What is the chemical explanation as to why salts of water borne minerals scale on the inside of water piping, specifically carbon steel or stainless steel
Find out the mass of the air in a room 3.00m by 4.00m by 5.00m given that the temperature is 200 C at atmospheric pressure (1atm = 101000 Pa)
For a diatomic gas near room temperature, the internal partition function is simply the rotational partition function multiplied by the degeneracy Ze
A balloon filled with 40 moles of He at 3 atm pressure and at room temperature (300 K) expands isothermally from a volume Vi to a volume Vf
A small container of gas undergoes a thermodynamic cycle. The gas begins at room temperature. First the gas expands isobarically until its volume doubles.
Consider an ideal 2-state paramagnet. The entropy is given by:
