Ihave a special thermos that has a vacuum chamber between my hot soup and its outside wall. because my soup is isolated from its surrounding by a vacuum,

a. my soup will stay warm forever because thermal energy cannot pass through a vacuum.
b. my soup will cool down because of conduction.
c. my soup will cool down because of radiation.
d. my soup will cool down because of convection. e. both b and d.

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.
