Gasoline contracts in cold weather because of the decrease in temperature, causing the molecules in the liquid to move closer together and reducing its volume. This contraction is due to the laws of thermodynamics, where substances generally contract when cooled and expand when heated.

How could the composition of gasoline be altered to increase the ease starting of a car in cold weather?

Increasing the proportion of lighter hydrocarbons such as butane or pentane in the gasoline mixture would make it easier for the engine to start in cold weather. These lighter hydrocarbons evaporate more easily, creating a more combustible mixture that ignites more readily in cold temperatures. However, it is important to note that altering the gasoline composition too much can affect engine performance and emissions.


How can your penis shrink?

Yes it can. It can shrink a small amount with age, and it will temporarily shrink when the body is cold. The whole reason the penis and the testicles are located outside the body is that the sperm cells need to maintain a certain temperature. When the weather is cold, or you're in cold water, the penis and scrotum will shrink up to be closer to the body, where it is warmer. The cremaster muscles will also pull the testes further into the body.
