For air, use a reference state of air at 25°c and 1 atm, and for water a reference state of liquid water at 0.01°c and answer the following questions. assume that changes in enthalpy due to pressure are insignificant. what is the specific enthalpy of air at 25°c?
answer these in units of kj/mol
what is the specific enthalpy of air at 25°c?
what is the specific enthalpy of air at 0.01°c?
what is the specific enthalpy of water vapor at 25°c?
what is the specific enthalpy of water vapor at 0.01°c?
what is the specific enthalpy of liquid water at 0.01°c?
what is the rate of heat added to the ac unit? kj/s

answer is d because it is trust me

a c d and f

just finished the assignment

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
