Physical Science
Test Questions
Course Introduction
Physical Science is an introductory course that explores the fundamental concepts and principles of physics and chemistry, providing a foundational understanding of how the physical world operates. Students will examine topics such as matter, energy, motion, forces, the structure of atoms, properties of elements and compounds, and basic laws of physics and chemistry. Through experiments, problem-solving, and observation, learners will develop scientific reasoning skills and appreciate the relevance of physical science in everyday life and modern technology. The course prepares students for more advanced studies in science and fosters a deeper curiosity about the natural world.

Q1) Why does the Sun brighten with time?
A) as time progresses, helium starts to fuse in the core, in addition to hydrogen, leading to an increase in brightness
B) as hydrogen is converted into helium in the core, the number of hydrogen nuclei decreases, decreasing the fusion rate. To maintain the balance with gravity pressing inward, the core compensates by shrinking and heating up
C) as time progresses, more and more heat is trapped inside the core, leading to an increase in brightness
D) as hydrogen is converted into helium in the core, the number of hydrogen nuclei decreases, decreasing the fusion rate. To maintain the balance with gravity pressing inward, the core compensates by expanding and cooling
Q2) What is a possible reason why Venus does not have plate tectonics?
