Physical properties of ice, water and steam are very different. What is the chemical composition of water in all the three states ?
How will you justify that ice, water and steam are not different substances but different states of the same substance ?
One end of a uniform rod of length 10m is placed in boiling water while its other end is placed in melting ice. A point P on the rod is maintained at a constant temperature of 450^@C . The mass of steam produced per second is equal to the mass of ice melted per second. If specific latent heat of steam is 7 times the specific latent heat of ice, the distance of P from the steam chamber must be___________(in m)
Water as ice has a cooling effect, whereas water as steam may cause severe burns. Explain these observations.
A heater melts 0^@C ice in a bucket completely into water in 6 minutes and then evaporates all that water into steam in 47 minutes 30 sec . If latent heat of fusion of ice is 80 cal//gram , latent heat of steam will be (specific heat of water is 1 cal//gam-^@C )
