Question

What do these two changes have in common? Chicken cooking in an oven, making jam

A) Heat involved
B) Use of fruits
C) Both are chemical processes
D) Unrelated

Answer 1

Both chicken cooking in an oven and making jam involve the use of heat to bring about chemical changes.

Step-by-step explanation:

Both chicken cooking in an oven and making jam have the common factor of heat being involved. In both processes, heat is used to bring about changes in the substances being cooked. This is an example of a chemical change because the heat causes the substances to undergo reactions and form new substances.

Answer 2

Both chicken cooking in an oven and making jam involve heat and are chemical processes where new substances are formed due to the application of heat.

The correct option is A.

Step-by-step explanation:

The two changes mentioned in the question, chicken cooking in an oven and making jam, have the commonality that both processes involve heat.

When chicken is cooked, it undergoes various chemical reactions due to the application of heat, including the Maillard reaction, which browns the meat and adds flavor.

Similarly, making jam involves heating fruits and sugar together, which results in chemical reactions that thicken the mixture and change the texture and flavor of the fruits.

Both are chemical processes (option C) because they involve chemical reactions that result in the formation of new substances, and both processes are typically exothermic, as heat is released.

Unlike physical changes such as ice melting or paper being torn, which are changes in state or form without changing chemical composition, cooking meat and making jam transform the chemical structure of the ingredients.

The correct option is A.
