The compression ratio of a certain diesel engine is 15 to 1. this means that in the compression stroke the air in the cylinder is compressed to 1/15 of its initial volume. if the initial pressure is 10^5 pa and the initial temperature is 300 k, find the final pressure and temperature after compression. air is mostly a mixture of diatomic oxygen and nitrogen, so treat it as an ideal gas with (gamma)=1.4 . take the process to be adiabatic and reversible.

Describe the function of the endomembrane system? what organelles are involved?

Describe uniform velocity and variable velocity in short

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
