How does heat energy affect the movement of water molecules?
Leo AbeytaFaster movement
Heat energy transforms in to kinetic energy in water molecules, thus water molecules vibrate more/move faster (in a sense)

Isabella AlvarezHeat energy increases the kinetic energy of water molecules, causing them to move faster and farther apart from one another. This results in an increase in the volume of water and a decrease in its density.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- A gas expands in volume from 35.6 mL to 70.6 mL at constant temperature. What is the work done (in joules) if the gas expands against a constant pressure of 3.2 atm?
- If the burning of the fuel in a potato cannon performs 855 J of work on the potato and produces 1422 J of heat, what is #DeltaE# for the burning of the fuel?
- One #"mol"# of an ideal gas, initially at #"300 K"#, is cooled at constant #"V"# so that #"P"_f# is #1/4 "P"_i#. Then the gas expands at constant #"P"# until it reaches #"T"_i# again. What is the work #w# done on the gas?
- A #6 L# container holds #5 # mol and #6 # mol of gasses A and B, respectively. Groups of three of molecules of gas B bind to two molecules of gas A and the reaction changes the temperature from #480^oK# to #270^oK#. How much does the pressure change?
