Basic Concepts in Chemistry and Physics

Front

What is temperature a measure of?

Back

Temperature is a measure of how hot or cold something is, indicating the average kinetic energy of the particles in a substance.

Front

How does particle movement relate to temperature?

Back

Faster particle movement results in higher temperature, while slower movement results in lower temperature.

Front

What units are used to measure temperature?

Back

Temperature is measured in degrees Celsius (°C), Fahrenheit (°F), or Kelvin (K).

Front

What is plasma?

Back

Plasma is the fourth state of matter, where a gas gains enough energy to break apart into charged particles, such as positive ions and free electrons.

Front

Why does plasma conduct electricity?

Back

Plasma conducts electricity due to the presence of charged particles.

Front

What is a Bose-Einstein condensate (BEC)?

Back

A BEC is a state of matter at extremely low temperatures where bosons occupy the same lowest energy state, acting like a single 'super-atom.'

Front

What is the heat of fusion?

Back

The heat of fusion is the energy needed to change a substance from solid to liquid at its melting point without changing its temperature.

Front

What is the heat of vaporization?

Back

The heat of vaporization is the energy needed to change a substance from liquid to gas at its boiling point without changing its temperature.

Front

What is vaporization?

Back

Vaporization is the process where a liquid changes into a gas, either through evaporation or boiling.

Front

What is a proton?

Back

A proton is a positively charged particle found in the nucleus of an atom, with a mass of about 1 atomic mass unit (amu).
