• a.  At warm temperatures, molecules move around more
• b.  At warm temperatures, molecules grow in size

• c.  At warm temperatures, molecules exchange electrons more easily

• d.  At warm temperatures, molecules combine with each other more easily

Thermal Energy depends upon the energy of the particles as well as the number of particles.

Which would have more thermal energy, a small cube of Ice at zero Celsius or a large cube of ice at zero Celsius?

• The large ice cube because it has more particles than the small ice cube

• The small cube of ice because it will melt faster than the large ice cube

• Neither, they are cold so they do not have thermal energy

• both have the same thermal energy because they are both at zero Celsius.
