In an arbitrary scale of temperature, water freezes at 40 °C and boils at 290 °C. The boiling point of liquid in this scale if it boils at 62 °C is (a) 9.8 °C
(b) 195 °C
(c) 68 °C
(d) 38 °C

Process should be shown

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
