When ice melts, its temperature

When ice melts, its temperature

When ice melts, its temperature

What is the melting temperature ( T_m ) of DNA ? A DNA molecule with more number of GC base pairs than AT base pairs, has higher T_m than the one with lesser number of GC base pairs than AT base pairs. Explain why?

Melting temperature for double stranded DNA is the temperature at which 50% of the double stranded molecules are converted into single stranded molecules. Which one of the following DNA will have the highest melting temperature ?

A hard substance melts at high temperature and is an insultor in both solid and in molten state, The solid is most likely to be a/an:

A piece of ice is floating in a beaker containing water when ice melts, the temperature falls from 20^@C to 4^C When ice melts, the temperature falls from 20^@C to 4^@C and the level of water :

If T_(B) and T_(s) are the temperatures of the body and the surroundings and T_(B) -T_(s) is of very high value, then the rate of cooling in natural convection is proportional to .

What is the value of rate constant at extremely high temperature (T=infinity) Is this rate constant feasible? Why?
