Berikut yang termasuk besaran pokok.....
- A.
Volume
- B.
Panjang
- C.
Luas
- D.
Massa jenis
Correct Answer
B. PanjangExplanation
The given options are all physical quantities, but the question asks for the fundamental quantities. In physics, there are seven fundamental quantities, and length (panjang) is one of them. The other fundamental quantities are time, mass, electric current, temperature, amount of substance, and luminous intensity. These fundamental quantities are independent and cannot be derived from any other quantities. Therefore, length is considered a fundamental quantity.Rate this question:

Alat pengukur suhu adalah ....
- A.
Penggaris
- B.
Meteran
- C.
Termometer
- D.
Barometer
Correct Answer
C. TermometerExplanation
The correct answer is "Termometer" because a thermometer is a device used to measure temperature. It is specifically designed for this purpose and is commonly used in various fields such as weather forecasting, medical applications, and scientific research. A thermometer typically consists of a glass tube filled with a liquid (usually mercury or alcohol) that expands or contracts with changes in temperature, allowing for an accurate measurement to be taken.Rate this question:

Asam merubah lakmus biru menjadi warna ....
- A.
Tetap biru
- B.
Merah
- C.
Hijau
- D.
Putih
Correct Answer
B. MerahExplanation
When acid is added to blue litmus paper, it turns red. This is because blue litmus paper is used to test for acidity. When an acid is present, it reacts with the litmus paper and changes its color to red. Therefore, the correct answer is "Merah" which means red in Indonesian.Rate this question:

Berikut termasuk Indikator alami adalah ....
- A.
PH meter
- B.
Kertas lakmus
- C.
Bunga sepatu
- D.
Bunga Bangkai
Correct Answer
C. Bunga sepatuExplanation
Bunga sepatu termasuk indikator alami karena memiliki pigmen alami yang dapat mengubah warna air menjadi merah atau biru tergantung pada tingkat keasaman atau kebasaan air. Hal ini dapat digunakan sebagai indikator alami dalam percobaan kimia untuk menentukan pH larutan.Rate this question:

Zat tunggal yang tidak dapat diuraikan lagi menjadi zat lain yang lebih sederhana melalui reaksi kimia sederhana,merupak pengertian dari ...
- A.
Unsur
- B.
Senyawa
- C.
Atom
- D.
Ion
Correct Answer
A. UnsurExplanation
The correct answer is "Unsur". An unsur is a pure substance that cannot be broken down into simpler substances through chemical reactions. It is the fundamental building block of matter and is made up of only one type of atom. Unlike compounds, which are made up of two or more elements chemically combined, an unsur exists in its simplest form.Rate this question:

Berdasarkan wujudnya, zat dibedakan menjadi,kecuali
- A.
Zat gas
- B.
Zat keras
- C.
Zat padat
- D.
Zat cair
Correct Answer
B. Zat kerasExplanation
The given options are discussing different states of matter. They include gas, solid, and liquid. However, "zat keras" does not fit into any of these categories as it translates to "hard substance" rather than a specific state of matter. Therefore, "zat keras" is the exception in this context.Rate this question:

Rumus Kalor yang diperlukan dalam perubahan suhu zat adalah...
- A.
Q = m x c x∆T.
- B.
Q = m x c
- C.
V = I x R
- D.
W = F x S
Correct Answer
A. Q = m x c x∆T.Explanation
The correct answer is Q = m x c x ∆T. This equation represents the heat energy (Q) required to change the temperature (∆T) of a substance, where m is the mass of the substance and c is its specific heat capacity. The equation Q = m x c x ∆T is derived from the principle of heat transfer, stating that the amount of heat energy transferred is directly proportional to the mass and specific heat capacity of the substance and the change in temperature.Rate this question:

Sifat suatu materi dapat dibedakan menjadi dua, yaitu ...
- A.
Sifat asam dan Sifat basa
- B.
Sifat Kimia dan Sifat biologis
- C.
Sifat fisika dan Sifat biologis
- D.
Sifat fisika dan Sifat kimia.
Correct Answer
D. Sifat fisika dan Sifat kimia.Explanation
The correct answer is "Sifat fisika dan Sifat kimia." This is because the question is asking for the two ways in which the properties of a material can be distinguished. Physical properties refer to characteristics that can be observed or measured without changing the identity of the substance, such as color, density, and melting point. Chemical properties, on the other hand, describe how a substance interacts with other substances and can only be observed through chemical reactions, such as flammability and reactivity. Therefore, the answer choice "Sifat fisika dan Sifat kimia" accurately represents the two categories of properties being discussed.Rate this question:

Sifat materi yang dapat dilihat secara langsung dengan indra.Berdasarkan pernyataan di atas Sifat apakah yang dimaksud...
- A.
Sifat Fisika
- B.
Sifat Fisika
- C.
Sifat Biologis
- D.
Semua jawaban salah
Correct Answer
A. Sifat FisikaExplanation
The correct answer is "Sifat Fisika" because the statement mentions that the material can be seen directly with the senses, which implies that it is referring to physical properties.Rate this question:
