A. a cook leaves a plastic spoon and a wooden spoon in a pot of hot water for the same length of time. the spoons have the same mass. if plastic has a higher specific heat capacity than wood has, which spoon will have a smaller change in temperature? write one or two sentences explaining your answer.

b. does a closed system obey the law of conservation of energy? write one or two sentences explaining your answer.

c. a hot piece of iron is placed into a container of water. describe two ways in which heat is transferred in this system.

d. if 0.25 kg of iron at 100°c is added to 1.00 kg of water at 24.0°c, what is the final temperature of the system? show your work.

e. to calculate the final temperature of the mixture, you had to assume that energy would not flow from the iron and water to the container. what type of system does this describe? explain your answer.

f. if heat could flow to the container, how would the final temperature be affected?

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
