Newton's law of cooling states \frac{d \theta}{d t}=-k(\theta-T) where theta is the temperature at time t, T is the constant surrounding temperature and k is a constant. If a mass

with initial temperature, O0, of 300 K is placed in a surroundings of 316 K, and k is 0.02 s1, what is its temperature after 4.3 minutes? Give your answer to 4 significant figures and remember to use units.
