The EU is a political and economic union of 28 countries, which developed an internal single market through a standardised system of laws. Politically, these 28 countries are linked by the European Parliament, the European Commission, the Council of Europe and the European Council (the last two have similar names, but they have different functionalities). Economically, by the ECB - the European Central Bank. Monetarily, by the Eurozone and the currency EURO, which is present in 19/28 countries. Also, there's a Schengen area, where passports are abolished and you can travel freely, BUT not all the countries that are in the EU, are in Schengen area (ex. Romania, Bulgaria); and vice-versa: Norway is not in the EU, but is part of the Schengen area.
I hope I helped, I used to have a "map" of interactions of all these countries in different unions/institutions, but cannot find it. If you need one to help you understand the EU better, tell me and I'll intensively look for it!
Update: here's the map.
Chemical change would have to involve a component that is a chemical for instance antifreeze if they used antifreeze to freeze the water then it would be considered a chemical reaction but since the water was, according to the information you gave me, froze by temperature than it is physical. You could also compare it to your body's temperature change if it changes from being under the sun its probably because of a physical character like natural sunlight<span />
Answer:
The high-involvement hierarchy
Explanation:
Roderick wants to evaluate several products before deciding which one to buy for his daughter, because he wants to buy the product that has an affective value, as there are several products that perform the same activities.
For this reason, we can conclude that Roderick's actions reflect the concept of high involvement hierarchy, which is a type of pre-purchase evaluation, where a product is chosen based on the attributes and the degree of affective involvement that the product passes to the client. This usually occurs with multiple products that perform the same function.
