Q & A
What is the main objective of the first experiment titled 'Properties and Changes of Matter'?
-The main objectives of the experiment are to enable students to understand the physical and chemical properties and changes, to identify the physical and chemical properties of a substance, to identify physical changes in a substance, and to identify characteristics observed from chemical changes in a substance.
What are the types of changes that all matter undergoes?
-All matter undergoes two types of changes: one that results in the formation of new substances and another that does not.
How can we benefit from understanding the changes that matter undergoes?
-Understanding the changes that matter undergoes allows us to utilize beneficial changes more effectively and prevent or slow down detrimental changes.
What materials are required for the experiment according to the script?
-The materials required for the experiment include styroform and acetone.
What are the different types of containers used in the experiment?
-The experiment uses four different types of containers: aluminum, glass, plastic, and a measuring glass.
How much acetone is used in each container during the experiment?
-Each container is filled with 50 ml of acetone.
What is the procedure for testing the styroform in the experiment?
-The procedure involves placing a piece of styroform into a chemistry glass containing 50 ml of acetone.
What is the purpose of observing changes in the containers during the experiment?
-Observing changes in the containers helps to identify the physical and chemical properties and changes of the substances involved.
Why is it important to understand the physical and chemical properties of a substance?
-Understanding the physical and chemical properties of a substance is important for predicting how it will react under different conditions and for safely handling and using it.
What is the significance of distinguishing between physical and chemical changes?
-Distinguishing between physical and chemical changes is significant because physical changes are reversible and do not alter the chemical identity of a substance, while chemical changes result in the formation of new substances and are usually irreversible.
How can the experiment help in identifying the characteristics of chemical changes?
-The experiment can help in identifying the characteristics of chemical changes by observing the formation of new substances, changes in color, production of gas, or changes in the state of matter.

Highlights
Welcome to the first trial titled 'Properties and Changes of Materials'.
The first objective is for students to understand the physical and chemical properties and changes.
The second objective is for students to identify the physical and chemical properties of a substance.
The third objective is for students to identify physical changes in a substance.
The fourth objective is for students to identify characteristics observed from chemical changes in a substance.
All materials undergo changes; some result in new substances, while others do not.
Understanding the changes that occur allows for beneficial changes to be utilized and harmful changes to be prevented or delayed.
The changes in materials depend on the physical and chemical properties each material possesses.
The first material required in this experiment is styrofoam, and the second is acetone.
The first tool used is an aluminum container, the second is a glass container, the third is a plastic container, and the fourth is a glass measuring cup.
The first procedure is to prepare a solution of acetone.
The second procedure is to prepare four containers with different materials that have been cleaned and dried.
The third procedure is to pour 50 ml of acetone into the aluminum, plastic, and glass containers, using a measuring cup.
For the styrofoam test, a piece of styrofoam is inserted into a chemistry glass containing 50 ml of acetone.
Observe the changes in each container.
This concludes the experiment on properties and changes of materials. It is hoped that it will be useful and understood. See you in the next experiment.

selamat datang dalam percobaan satu
berjudul sifat dan perubahan materi
Adapun yang menjadi tujuan dari
percobaan ini yang pertama mahasiswa
mampu memahami sifat dan perubahan
fisika dan kimia yang kedua mahasiswa
mampu mengidentifikasi sifat fisik dan
kimia suatu zat yang ketiga mahasiswa
mampu mengidentifikasi perubahan fisik
pada suatu zat yang keempat mahasiswa
mampu mengidentifikasi ciri-ciri yang
teramati dari perubahan kimia suatu
zat semua materi selalu mengalami
perubahan ada perubahan yang
menghasilkan zat yang baru ada pula
perubahan yang tidak menghasilkan zat
baru kita perlu memahami perubahan yang
terjadi sehingga perubahan-perubahan
yang menguntungkan dapat lebih
dimanfaatkan sedangkan
perubahan-perubahan yang merugikan dapat
dicegah atau diperlambat perubahan
materi yang terjadi tergantung sifat
fisik dan sifat kimia yang dimiliki
masing-masing materi atau
bahan bahan-bahan yang dibutuhkan dalam
percobaan ini yang pertama steroform dan
juga
aseton Adapun alat yang digunakan yang
pertama wadah aluminium wadah kaca wadah
plastik dan juga gelas ukur 50
mili prosedur percobaan yang pertama
siapkan larutan
aseton Yang Kedua siapkan empat wadah
dengan bahan yang berbeda-beda yang
telah dibersihkan dan dikeringkan yang
ketiga masukkan masing-masing 50 ml
aseton ke dalam wadah aluminium plastik
