The true statements about thermal energy from the options provided are:
B. Thermal energy flows from hot to cold.
C. Substances increase in temperature when their particles move faster.
D. Thermal energy transfers down a heated rod as molecules in the rod transfer kinetic energy from one molecule to the next.
Statement A is false because the ability of a material to transfer energy (conductivity) does not depend on temperature but rather on the material's properties. Metal generally conducts heat better than plastic, regardless of temperature.
