure of water in a fire hydrant water tank is typically around 7 kg.
• The pressure in a fire hydrant water tank is measured in kilograms per square centimeter (kg/cm^2)

• This pressure is necessary to ensure that water can be quickly and effectively sprayed onto a fire

• The pressure may vary depending on the specific location and regulations

Q5. What is the moving position of acm mill Ans Anti clock wise.
Ans. 
The moving position of an acm mill is anti-clockwise.
• ACM mill rotates in an anti-clockwise direction to perform milling operations.

• The anti-clockwise rotation helps in achieving the desired milling results.

• It is important to ensure the correct direction of rotation for efficient milling process.

Q2. Types of reaction and their control Cooling tower and types.
Ans. 
Different types of reactions include exothermic, endothermic, reversible, and irreversible. Cooling towers are used to remove heat from industrial processes.
• Exothermic reactions release heat and require cooling to prevent overheating.

• Endothermic reactions absorb heat and require heating to maintain the reaction.

• Reversible reactions can go in either direction depending on the conditions.

• Irreversible reactions only proce...read more
