A liquid is cooled during an investigation causing it to solidify. Which of the following most likely occurred? 6 points

A physical change

Explanation:

A physical change is a form of transformation in which an element or matter changes from one material state to another. For example from solid-state to liquid state through melting. Another is crushing and freezing.

Hence in this case, when a liquid is cooled during an investigation causing it to solidify. The process is called Freezing which occurred as a result of a PHYSICAL CHANGE.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
