In my labs we use hot plates with a 0-10 temperature knob. The hot plates don't have a temperature monitor, so i have no idea how hot each number can increase it or how hot it is at the time. Sometimes i have labs where i have to heat something to more specific temperatures or else the reaction will change or it will boil over. My only option right now is to use a thermometer which isn't always practical, and still its easy to mess up.
Is there a general rule with hot plates and the heat knob numbers? I know there might be factors like, room temperature. But I'm not doing anything that requires super precision, so i only really need a decent estimate. The only thing i know is the temperatures are 25°C at "1" and 550°C at "10"

Only thing i could think of is heating water and checking the temperature before heating anything important. But i won't have enough time for that. And my professor might say things like "watch it and don't let it boil too violently", but i just feel like there's just too much of a chance of messing up.
