Thermal energy moves in a predictable pattern from warmer to cooler until all the substances
attain the same temperature. This
means thermal energy (heat) moves
____________________ (away from/ towards)
fire.
Thermal energy moves in a predictable pattern from warmer to cooler until all the substances
attain the same temperature. This
means thermal energy (heat) moves away
from fire.
