[True or False] 1 False [Statement] 
Heating an object always increases its temperature. False. Heat is a process of energy transfer that naturally occurs between objects with different temperatures. The heat flow transfers energy from the higher temperature object to the lower temperature object. Temperature is proportional to the average thermal kinetic energy of the molecules in a substance. Ice at zero degrees Celsius can absorb heat from warm surroundings and become water at zero degrees Celsius. Steam (water vapor) at 100 degrees Celsius can lose heat to cooler surroundings and become water at 100 degrees Celsius. In both these cases where there is a change of phase of a substance, energy absorbing or releasing processes occur that do not affect the molecular thermal motion. So the temperature of the ice/water/steam remains the same.
