- Explain the method for the preparation of 1 normal solution of hydrochloric acid.
- What is protein in Chemistry?
- Explain the third law of thermodynamics.
The third law states that 'As a system approaches absolute zero, the entropy of the system approaches a minimum value'. - What is entropy?
Entropy is a measure of disorderliness. It explains the system's closeness to equilibrium. - What is Gibbs free energy?
It is the available energy or the greatest amount of mechanical work done by a system at constant temperature and pressure. - At what temperature does water have maximum density?
At 4 deg C the density of water is 1000 kg/cu.m. - What is an isochoric process?
It is a thermodynamic process at constant volume. Also called isovolumetric process - What is a CSTR and what are its basic assumptions?
Continuous Stirred tank Reactor. Assumptions are steady state, constant density, constant temperature, one irreversible first-order reaction. - List the advantages and disadvantages of a PFR.
Advantages: Continuous operation, high conversion rate, less cost for operation. Disadvantages: temperature gradients, high maintenance cost. - Explain the functioning of a three-way catalytic converter.
Carbon monoxide oxidation, Nitrogen oxide reduction, uncombusted hydrocarbon oxidation. - Explain global warming from a common man's and an engineer's
perspective.
In a common man's perspective, the increase in world temperatures is global warming. In an engineer's perspective, it is the average temperature increase in the surface temperature of the earth, mainly due to increased concentration of greenhouse gases. The greenhouse gases capture the heat radiated by the earth, inside the atmosphere, enabling the increase in temperature. - What is carbon sequestration?
A technique for capturing carbon dioxide for a long term in order to reduce its effects on global warming. - What are the greenhouse gases in earth's atmosphere?
Water vapor, carbon dioxide, ozone, methane, nitrous oxide and CFC. - Define octane number.
It is the resistance to detonation of a fuel in a spark ignition engine compared to the isooctane-n-heptane mixture. - Explain the working of a spray condenser
A spray condenser is used for the condensation of humid water vapor by direct contact with water. The inlet water is at a temperature less than the dew point of air in the chamber. - How does a cyclone separator work?
It works as gas-solid separation equipment using vortex formation. - Define viscosity.
Viscosity is a measure of a fluid's resistance to shear stress. - What is critical radius of insulation?
The critical radius of insulation is the thickness of an insulation that does not affect the convection resistance. It is the ratio of the thermal conductivity of the insulator to the convection heat transfer coefficient. - What is a black body?
An ideal object that absorbs all electromagnetic radiations.
- Tell me about yourself... (Your answer should contain much more about your job skills than your personal life.) Talk about the growth of your career, what you learned from previous employment or even things like how your volunteer worked help you develop your organizational, time management and leadership skills.
- What are your strengths? (If you really enjoy new
challenges and tackle them in an organized manner, this would be a
useful strength in almost any situation.)
You can talk about your ability to find unique solutions to
problems. Be prepared with some concrete examples, since that may
be
the follow-up question.
- What are your weaknesses? (A "good" weakness might be
that you have trouble leaving the office behind when you go home in the
evenings.)
This is a very difficult question that is not asked often, but
it's one
you should prepare for anyway. If you talk about your temper,
your
tendency to gossip or the fact that you're lazy, you may as well
pack up
and go home right then. If you mention a weakness such as your
lack
of patience with people who don't do their share of the work, you
should
also mention that you keep this impatience to yourself and try
very hard
not to express it toward others.
- Do you have any questions about our company? (If you have
paid attention during the interview and if you have done your homework,
this would be a good time to ask for more details about some aspect of
the company's organizational structure or products. It would not be a
good time to ask about your first raise. You could also ask questions
about the community, their training program or
details about the work environment.)
- Where do you expect your career to be in 10 years? (Be
careful here. You do not want to give the impression that you're simply
using this company as a stepping stone to another career. Think of a
related managerial position within the company that would interest you.)
There is a story about a young accountant who was asked this
question by a
CPA firm during an interview. The young accountant replied that
he
saw himself as the comptroller of a large corporation. In other
words, "I'm just using your firm to teach me and then after you
spend
your resources training me, I will leave to go work for someone
else." Needless to say, he was not offered a position with the
CPA firm. They know that 75% of the people they hire will leave
within 10 years, but they do not want to hire someone who comes in
with
that plan.
- What skills do you have that would benefit our company?
(If your skills are not exactly those that the company may have
requested, you can point out the skills you have that would be valuable
to any company. Examples of these skills are: your ability to plan and
execute long-term projects, your ability to organize information into
usable data, your ability to research complicated
issues, or your ability to work well with a team.) If your skills
are not
perfect for this particular company, you can mention how quickly
you were
able to adapt and learn in other situations. Again, be prepared
with
specific examples in case you are asked to elaborate.
- Why did you leave your last job? (This is not an opening to speak badly of your former employer. There is almost always a way of wording the explanation so that you do not sound like a "problem employee" and your former employer does not sound like an undesirable company.) As unfair as it may seem, there is almost no time when you should say something bad about your former employer. You can talk about the lack of potential for upward mobility, the fact that your job responsibilities changed to the point that it no longer fit into your career plan, your need to move to be closer to your aging parents, the need to reduce travel time, your need for a more challenging job, or anything else that does not get into personalities or other conflicts. If you were fired for cause, you may want to be up front about it, explain the circumstances and accept responsibility for your actions. Practice your answers to this question with someone who has interview experience. However, don't lie. If you can't say anything positive about your former employer, don't say anything. It could come back to haunt you.
