Question

thermodynamics:

Explain why the properties of liquids can be estimated (with reasonable accuracy) as a function of temperature only

Answer 1

The density of a liquid is affected by change in temperature. Increasing the temperature in general decreases it's density and vice versa. During experimentation, with regard to volume, liquids generally expand when heated and contract when cooled. More simply,liquids increase in volume with substantial increase in temperature and decrease in volume with significant decrease in temperature.(exception: water has temperature between 0 degree celsius and 4 degree celsius.

A liquid is defined as fluid matter having no fixed shape but a fixed volume;it is one of the three states of matter. A liquid had the ability to flow as well as take the shape of a container. It resists compression and maintains a fairly constant density. Given that temperature directly affects the kinetic energy of molecules in a liquid,the effects of temperature on liquid can be described in terms of kinetic-molecular theory.

This way,temperature plays an important role in explaining the above important properties of liquids.
