Because a negative feedback system "closes the loop" based on a temperature sensor in the tip of the iron. This makes the temperature of the iron nearly constant whether sitting idle on the stand or being used to solder a massive joint. Without this negative feedback the temperature of the open loop iron would rise significantly when sitting idle on the stand and fall significantly when being used to solder a massive joint.
if we set timimg for cooking rice then it is open loopbut thermostat in electric cooker can not give more temmp, than 100deg. so some microprocessor is controlling here .thus in this case it will act as closed loop system.
closed loop system
Sensitivity of a closed loop system for a change in the system gain is 1/(1+GH)
The closed loop control refers to a system whereby an input forcing function is usually determined in part by the system response.
A Closed loop system basically will have a feedback which enables the rectification of the error in the main process,whereas it is not possible in an open loop system
Yes it is
It is called closed because all the plasma and its contents are contained within the vessels.

if it is an automatic you cant yourself it is a closed system. if it is a manual i dont know.
Closed circulatory system or sometimes called cardiovascular system
Granville Woods received over 60 patents. His major inventions included an improved telephone transmitter, an electrical apparatus for transmitting messages, an induction telegraph system, a galvanic battery, an automatic What_did_granville_woods_inventcut-out for electric currents, an electric railway supply system, a regulator for electric motors, an egg incubator, and an automatic air brake.
Unfortunately, Mercedes designed their SLK automatic transmissions as closed systems, without means of adding or draining fluid. Ostensibly, as a closed system, there is no need. How do you add fluid if you've had to replace a rear axle?
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.
You can't it is a closed system and it needs to be done by a professional.
Amphibians have closed circulatory system Closed
