16. You have 2 beakers: one contains 30 g of water (1) at 60°C & the other has 30 g of ethyl alcohol (1) at 60°C. How many Joules of heat is required to heat each beaker up to 85 °C?
(Specific heat of alcohol: 2.44 J/(g*°C), Boiling point = 78.4 °C, Latent heat of Vap, = 841 J/g)
Make a phase change diagrams for each substance
b. Clearly show each calculation that is needed.
a.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
