10+ NxtWave Interview Questions and Answers

Solvent extraction involves using a solvent to separate compounds, while distillation involves separating compounds based on their boiling points.

• Solvent extraction uses a solvent to dissolve the desired compound, which is then separated from the solvent. Distillation involves heating a mixture to separate compounds based on their boiling points.

• Solvent extraction is often used in the extraction of essential oils from plants, while distillation is commonly used in the purific...read more

Vaporization is the process of turning a liquid into a gas through heat, while evaporation is the process of a liquid turning into a gas at a temperature below its boiling point.

• Vaporization requires heat to change a liquid into a gas, while evaporation can occur at room temperature.

• Vaporization is a rapid process, such as boiling water to create steam, while evaporation is a slower process, like a puddle drying up.

• Vaporization is a phase change that occurs throughout the liq...read more

Solvent extraction is a method used to separate compounds based on their solubility in different solvents.

• Solvent extraction involves mixing a sample with a solvent that can selectively dissolve the desired compound.

• The mixture is then separated into layers, with the compound of interest being extracted into the solvent layer.

• Common examples include extracting caffeine from coffee beans using water or extracting essential oils from plants using steam distillation.

Heat transfer is the process of energy moving from a warmer object to a cooler object.

• Heat transfer can occur through conduction, convection, or radiation.

• Conduction is the transfer of heat through direct contact between objects, like a metal spoon heating up in a hot drink.

• Convection is the transfer of heat through the movement of fluids, like boiling water in a pot.

• Radiation is the transfer of heat through electromagnetic waves, like the warmth felt from the sun.

• Heat transf...read more

pH maintenance raw materials dissolve in water and leaching time depend on the specific material and conditions.

• The number of pH maintenance raw materials that dissolve in water varies depending on the specific materials being used.

• Leaching time can also vary based on factors such as temperature, pH level, and agitation.

• Examples of pH maintenance raw materials include limestone, dolomite, and hydrated lime.

Distillation is a process of separating components of a liquid mixture based on differences in boiling points.

• Distillation involves heating the liquid mixture to create vapor, then cooling the vapor to condense it back into liquid form.

• The components with lower boiling points will vaporize first and be collected, while the components with higher boiling points will remain in the liquid phase.

• Common examples of distillation include the production of alcoholic beverages like wh...read more

Evaporation is the process by which a liquid turns into a gas due to heat energy.

• Evaporation occurs when molecules at the surface of a liquid gain enough energy to escape into the air.

• It is a cooling process as it removes heat from the liquid.

• Examples include water evaporating from a puddle on a hot day or sweat evaporating from our skin.

• Evaporation is an important part of the water cycle.

The question is unclear and seems to be asking about the number of pH maintenance nickel crystals.

• It is unclear what 'ph mainten nickel crystal' refers to

• It is possible the interviewer made a mistake in phrasing the question

• Ask for clarification or provide an educated guess based on context

The question is unclear and lacks context. It seems to be asking about the percentage of nickel in a maintenance solid, but more information is needed for a precise answer.

• Request clarification on the type of maintenance solid being referred to (e.g. metal alloy, coating, etc.)

• Ask for the specific context in which the nickel percentage is relevant (e.g. for corrosion resistance, strength, etc.)

• Provide examples of different nickel percentages in common maintenance solids for c...read more

The question is unclear and seems to be asking for the number of maintenance nickel GPL, which is not a standard term.

• It is unclear what 'mainten nickel GPL' refers to

• Ask for clarification or more context from the interviewer

• Provide examples of similar terms or concepts you are familiar with

The question is unclear and seems to be asking for a percentage of maintenance nickel.

• Ask for clarification on what 'mainten nickel %' refers to

• Provide examples of different interpretations of the question

• Offer to discuss the topic further to gain a better understanding

Reading drawings involves understanding symbols, dimensions, and tolerances to create accurate reports.

• Study the title block for important information like part number, revision, and scale

• Identify different views (top, front, side) and understand how they relate to the actual part

• Interpret symbols for features like holes, threads, and surface finishes

• Measure dimensions accurately using a ruler or calipers

• Note tolerances specified for each dimension to ensure part meets requir...read more

Least count of an instrument refers to the smallest change in the measured quantity that can be detected by the instrument.

• Least count is determined by the smallest division on the scale of the instrument.

• It is important to consider the least count when taking measurements to ensure accuracy.

• For example, a ruler with millimeter divisions has a least count of 1 mm.

• Another example is a digital caliper with a least count of 0.01 mm.
