Atemperature of a 50 kg block increases by 15°c when 337,500 j of thermal energy are added to the block. (chapter 5 – pages 141-142)
a. what is the specific heat of the object? show the appropriate equation from your book and show your work with units.
b. what is the block made of? use the chart on page 141.
c. is this block a good material for insulators or conductors?

Which of the following best describes the circuit shown below?

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.

Which model displays the change in a gas when the temperature of the gaseous system decreases?
