Certain quantity of water cools from 70°C in the first 5 min and to 5

1.	Certain quantity of water cools from 70°C in the first 5 min and to 54°C in the next 5 min.the temperature of the surrondings is
Answer» ACCORDING to Newton's law of COOLING, RATE of cooling is directly proportional to the TEMPERATURE DIFFERENCE between the body and its surroundings. where θ₀ is the temperature of the surroundings. then θ₁ = 70°C and θ₂ = 60°C and t = 5 minutes. then θ₁ = 60°C and θ₂ = 54°C and t = 5 minutes
