What is the name of an ideal-gas process in which no heat is transferred? a. isochoric b. isentropic c. isothermal d. isobaric e. adiabatic

Adiabatic process

Explanation:

In an adiabatic process, their is no exchange of heat energy between the environment and they system. Here, no heat is gained or lost by the system. An adiabatic process is thermally insulated and no heat can come out of the system nor go into it. It is a difficult thermodynamic process to set up.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
