the termometre gets warmer
The mercury level in a thermometer placed in a hot tub of water will rise as the temperature of the water increases. This is because the volume of liquid mercury expands with higher temperatures, causing it to climb up the measuring scale in the thermometer.
The question must be asked carefully. If the thermometer is in water ice and there is no liquid water, and there is one atmosphere of pressure, the thermometer can read anything from the freezing point of water and lower, depending on the range of the thermometer. If the thermometer is in a stable mix of water and ice, it will read the freezing point of water.
It heats up and the water keeps warm for a certain amount of time
A "classroom thermometer" is a thermometer assigned to be kept in a specific classroom.
Yes, rust happens to iron nail though it is kept in distilled water.
Not all water is cold, but if it is, that is because the H20 molicules are slowing. Most water for drinking is kept cold.
A thermometer should be immersed in the ice water mixture in order to accurately determine the melting point of ice. This ensures that the thermometer is in direct contact with the substance being measured and will provide a precise reading of when the ice starts to melt.
When putting thermometer in the mouth of a crying child is difficult.
Sodium catches fire at room temperature. So it is kept in bowl of cold water.
When thermometer is kept inside the mouth
it will turn to ice
Many piezoelectric crystals can be used in water with no issues.
