The correct graph between the temperature of a hot body kept in cooler surrounding and time is (Assume newton's law of cooling)

Graph of rate of cooling against time is (assume Newton's law of cooling)

Graph of rate of cooling against time is (assume Newton's law of cooling)

A body cools in 7 minutes from 60^(@)C to 40^(@)C . What will be its temperature after the next 7 minutes? The temperature of the surrounding is 10^(@)C . Assume that Newton's law of cooling holds good throughout the process.

The temperature of a body in a a room is 80^@ F After five minutes the temperature of the body becomes 60^@ F . After another 5 minutes the temperature becomes 50^@ F . What is the temperature of surrounding ? ( Newton's law of cooling )

The temperature of a body falls from 52^(@)C to 36^(@)C in 10 minutes when placed in a surrounding of constant temperature 20^(@)C . What will be the temperature of the body after another 10min . (Use Newton's law of cooling)

A body cools from 70^(@)C to 50^(@)C in 6 minutes when the temperature of the surrounding is 30^(@)C . What will be the temperature of the body after further 12 minutes if coolilng proseeds ac cording to Newton's law of cooling ?

The temperature of a body in a a room is 80^@ C After five minutes the temperature of the body becomes 64^@ C and 10 minutes the temperature becomes 52^@ C . What is the temperature of surrounding ? ( Newton's law of cooling )

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?

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?

A body cools in 7 minute from 60^@C to 40^@C . What time does it take to cool from 40^@C to 28^@C if the surrounding temperature is 10^@C ? [Assume that Newton's law of cooling is valid.]
