What is the order of the seasons?
The seasons begin with Spring, Summer, Fall (Autumn), and then finally Winter. This then becomes a cycle.
Cycle of seasons?
We have 4 different seasons the 1st one is Winter, Spring, Summer and Autumn.
Does the seasonal cycle occurs because Earth is closer to the sun in the summer than in the winter?
The Earth rotates on it's axis. In the summer, the Earth is tilted towards the sun. In the winter, the Earth is titled away from the sun. On the Earth, the northern regions (above the equator) have winter, while the southern regions (below the equator) have summer. Then, the opposite becomes true. The southern regions have winter, while the norther regions have summer. The distance nearer and farther from the sun makes no difference as far as the Earth's summer and winter is concerned.
Why do CO2 concentrations cycle throughout the year?
If you look at a globe, you will notice that the majority of the land area of the earth lies north of the equator. As a result, more vegetation exists on the earth when it is summer in the northern hemisphere than exists when it is summer in the southern hemisphere. More vegetation means that more CO2 can be sequestered. The annual CO2 cycle is the result. If you want a good visualization of this process: watch An Inconvenient Truth - it is all explained there It's a bit more than that, during winter plants release CO2, so during the summer more O2 is released and CO2 sequestered, and in the winter the process is reversed (O2 being used in the respiration by detrivores). Since, as has already been stated, most land mass is in the Northern Hemisphere there is not enough Southern summer growth to balance the CO2/ O2 and so the concentrations cycle.
Why are streets and highways damaged so much more in the winter months than the summer months?
When snow thaws, the water seeps into any cracks in the surface. Then when the road freezes again the expanding ice makes the cracks larger. Repeat the cycle a few times and you will have potholes.
Difference between rankine and brayton cycle?
Brayton cycle: It is open cycle. Rankine cycle: It's close cycle. Brayton cycle: Mostly used in gas turbine engine. Rankine cycle: Mostly used in power generation plant. Brayton cycle: Resemble less to Carnot cycle. Rankine cycle: Resemble is more to Carnot cycle.
What is the difference between the Carnot cycle and the Rankine Cycle?
carnot cycle is a very ideal cycle that isn't practical at all , 'cause we add and reject heat isothermally , a wet mixture enters the turbine so it'll cause pitting and erosion and a wet mixture enters the pump , and the pump can't deal with a 2 phases fluid rankine cycle is a practical cycle but with a very low efficiency so the main difference lies in the adding and rejecting of heat
How to increase a Thermal efficiency of rankine cycle?
-increase the temperature of the super heated steam -lowering the condensing pressure -increasing the boiler pressure (Reheating, regeneration...)
What is the advantage of rankine reheat cycle?
Among other advantages, this pervents the vapor from condensing during its expansion which can seriusly damage he turbine blades, and improves he efficiency of the cycle, as more of the heat flow into the cycle occurs at higher temperature.

What is rankin cycle?
The Rankine cycle is the fundamental thermodynamic underpinning of the Steam_engine. It is named after William_John_Macquorn_Rankine
What type of cycle used in steam turbine?
Rankine cycle is used in steam turbine
What will be the effect to the thermal efficiency to a simple Rankine cycle when the turbine work output decrease?
The efficiency will decrease.Remeber the formula for effiency for a cycle:What we want over what we pay for. So,ηT=WT/QAWhereWT = Work done by the turbineQA = Heat taken from the hot reservoir
When did the summer Olympics and winter Olympics divide?
The Summer Olympics and Winter Olympics were held in the same year every four years until 1992. The summer games continued on their four-year cycle, but the winter games were held again just two years later in 1994 before returning to a four-year cycle.
What are four major components of the Rankine cycle?
The four major components of the rankine cycle are as follows: 1. boiler 2. turbine 3. condenser 4. pump i.e. in short (B-T-C-P)
