Contoh Soal Tes Masuk Caltech (California Institute Technology)

Contoh Soal Tes Masuk Caltech California Institute Technology disajikan untuk membantu Anda mengenali pola soal serta tingkat kesulitan yang digunakan dalam proses seleksi, sehingga dapat dijadikan bahan latihan yang lebih efektif.

Soal 1
A tank contains 200 liters of a solution that is 30% salt. How many liters of pure water must be added to reduce the concentration to 20%?
A. 50
B. 75
C. 100
D. 120
E. 150

Jawaban: C
Pembahasan:
Initially, the amount of salt is 30% × 200 = 60 liters of salt. When water is added, the amount of salt remains the same but the total volume increases. Let x be the liters of water added. The new concentration is 20%, so:
60 / (200 + x) = 0.20
60 = 0.20(200 + x)
60 = 40 + 0.20x
20 = 0.20x
x = 100.

Soal 2
Which statement correctly describes an atom with atomic number 17 and mass number 35?
A. It has 17 neutrons and 18 electrons
B. It has 18 neutrons and 17 electrons
C. It has 17 protons and 18 neutrons
D. It has 35 protons
E. It has 18 protons and 17 neutrons

Jawaban: C
Pembahasan:
Atomic number represents the number of protons. Therefore, the atom has 17 protons.
Mass number = protons + neutrons
35 = 17 + neutrons
Neutrons = 18
A neutral atom has equal protons and electrons, so it has 17 electrons. Therefore, the correct description is 17 protons and 18 neutrons.

Soal 3
If 3x − 5 = 2(2x − 7), what is the value of x?
A. −3
B. −9
C. 9
D. 3
E. −1

Jawaban: C
Pembahasan:
First, expand the expression on the right side:
3x − 5 = 2(2x − 7)
3x − 5 = 4x − 14
Next, move the variables to one side and constants to the other side. Subtract 3x from both sides:
−5 = x − 14
Then add 14 to both sides:
9 = x.

Soal 4
Read the passage.
“Scientific progress often emerges from the careful observation of patterns in natural phenomena. Researchers analyze data repeatedly before drawing conclusions, ensuring that results are consistent and reproducible.”
What is the main idea of the passage?
A. Experiments are unnecessary in science
B. Scientific conclusions require repeated analysis of data
C. Natural phenomena are unpredictable
D. Observation is less important than theory
E. Science depends only on technology

Jawaban: B
Pembahasan:
The passage explains that scientific progress begins with careful observation of patterns in nature. It also highlights that researchers must analyze data repeatedly to ensure the results are consistent and reliable. Therefore, the main idea is that scientific conclusions are formed through repeated data analysis, making option B the correct answer.

Soal 5
Consider the statement:
“If a number is divisible by 4, then it is even.”
Which conclusion must be true?
A. If a number is even, it is divisible by 4
B. If a number is not even, it is not divisible by 4
C. All even numbers are divisible by 4
D. Odd numbers are divisible by 4
E. Some even numbers are divisible by 4

Jawaban: B
Pembahasan:
The statement means that every number divisible by 4 must always be an even number. In formal logic, the contrapositive of a statement has the same truth value as the original statement. Therefore, if a number is not even, it logically cannot be divisible by 4, which makes option B the correct conclusion.

Soal 6
A resistor of 6 Ω is connected to a 12 V battery. What is the current in the circuit?
A. 0.5 A
B. 1 A
C. 2 A
D. 6 A
E. 12 A

Jawaban: C
Pembahasan:
Using Ohm’s Law:
V = IR
I = V/R
= 12 / 6
= 2 A.

Soal 7
Solve for x:
x² − 7x + 10 = 0
A. x = 2 or 5
B. x = 3 or 4
C. x = 1 or 10
D. x = −2 or −5
E. x = 7 or 10

Jawaban: A
Pembahasan:
Factor the quadratic:
x² − 7x + 10 = (x − 2)(x − 5)
Thus
x = 2 or x = 5.

