Question

which of
the folloveng substance can
produce largest cooling
effect a ice at 0 degreec b water at 0 degree c (c) water at -1 degreec d cooling effect of all is same ​

Answer 1

Answer:

Ice at zero centigrade has greater cooling effect than water at 0^∘C .

Answer 2

Correct answer should be option number (c) since water at -1°C is simply ice at -1°C and for ice at -1°C firstly it would take energy from environment and go to ice at 0°C and then it would take extra energy to form water at 0°C so more the energy taken by the system more will be cooling effect so maximum energy taken by the system is in option number (c) so correct answer would be option number (c).
