physical changeWhen you first apply heat to a solid substance like butter, it melts into a liquid. This is a physical change. You can prove that this is a physical change because if you put the melted butter back in the fridge, it changes back to solid butter.
butter being melted on warm toast is also another physical change, the reason for that is because you still have butter it hasnt changed in terms of its properties, the onlything we did is melted it. the reason why it is a chemical change is because once you toast it you can not get it back to its original form.
Toasting bread is a chemical change. Adding heat to the bread cooks it, changing it on a molecular level.
When the butter is heated, the molecules begin to move and are able to slide past each other and become a liquid. When the liquid butter is cooled, the molecules slow down and reconnect to become a solid again.
Toast is a thousand times better than bread, and that is just a fact. It's a chemical reaction between the amino acids and sugar in bread when it's cooked, a form of non-enzymatic browning. This produces new odour and flavour producing molecules, meaning toast has an entirely different flavour to bread.
Toast is bread that has been browned by radiant heat. The browning is the result of a Maillard reaction, altering the flavor of the bread and making it firmer so that it is easier to spread toppings on it. Toast is a common breakfast food.
To make butter, the cream is agitated (stirred up) so that the fat molecules get shaken out of position and clump together. Eventually, after enough agitation, the fat molecules clump so much that butter forms.
Physical changes: Cutting vegetables and melting butter. Chemical changes: Rotting food, fermenting, charcoal burning in a grill, and plant decaying.
The explosion of fireworks is an example of chemical change. During a chemical change, substances are changed into different substances. Another words, the composition of the substance changes.

Whether you're cooking meat, toasting bread or roasting coffee, you're performing a particular chemical reaction – the Maillard reaction. This process, named for the French chemist who studied it, is the reaction between amino acids and reducing sugars in the presence of heat.
Explain that the butter is made up of molecules of fat. When the butter is solid, the molecules are close together and do not move past each other. When the butter is heated, the molecules begin to move and are able to slide past each other and become a liquid.
If you try to insert the duplicate key, it will replace the element of the corresponding key. HashMap is similar to HashTable, but it is unsynchronized. It allows to store the null keys as well, but there should be only one null key object and there can be any number of null values.
Neither Wishing you a happy weekend nor Wish you a happy weekend would be used in normal conversation. As others have noted, spoken parting platitudes at the end of a week are normally started with have, such as: Have a good weekend. Have a nice weekend.
