False
The faster the atoms/molecules move, the lower the temperature.
False
Heating a substance means that energy is transferred to the substance; energy is gained.
True
Learn about the transfer of energy through heating and cooling, and understand how it affects the speed of atoms and molecules, leading to changes in temperature. Explore the relationship between energy transfer and temperature measurement.
