Flashcards

What is absolute zero?

The absolute zero is the lowest possible temperature that can be reached. At this point, the particles of a substance have minimal kinetic energy and cease all motion. It's considered as the theoretical zero point of temperature.

What is the boiling point of water in Kelvin?

373.15 Kelvin is the boiling point of water on the Kelvin scale. The Kelvin scale starts at absolute zero and uses the same size for degrees as the Celsius scale.

Which temperature scale has only positive values?

The Kelvin scale has no negative temperature values, unlike Celsius or Fahrenheit. The lowest possible value on the Kelvin scale is absolute zero, representing complete lack of energy.

What is the freezing point of water in Fahrenheit?

The freezing point of water on the Fahrenheit scale is 32 degrees Fahrenheit. The Fahrenheit scale is based on the freezing and boiling points of water, but uses different numerical values than Celsius.

What happens to temperature when particles move slower?

Temperature is directly related to the movement of particles. When particles move slower, they possess less kinetic energy, resulting in a lower temperature.

The Kelvin scale has 180 degrees between the freezing and boiling points of water.

The Kelvin scale has 100 degrees between the freezing and boiling points of water, unlike the Celsius scale which also has 100 degrees. This means the size of a degree is the same in both scales.
