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...

What will be the change in temp and pressure of air inside a car tire while moving?

The tire will most likely heat up in the summer due to the road being warm. As air heats up it expands and as air cools it condences.It all depends on the road conditions. So if its warmer outside or the pavement is warm the tire pressure will rise if it's cooler out it wont expand as much but it...

How much of the energy in gasoline or diesel fuel is converted to work in propelling the car and how much into heat released into the atmosphere?

Gasoline engines convert about 30 percent of the fuel's energy content into mechanical work, diesel engines about 45 percent. The rest is heat rejected in the radiator cooling or in the exhaust, or to heat the car interior in cold weather.
