1st Semester Science Final Exam 100 Questions

Front

What are the three states of matter?

Back

Solid, Liquid, Gas.

Front

How do particles behave in a solid state?

Back

Particles are closely packed together and vibrate in place.

Front

How do particles behave in a liquid state?

Back

Particles are close together but can move past one another, allowing liquids to flow.

Front

How do particles behave in a gas state?

Back

Particles are far apart and move freely, filling the space available.

Front

What is the relationship between speed and distance traveled over time?

Back

Speed is calculated as distance divided by time.

Front

What is the definition of frequency in terms of waves?

Back

Frequency is the number of waves that pass a point in one second.

Front

How do radio waves differ from visible light waves?

Back

Radio waves have a lower frequency than visible light waves.

Front

What is the principle of balanced forces?

Back

When forces acting on an object are equal in size but opposite in direction, they balance each other, resulting in no change in motion.

Front

What is the definition of wavelength?

Back

Wavelength is the distance between successive crests of a wave.

Front

What happens to the frequency of light as its wavelength decreases?

Back

The frequency increases.
