It is predicted by the meteorologists that global warming will result in the flooding of oceans due to the melting of ice caps on the earth . During the melting process what changes will occur to its internal energy.

It is predicted by the meteorologists that global warming will result in the flooding of oceans due to the melting of ice caps on the earth. Name the thermodynamic process involved in the melting of ice.

During the past century, the temperature of the earth has increased by 0.6% most of it during the last few decades. Rise in temperature causes serious changes in the environment, thus leading to increased melting of polar ice caps and other places like Himalayan snow caps. Suggest any two control measures that will reduce global warming.

a) In a process 701 J of heat is absorbed by a system and 394 J of work is done by the system. What is the change in internal energy for the process? b) What is free expansion? What is the work done during free expansion of an ideal gas?

For the melting of ice at '25^circ C' : 'H_2 O(s) rarr H_2 O(l)' the enthalpy of fusion is '6.97 kJmol^(-1)', and entropy of fusion is '25.4 J mol^(-1) K^(-1)'. Calculate the free energy change and predict whether melting of ice is spontaneous or not at this temperature.

United Nations framework convention on climate change, an international treaty sighned by 194 countries to cooperatively discuss global climate change and its impact. As a science student, explain. What is global warming?

The enthalpy change for the evaporation of a liquid at its boiling point 127^(@)C is + 40.32 k J mol^(-1) . What is the volume of internal energy change for the above process at 127^(@)C ? (R = 8.3 JK^(-1) mol^(-1))
