1. Do not change the properties
a.physical change
b.chemical change
c.similarity

Answer:

(a) physical change

Explanation:

because phiysical chage is provide by physics

Answer is :

hysical changes are limited to changes that result in a difference in display without changing the composition. Some common changes (but not limited to) are:

Texture

Color

Temperature

Shape

Change of State (Boiling Point and Melting Point are significant factors in determining this change.)

Physical properties include many other aspects of a substance. The following are (but not limited to) physical properties.

Luster

Malleability

Ability to be drawn into a thin wire

Density

Viscosity

Solubility

Mass

Volume

Any change in these physical properties is referred to as a physical change. For further information, please refer to Properties of Matter.

Chemical changes, on the other hand, are quite different. A chemical change occurs when the substance's composition is changed. When bonds are broken and new ones are formed a chemical change occurs. The following are indicators of chemical changes:

Change in Temperature

Change in Color

Noticeable Odor (after reaction has begun)

Formation of a Precipitate

Formation of Bubbles

and chemical changes :  emical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust. A more general term for rusting and other similar processes is corrosion. Other terms that are commonly used in descriptions of chemical changes are burn, rot, explode, and ferment. Chemical properties are very useful as a way of identifying substances. However, unlike physical properties, chemical properties can only be observed as the substance is in the process of being changed into a different substance.

A chemical change is also called a chemical reaction. A chemical reaction is a process that occurs when one or more substances are changed into one or more new substances. Zinc  (Zn)  is a silver-gray element that can be ground into a powder. If zinc is mixed at room temperature with powdered sulfur  (S) , a bright yellow element, the result will simply be a mixture of zinc and sulfur. No chemical reaction occurs. However, if energy is provided to the mixture in the form of heat, the zinc will chemically react with the sulfur to form the compound zinc sulfide  (ZnS) . Pictured below are the substances involved in this reaction.

Read the poem.

The Song of Wandering Aengus

by William Butler Yeats

I went out to the hazel wood,
Because a fire was in my head,
And cut and peeled a hazel wand,
And hooked a berry to a thread;
And when white moths were on the wing,
And moth-like stars were flickering out,
I dropped the berry in a stream
And caught a little silver trout.

When I had laid it on the floor
I went to blow the fire a-flame,
But something rustled on the floor,
And someone called me by my name:
It had become a glimmering girl
With apple blossom in her hair
Who called me by my name and ran
And faded through the brightening air.

Though I am old with wandering
Through hollow lands and hilly lands,
I will find out where she has gone,
And kiss her lips and take her hands;
And walk among long dappled grass,
And pluck till time and times are done,
The silver apples of the moon,
The golden apples of the sun.

Read these lines from "The Song of Wandering Aengus."

Though I am old with wandering
Through hollow lands and hilly lands,
I will find out where she has gone,

How does Aengus's continued search for the girl affect the meaning in the poem?


It reflects his desire to recreate an odd experience he once had.


It shows he is trying to get in touch with the beauty and life he caught a glimpse of.


It reflects his obsession with a woman he once knew and cannot forget.


It suggests that Aengus misses the life he had when he was a young boy.

Which text structure has the author of this passage used?
Every year, nearly 1.2 million acres of land burn in wildfires. While lightning and other natural occurrences cause some of these fires, humans are to blame for 90 percent of wildfires. Campfires, equipment, and other human activities can ignite fires that end up spreading due to dry leaves, needles, branches, and weather conditions. Wildfires can help the ecosystem when they are contained, but they can also damage an area, making it difficult for the land to heal on its own and increasing erosion and landslides.
