The pressure differential of water across the surface of a spherical droplet of radius 200 nm at 20 °C has to be calculated. Concept introduction: Liquids are formed due to particles being apart for more than a few diameters. These molecules interact to form the liquid phase. The thermodynamic properties of liquids depend on the molecular interactions between the constituent particles as liquids have properties intermediate to solids and gases. The attraction between the surface molecules in a liquid is termed as surface tension. Due to surface tension, the molecules try to attain a minimum surface area.

ох 4-tert-butyl oxy cyclohex-1-ene Incorrect, 1 attempt remaining The systematic name of this compound classifies the -OR group as a substituent of the hydrocarbon, which is considered the principal functional group. The ether substituent is named with the suffix 'oxy'. The general format for the systematic name of a hydrocarbon is: [prefix/substituent] + [parent] + [functional group suffix] Substituents are listed in alphabetical order. Molecules with a chiral center will indicate the absolute configuration at the beginning of its name with the R and S notation.

5. Compressibility (6 points total). The isothermal compressibility is a measure of how hard/easy it is to compress an object (how squishy is it?) at constant temperature. It is др defined as Br=-()=-(200²)T' (a) You might wonder why there is a negative sign in this formula. What does it mean when this quantity is positive and what does it mean when this quantity is negative? (b) Derive the formula for the isothermal compressibility of an ideal gas (it is very simple!) (c) Explain under what conditions for the ideal gas the compressibility is higher or lower, and why that makes sense.
