Absolutely. Your A/C compressor takes a lot of engine power to run. You will probably notice your vehicle has less abillity to accellerate as well when the A/C is on.
Cars that have electronic fuel pumps, has to have at least 40 psi. This is true for all vehicles since the fuel injectors needs this much pressure to operate properly.
No. A catalytic converter is part of the exhuast system. This is true for all vehicles. If you have problems with you air conditioner you should have a mechanic inspect the components. Any repair will cost you at least $75USD but could cost over $500USD.
I would say manual because you can regulate your RPM's to what would be best for your vehicles fuel efficency.In the past a manual transmission equipped vehicle would always get better fuel mileage. But on cars built in the last 5 years that is not always true. There are some vehicles where the A/T equipped vehicle gets as good or better fuel mileage than a manual. Especially cars equipped with a CVT automatic transmission.
The faster you drive the lower your gas mileage. This is true especially over 65 mph. IMPROVEMENT:: This depends on the type of vehicle,the type of engine,and how that engine is set up to function.... In other vehicles given the weight,aerodynamics and engine set-up you can get more MPG traveling at 65mph than you can at 35mph..this is especially true with many diesel engines which are able to shut down the fuel flow to one or more cylnders in the engine because the engine does not need all 10 cylnders using up fuel to maintain the desired speed... In other vehicles the fuel flow is computer controled so there is very little difference seen in the MPG between speeds of 55-70mph..and like the diesel engines some gasoline models can shut down the fuel flow to their cylnders as well thereby reducing fuel use at speeds of 55mph and over,in essence your vehicles V8 engine then becomes a V6 and uses less fuel.. The old saying that "the slower you drive the more gas you save" is not always true in fact many vehicles will use more fuel traveling at 25 mph than at 55 mph this is proven by the sticker on the window of city and highway MPG. such as 18mpg city-29mpg hwy.
Well first of all it stops. However you may be more concerned about whether or not it will start when refilled with fuel. From my experience the fuel injection system is self priming and needs no further intervention once the gas tank is refilled. This may not be true of diesel powered vehicles of which I know very little.
Yes, conditioner will help moisturize and add shine to the hair.

More mass is converted to energy in a fusion reaction than in a chemical reaction, such as that found in a fuel cell. - APEX
The engine computer on some vehicles may store a fuel mileage estimate. The later model Dodge Rams with the Cummin's diesel store estimated gallons of fuel used and miles driven.
The ac unit is a tax on the engine to run. This is true with all vehicles. Having the ac on will make the engine work harder to run the ac compressor. This makes the engine run hotter.
Yes it even helps it more than water. But i only know this is true with bio infusion smoothing conditioner. SHAMPOO KILLS PLANTS ! be caredul not to put too much though.
