The purpose of a car engine is to transform the chemical energy of gasoline into kinetic energy of the car in motion. Gasoline
is burned in the engine to create that movement. However, gasoline engines are typically only about 20% efficient. What happens to the rest of the energy released from the burning gasoline?
most of the gasoline's energy is released as heat energy rather than kinetic energy on the pistons. this is why a car engine must constantly be cooled by the water to air heat exchanger we call a radiator
Histidine is a compound that is normally used for the generation of protein. Three amino acids commonly have basic side chain when the pH is neutral. The conjugate acid in histidine has a pKa of approximately 6. Based on the description of the experimental analysis provided in the statement, the right option is option c.
I believe it’s because they are trying to find other things that won’t pollute the environment as much, and they are also doing this because we are trying to reduce green house gas. Sorry if i’m wrong :(
