How much heat is involved in condensing 15.0 g of ethanol at its boiling point, then cooling it from its boiling point to a final temperature of 30.0°C?

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.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

the objects have the same charge.
