The control knob thermostat is probably broken and all you have is on and off.
That will vary depending on the individual stove.
It is belived that the center of a stove burner con be over 600 degrees!
To cook on a two-burner gas stove start cooking on high heat over one burner and simultaneously turn on a second, empty, burner to a lower temperature.This will help you to cook different types of food and avoid them burning the food.
It is similar to Bunsen burner. It is used for high temperature burning.
Im not 100% sure but I have been told on high temperature if you are cooking on the stove
Sounds like you have a faulty switch in that burner knob.
To heat things up. Think of it as a single burner stove. It isn't a high heat like a stove but it is effective for heating soups and similar items. You can use frying pan on them, but it isn't usually an even heat.
All Matter
Aquastats are thermostats sensing the temperature of the water itself, and are used basically to stop and start the burner by controlling the electrical circuit. The temperature of the water is held within preset limits by the aquastats. As the temperature of the water drops to the low setting, the aquastat closes a contact and starts the burner. When the temperature reaches the high setting, the aquastat opens the contact and stops the burner. There is usually a high limit setting which will open the contact, if it should fail to open on the automatic HI/LO control. This feature can be contained within the same instrument or it might be a separate unit. What temperature should the aquastat be set at for the boiler?
a low temperature will freeze the substance, a high temperature will melt or turn the substance into vapor
The actual "cooking temperature" will depend on the cooking pot or pan you are using, and the efficiency of that pot or pan at conducting heat from the burner to the food you are actually cooking (rather than radiating it out into the kitchen). So, if the actual cooking temperature is of vital importance to you, then it is best to use a thermometer to check the food temperature, rather than the burner temperatures.
the temperature does not matter because there is no gravity
