APCHEM-OIBKGZ

The temperature of a system is directly related to the kinetic energy of the system and any change in the kinetic energy.

Which of the following would BEST represent a system that has had the kinetic energy cut in half?

A

A system that starts at 50$^o$C and changes to -112$^o$C.

B

A system that starts at 50$^o$C and changes to 25$^o$C.

C

A system that starts at 0$^o$C and changes to -100$^o$C.

D

A system that starts at 100$^o$C and changes to 50$^o$C.
