A student takes some water in a beaker and heats it over a flame to determine the boiling point of water. He keeps on taking temperature readings. He observed that the temperature of water :
keeps on increasing regularly.
keeps on increasing irregularly.
first increases slowly, then decreases rapidly and eventually becomes constant.
first increases gradually and then becomes constant.

Solid carbon dioxide
Liquid carbon dioxide
Liquid oxygen
Liquid hydrogen
Evaporation causes
Heating

The thermometer that should be used to determine the boiling point of water is:
maximum and minimum therometer
clinical thermometer
celsius thermometer
room thermometer
The inter atomic distance is too low in
While determining the boiling point of water, we should always use distilled water because :
impurities may break the thermometer.
impurities increase the boiling point of water.
impurities decrease the boiling point of water
impurities may stick to the thermometer making it difficult to read the temperature.
