1. Consider the following statements,
1] Interglaciation is the term used by geologists to refer to the alternating periods of warming and cooling in the earth’s past.
2] The cooler times are called the “glacial period” during which ice shelves from the Arctic slowly creep southward and spread across the earth.
3] Times when the earth is covered in these large ice sheets are known as glacial periods (or ice ages).When the ice sheets are not spread, it is called an interglacial period.
Which of the above statements is/are correct?
When water is cooled, it gets converted into ice by a process called P. When ice is warmed, it gets reconverted into the water in a process called Q. Identify P and Q.
When water is cooled to ice, its entropy
