A physical Change, such as a state changing or dissolving, does not create a new substance, but a chemical change does.In a chemical reaction the atoms and molecules that interact with each other are called reactants.In a chemical change reaction the atoms and molecules produced by the reaction are called products.only the atoms present in the reactants can end up in the products. No new atoms are created and no atoms are destroyed. Reactants contact each other, bonds between atoms in the reactants are broken,and atoms rearrange and form new bonds to make new products.

If the freezing point of a soda is – 4.5 ºC and you leave it in your car overnight when the temperature dips to 25 ºF, will the
Sveta_85 [38]

Explanation:

We leave a soda in the car overnight and the temperature dips to 25 °F. To see if it will freeze we have to convert the °F to °C.

T(°C) = ( T(°F) - 32 ) *5/9

T(°C) = (25 - 32) *5/9

T(°C) = -3.9 °C

Since -3.9 °C is a temperature greater than the freezing point (-4.5 °C) the soda won't freeze.

Answer: The soda won't freeze.
