In order to fnd the specifc heat c of an unknown substance, you place 75 g of the substance in a 30 g copper calorimeter that contains 65 g of water, all initially at 20 °C. You then add 100 g of water at 80 °C, and measure the fnal temperature of the system to be 49 °C. Assuming no heat is lost to the environment, what is c? [Answer: c = 2200 J/kg. K]

Consider an introductory thermodynamics class experiment used to demonstrate phase change phenomena. A beaker of water is heated, and its temperature measured over time to establish the temperature at which boiling occurs. The results, shown in the Figure below, are for three separate tests conducted on different days by different student groups using the same equipment and method. Why might the data from three seemingly identical tests show different results?

An accident at a nuclear power plant has left the surrounding area polluted with radioactive material that decays naturally. The initial amount of radioactive material present is 16 su (safe units), and 4 months later it is still 10 su. (a) Write a formula giving the amount A(t) of radioactive material (in su) remaining after t months. (b) What amount of radioactive material will remain after 8 months? (c) How long will it be until A = 1 su, so it is safe for people to return to the area?
The rate of infections with respect to time t (measured in days) within a population is seen to be rising exponentially according to the relation: I = e(k–1)t (Infections per day) This occurs over a period of 20 days from time t = [0, 20], where k = 1.4. a) What is the period of time t required for the initial infection rate I(t = 0) to double in number? State answer to within 3 decimal places.
