6. Read the text about thermodynamics and unscramble the letters in the brackets to
find the correct word. Translate the text.
Thermodynamics is the study of the relationship between
h______(tahe) and work. In
other words, thermodynamics looks at how we can put
e__________(renyge) into a system
(whether it is a machine or a molecule) and make it do work. Alternatively, we might be able
to do some work on a system and make it produce energy (like spinning the turbines in a
power station to produce
e____________(trielectyci)).

In
c___________(micehryts), we sometimes speak more broadly
about "energetics" of reactions (rather than thermodynamics), because
energy given off during a
r_________(tirecano) may simply be lost to
the surroundings without doing useful work. Nevertheless, the ideas are
the same: energy can be added to a set of molecules in order to produce
a reaction, or a reaction can occur between a set of molecules in order to
r________(esreale) energy.
