Round 1 - One-on-one 

(8 Questions)

  • Q1. What are the differences between the fire point and flash point?
  • Ans. 

    Fire point is the temperature at which a fuel continues to burn after ignition, while flash point is the temperature at which a fuel produces a flammable vapor.

    • Fire point is higher than flash point.

    • Flash point is the minimum temperature at which a liquid gives off vapor in sufficient concentration to ignite.

    • Fire point is the temperature at which a fuel sustains combustion once ignited.

    • Flash point is used to classify fl...

  • Q2. What is the difference between flash distillation and fractional distillation?
  • Ans. 

    Flash distillation is a single-stage process where a liquid mixture is vaporized quickly, while fractional distillation is a multi-stage process where the mixture is separated into fractions based on boiling points.

    • Flash distillation is a rapid vaporization process used for separating components with large differences in boiling points.

    • Fractional distillation is a slower process that involves multiple distillation stag...

  • Q3. What is the difference between "flammable" and "inflammable"?
  • Ans. 

    The terms 'flammable' and 'inflammable' mean the same thing - capable of catching fire easily.

    • Both 'flammable' and 'inflammable' mean easily ignited and capable of catching fire.

    • The prefix 'in-' in 'inflammable' does not mean 'not' as in other words, but rather intensifies the meaning.

    • The use of 'inflammable' can sometimes cause confusion due to the misconception that it means 'not flammable'.

  • Answered by AI
  • Q4. What are the different types of permits related to safety?
  • Ans. 

    Different types of permits related to safety include building permits, fire permits, and health permits.

    • Building permits are required for construction, renovation, or demolition of buildings to ensure compliance with safety codes.

    • Fire permits are necessary for activities involving fire hazards, such as fireworks displays or bonfires.

    • Health permits are needed for businesses that handle food or provide health services to

  • Q6. What is the definition of toxicity, and what does LD50 refer to?
  • Q7. What is the theoretical plate height in packed bed and distillation columns?
  • Ans. 

    The theoretical plate height in packed bed and distillation columns is a measure of the efficiency of separation.

    • The theoretical plate height in packed bed columns is typically calculated using the HETP (Height Equivalent to a Theoretical Plate) equation.

    • In distillation columns, the theoretical plate height is a measure of the height of an idealized theoretical plate required for a given separation efficiency.

    • Theoretic...

  • Q8. What calculations are required to dilute a sodium hydroxide (NaOH) solution from 12% to 5%, and how much water should be added?
  • Ans. 

    To dilute a 12% NaOH solution to 5%, calculations involve using the formula C1V1 = C2V2 and determining the amount of water needed.

    • Use the formula C1V1 = C2V2, where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.

    • Calculate the volume of the initial 12% NaOH solution needed using the formula V1 = (C2 * V2) / C1.

    • Subtract the initial volume from the fin...