Soal 8
Which factor most strongly influences the rate of a chemical reaction?
A. Color of reactants
B. Temperature
C. Container shape
D. Volume of air
E. Type of glassware

Jawaban: B
Pembahasan:
Temperature strongly influences the rate of a chemical reaction because it increases the kinetic energy of the reacting particles. When the temperature rises, molecules move faster and collide more often, increasing the frequency of molecular collisions. In addition, a higher temperature allows more particles to reach or exceed the activation energy required for the reaction, which significantly speeds up the reaction rate.

Soal 9
A projectile is launched vertically upward with initial velocity 20 m/s. Ignoring air resistance, how long does it take to reach the highest point?
(g = 10 m/s²)
A. 1 s
B. 2 s
C. 3 s
D. 4 s
E. 5 s

Jawaban: B
Pembahasan:
At the highest point, velocity becomes zero.
Use:
v = u − gt
0 = 20 − 10t
10t = 20
t = 2 seconds.

Soal 10
Evaluate the derivative of f(x) = 3x² + 4x − 5.
A. 6x + 4
B. 6x − 4
C. 3x + 4
D. 2x + 4
E. 6x + 5

Jawaban: A
Pembahasan:
Using derivative rules:
d/dx (3x²) = 6x
d/dx (4x) = 4
d/dx (-5) = 0
So
f'(x) = 6x + 4.

Soal 11

Newton’s second law:
F = ma
a = F/m
= 10 / 2
= 5 m/s².

Soal 12
If log₁₀(1000) = ?
A. 1
B. 2
C. 3
D. 4
E. 10

Jawaban: C
Pembahasan:
log₁₀(1000) asks for the power of 10 that produces 1000.
10³ = 1000
Thus the value is 3.

Soal 13
Which type of bond forms when electrons are transferred between atoms?
A. Covalent bond
B. Hydrogen bond
C. Ionic bond
D. Metallic bond
E. Van der Waals bond

Jawaban: C
Pembahasan:
An ionic bond forms when one atom transfers one or more electrons to another atom. This transfer creates a positively charged ion (cation) and a negatively charged ion (anion). The electrostatic attraction between these opposite charges forms the ionic bond, which makes option C the correct answer.

Soal 14
The integral of 2x dx equals:
A. x² + C
B. 2x² + C
C. x + C
D. x²/2 + C
E. 4x + C

Jawaban: A

Using the power rule for integrals:
∫ xⁿ dx = xⁿ⁺¹ / (n+1)
Thus
∫2x dx = 2 × (x² /2) = x² + C.

Soal 15

A. 2 Ω
B. 5 Ω
C. 10 Ω
D. 12 Ω
E. 24 Ω

Jawaban: C
Pembahasan:
For series circuits, resistances add directly:
R_total = R₁ + R₂
R_total = 4 + 6 = 10 Ω.

Soal 16

A. 6
B. 12
C. 4
D. 8
E. 3

Jawaban: B

Derivative of x³ is
f'(x) = 3x²
Evaluate at x = 2
f'(2) = 3(2²) = 12.

Soal 17
Which phenomenon explains why a compass needle points toward Earth’s magnetic poles?
A. Electric current
B. Magnetic field
C. Chemical reaction
D. Nuclear force
E. Gravity

Jawaban: B
Pembahasan:
Earth behaves like a giant magnet that produces a magnetic field surrounding the planet. A compass needle is made of a small magnet that can freely rotate and respond to this magnetic field. As a result, the needle aligns itself with Earth’s magnetic field lines, causing it to point toward the magnetic poles, so the correct answer is B.

Soal 18
If a system receives heat but performs no work, what happens to its internal energy according to the first law of thermodynamics?
A. It decreases
B. It becomes zero
C. It increases
D. It remains constant
E. It disappears

Jawaban: C
Pembahasan:
According to the first law of thermodynamics, the change in internal energy of a system is expressed by the equation ΔU = Q − W, where Q is heat added to the system and W is the work done by the system. In this case, the system receives heat (Q is positive) but performs no work (W = 0). Therefore, all the added heat increases the internal energy of the system, making option C the correct answer.
