Question

True or False: The amount of heat absorbed or evolved is proportional to the masses of the reacting materials.

True   or   False:           Enthalpy is defined as the change in heat at constant pressure

True   or   False:          Heat always flows from the hotter system to the cooler system.

Were the reactions you performed exothermic or endothermic? Why?

Answer 1

True or False: The amount of heat absorbed or evolved is proportional to the masses of the reacting materials. It is typically due to the amount of moles, not mass, that the that reaction evolves

True   or   False:           Enthalpy is defined as the change in heat at constant pressure. This is the formal definition, it is considered in many aspects of chemical reactions i.e. heating, sensible heat, latent heat, ionizatin, etc..

True   or   False:          Heat always flows from the hotter system to the cooler system. In thermodynamics, the zeroth rule states that heat always goes from High temperature ( i.e. hot) to low temrpature (i.e. cool)
