2. Take a bowl of ice, put it out in direct sunshine and note its temperature after every 05 minutes. What type of change in its temperature, do you observe? How much time will it take to melt completely? Now put the same water on a stove and note down its temperature after every 30 seconds. What type of change in its temperature, do you observe now? How much time will it take to boil? Explain your observations with the help of time and temperature chart. (Perform this experiment on a sunny day) (6 marks)

Perimeter? wheres the answers

The formula is (nh4)2co3
