A cooling curve is plotted between the temperature of a hot body and time. Which of the following is not true for the cooling curve?

While drawing cooling curve between the temperature of hot water and time we should stir the water uniformly, this has been done to ensure that

A hot liquid is kept in a bog room. Accoding to Newton's law of cooling rate of cooling liquid (represented as y) is plotted against its temperature T . Which of the following curves may represent the plot?

A hot liquid is kept in a big room. According to Newton's law of cooling rate of cooling liquid (represented as y) is plotted against its temperature T . Which of the following curves may represent the plot?

Which of the following graphs represents rate of cooling of hot water?

According to Newton's law, rate of cooling is proportional to the difference between the temperature of the body and the temperature of the air. If the temperature of the air is 20^(@)C and body cools for 20 min from 100^(@)C to 60^(@)C then the time it will take for it temperature to drop to 30^(@) is
