It depends on what type of car you are working on. all cares have different temperature thermostats. A very common temperature is 195 degrees
20 degrees Fahrenheit above the start to open temperature.
The thermostat's main job is to allow the engine to heat up quickly, and then to keep the engine at a constant temperature. It does this by regulating the amount of water that goes through the radiator. At low temperatures, the outlet to the radiator is completely blocked -- all of the coolant is recirculated back through the engine. Once the temperature of the coolant rises to between 180 and 195 F the thermostat starts to open, allowing fluid to flow through the radiator. By the time the coolant reaches 200 to 218 F, the thermostat is open all the way. It preforms this feat because there is wax inside the thermostat that melts at a preset temperature. If the thermostat is rated at 190 degrees F that is when it opens. That is it's temperature rating.
This is school work. You need to open the book to find the answer.
As with any thermostat it is based on where the set point is on the temperature scale. On hot water tanks the thermostat opens the element circuit when the set point temperature is reached. For example the set point should be around 135 degrees F. When cold water enters the tank, the thermostat closes due to sensing a temperature lower than the set point is set at. When the water heats up to 135 degrees the thermostat open because the set point is reached.To test the thermostat shut the power off at the distribution panel for the hot water tank. To do this test the water in the tank should be up to temperature. Remove the wires from the thermostat that is to be tested. Make a diagram of how the wires were connected. Using a continuity tester (ohm meter works fine) place the leads across the terminals where the wires were connected. If there is no reading then the set point is satisfied and the circuit is open. Leaving the tester leads on the terminals, with a screw driver raise the set point to a higher value. The meter should now show continuity between the terminals. Turn the set point down and the terminal reading should open. If this is happening then that thermostat is operating fine. Reposition the thermostat to the original set point. If you are working on the top thermostat now do the same to the bottom thermostat to see if it is working also.See related link below.

discovery 2 td5 thermostat starts opening at 82 deg c and is fully open at 96
20 degrees Fahrenheit above the start to open temperature.
should be fully open by 85 deg C
The thermostat controls operating temperature. This occurs at a preset temperature (typically 195 degrees F. or so), which is usually stamped on the thermostat itself. The thermostat should be fully open about 20 degrees F. above the rated temperature. So your operating temperature is about right. If you have doubts, just replace the thermostat with a new one of the correct temp.
A cooling thermostat only will be normally open, closing on the rise of temperature. A Heat only thermostat will be a normally open, close on the fall of temperature.
195 degrees Fahrenheit.
on the vr6 engine the factory thermostat is 180 but the engine should not get over 210 at 180 the thermostat starts to open and is fully open at 195
Is vehicle actually overheating? Could be a bad temperature sending unit or gauge Check temperature with a thermometer If thermostat does not open vehicle will overheat
Thermostats range in temperature from 175-205 degrees. Choose a 195 degree thermostat and you'll be fine.
Remove thermostat and place into a container of boiling water, watch to see if thermostat opens fully, allow to cool and watch to see that thermostat closes fully. Sometimes the temperature senitivity fails and will not open. Sometimes spring gets weak or broken and doesn't allow thermostat to close fully.
Depends on the type thermostat. On most vehicles it will open at 195 Degrees F.
