Viscosity of liquids decreases as the temperature rises. Why?
This is because, at high temperature, molecules have high kinetic energy and can overcome the intermolecular forces to slip fast one another between the layers.
What is atmospheric pressure?
Which state of matter has a definite volume but no definite shape?
What is absolute temperature?
What is the absolute zero temperature?
Can absolute zero temperature be attained for a gas?
How pressure of a given sample of gas is related to absolute temperature at constant volume?
How is the pressure of a gas related to the number of molecules of the gas at constant temperature and volume?
What is standard (or normal) temperature and pressure (STP)?
