## How does the cars stability against sidewinds change with increased speed of the car?

As a driving instructor I know my students have more control at slower speeds than at higher speeds. This is true even for pulling to a curb and backing straight.If my student is at 3-5 mph, he will stay in a straight line more often than backing up between 5-10mph.The faster a vehicle is going t...

## What is the difference between open and closed system in thermodynamics?

A system which can exchange mass as well as matter with the surroundings is called anopen system.Example:- Heating of CaCo3 in an open bulb.A system which can exchange energy but not matter is called a closed system.Example:- Calcination of CaCo3 in a sealed bulb.

## Why does the interior of a car heats up on a sunny day?

Heat transfer into the car on a sunny day - when the car is in the sun at least - is primarily via radiative heat transfer. The rate of heat transfer is proportional to the difference in the fourth powers of the temperatures of the heat source and the heat sink. It also depends on the transmissiv...

## If you consider a gallon of gas as having 100 units of energy and 25 of those units are used to move the car what law of thermodynamics accounts for the other 75 units of energy?

The Second Law of Thermodynamics.
