Liquids generally have a lower density than solids. But you must have observed that ice floats on water. Find out why.
Density of ice is less than the density of water. The low density of ice can be attributed to the small pores it has which allows it to trap air hence ice floats on water.
Name A, B, C, D, E and F in the following diagram showing a change in its state.
What produces more severe burns, boiling water or steam?
Why is ice at 273K more effective in cooling than water at the same temperature?
Give two reasons to justify -
(a) Water at room temperature is a liquid.
(b) An iron almirah is a solid at room temperature.
What is the physical state of water at -
