Not awfully; it freezes at a relatively warm temperature and (unusually) it's density doesn't change in a linear way with temperature; if you cool water down, it reaches it's smallest volume at 4 degrees C, then the volume starts getting bigger again - so there are densities of water that can represent two temperatures.

That depends on how hot the water is in the cup. Use the thermometer to measure it and see.
You can use a food thermometer or a candy thermometer for measuring the temperature of boiling water. Make sure the thermometer is heat-resistant and can handle high temperatures. Insert the thermometer into the water without touching the bottom of the pot for an accurate reading.
Use a thermometer. =====================
You can measure the temperature of water using a thermometer. Insert the thermometer into the water and wait a few seconds for the reading to stabilize. The temperature displayed on the thermometer is the temperature of the water.

You can measure the temperature of water using a thermometer specifically designed for use in liquids. Place the thermometer in the water and wait for it to stabilize to get an accurate measurement. Submerge the thermometer deep enough to get an accurate reading.
A thermometer is commonly used to measure the temperature of water. Digital thermometers with a waterproof design are ideal for measuring water temperature accurately. Alternatively, a cooking thermometer or a probe thermometer can also be used for this purpose.
No.
No, it is not recommended to use a baby thermometer to test the temperature of water. Baby thermometers are specifically designed to measure human body temperature and may not provide accurate results for testing water temperature. It's best to use a thermometer specifically designed for measuring water temperature.
