How does the volume of water in an expansion thermometer change?
When the water cools down, the liquid will contract and the water level will go down. Since the volume change is directly related to the temperature in both cases, your thermometer can tell you the temperature change by measuring the volume change! The volume of liquid in an expansion thermometer depends on the temperature of the liquid.
How are the volume of two thermometers related?
If two thermometers start out at the same temperature and then one is put in a hot environment and one in a cold, their volumes will change. A scale on the side of a thermometer shows how volume is related to temperature. *The molecules in a liquid don’t all have the same amount of kinetic energy even when the liquid is at a specific temperature.
When to use a thermometer in hot weather?
Misplacement may lead to the effect @Barry pointed out, but in any case, many are calibratable, and the real uses for them are to indicate when you are approaching extremely hot or cold conditions (which could require a change in behaviour or fluids)
Why does the body feel hotter than the thermometer?
Perceived temperature, or the way we feel external heat, can be influenced by humidity, clothing and our level of hydration. With all this combined, we feel hotter than the reading on the thermometer.
Why does the temperature gauge go to high when you come to a stop?
Firstly, how high does the temperature gauge rise when you come to a stop? It is normal for this to occur, especially in warmer climates such as Arizona or Nevada. If it continues to rise into the red, then it is definitely a problem however. The next possibility has to do with air flow through the fins of the radiator.

When does the temperature rise in a Honda Accord?
I have a 92 Honda Accord. This just started happening, but after I start the car in the morning or after work and drive it for 15-20 minutes, everything is fine. After this period, when I come to a stop or put the car into park, the Temperature gauge begins rising until it gets to the “H”.
Why is the temperature in my house higher than the thermostat?
We get lots of concerned phone calls and emails. Nearly every one of them wants one question answered: Why is the temperature in my house higher than the temperature on my thermostat? In short, the answer is don’t panic! Your A/C is designed to keep your house around 75 degrees on days that are 95 degrees and up.
