1. From now until 2050, the human population is expected to grow bigger, more slowly, older, and more urban. Of these four factors, which do you think will have the biggest effect on the climate or environment?

2. In the U.S., more and more people are living alone in their own homes and buying their own cars instead of living with family or carpooling. How can materialism and capitalism impact climate or environment?

3. The author proposes three lines of action to reduce both poverty and global greenhouse gas emissions: universal secondary education, voluntary contraception, and maternal health services, and smarter urban design and construction. Of these three, which do you think will have the greatest impact and why? Alternatively, suggest a different line of action and explain why you chose that.

4. Demographic factors (household size, city size, population density), institutional and economic factors (availability of public transport at reasonable cost/convenience), and a host of behavioral factors (propensity to walk, bike, carpool, or drive solo to work) can influence a person’s carbon footprint. Think about your personal carbon footprint. What do you think is your number one contributing factor to CO₂emissions? What is one way that you think you could reasonably reduce your carbon footprint?

The Racing Extinction Documentary discusses the 6th Extinction. What is mass extinction? How many have occurred in the past? What is the 6th Extinction and how does it compare to previous extinctions? What are you doing to drive the 6th Extinction? What could you do to stop it?

An orifice meter is used to measure flow rate of liquid in pipe shows a pressure difference of ' x ' m of water column when the flow rate is Q If flow rate is doubled then what is delta P?

A Rankine power cycle with reheat uses water as the working fluid. The inlet conditions of the
first stage turbine are 14MPa and 600oC. All the turbines are known to have isentropic
efficiency of 85%, however the pump is assumed as an isentropic pump. If the maximum
temperature is kept at 600oC and the condenser pressure is 6 kPa, by constructing a suitable
plot, show that having more than 2 reheat stages is not practical. (Hint: Take at least three
reheat pressures between 2 to 12 MPa)
Note: You may construct the plot on Microsoft Excel or manually on a graph paper. However,
all the calculations involved must be performed manually, in details and must be shown clearly.

Explain how diversity issues such as race, gender, age, religious affiliation and culture impact the client population (human trafficking)

Identify and explain the suitable reactor for homogeneous and heterogeneous reaction?

What is the most up-to-date information on hydrogen fuel cell use in automobiles in the United States? How many hydrogen fueling stations are there and where are they?

Describe and give an example of four (4) other factors besides natural selection that could lead to evolution (changes in allele frequency at the population level).

In a process to make jelly, the macerated fruit, which has 14% by weight of soluble solids, is mixed with sugar (1.22 Kg Sugar / 1.00 Kg fruit) and pectin (0.0025 Kg pectin / 1.00 kg fruit). Consider sugar and pectin as soluble solids. The resulting mixture is passed to an evaporator to produce a jelly with 67% by weight of soluble solid. Calculate, for a feed of 1000 Kg / h of macerated fruit, the Kg / h of mixture obtained, the Kg / h of evaporated water and the Kg / h of jelly produced.

Earth's climate system includes not only the Sun but also: land surfaces and albedo, water in its three phases, oceans covering much of the planet, and the atmosphere. Explain how each is involved in the climate system.

5. How do we know that the fossil fuel burning was done by humans?

6. Besides greenhouse gases, list three other factors that could conceivably account for a warming atmosphere.

Why is it relevant to explore the question of whether Africans came to the western hemisphere before Columbus?

Compute the ideal work required for the mixing of pure oxygen and pure nitrogen to produce air (21 mol % oxygen and 79 mol % nitrogen) at 25 °C and 1 bar in a steady-flow process if T _surrounding= 500 K. Assume that this process is an isentropic process and pure oxygen, nitrogen, and the air is an ideal gas. (8 points)
