When pressure increases and temperature decreases, density becomes highest. Therefore, the density of the neon will be highest at a temperature of 0∘C(lowest temperature) and pressure of 2 atm (highest pressure).
Specific heat is the amount of energy required to change the temperature of the substance. This high specific heat of water enables the moderation of climate on Earth and organisms can regulate their body temperature.
Expansion of water when it is cooled from four degrees Celsius to zero degrees Celsius is observed. The density of water decreases instead of increasing as the temperature falls from 4 degrees to 0 degrees.
