The formula below, Newton's law of cooling, allows us to calculate the temperature of an object as it cools. T= R+ (To- R)e-kt T= temperature of the object after { minutes To = initial temperature R = temperature of the surroundings k = cooling rate (depends on the object and conditions) Suppose the temperature in Denver, Colorado was 55'F when a 5F arctic cold front moved over the state. Using k= 0.012, how long would it take a puddle of water to freeze? (Recall that water freezes at 32 F.) O A. just over 51 minutes O B. just over 55 minutes O C. just over 61 minutes O D. just over 65 minutes I rights reserved
