Question

According to most scientists our world is divided in what manner? Explain what is necessary in order for a thermodynamic to occur. Why is it unlikely for a cup of coffee whose temperature is 33 degree C to reach a temperature below room temperature? Explain why it is possible for internal energy to be studied solely from its change in enthalpy for most chemical processes at constant pressure. Explain the significance of q_n = -q_sur. What are the two systems being investigated in this experiment? What components make up the surroundings in this experiment?

Explanation / Answer

Q1.

The world is divided in Energy and Matter

Q2.

in order for a process to occur, we must have:

An increase in entropy in the universe

Q3

Because:

1 - it will violate zeroth law of thermodynamics, which states that heat flows ftrom high T to low T

2 - the universe will get ordered, i.e. chaos/entropy decreases, which is no tpossible

Q4

because:

H = U + PV

so, if P constant, and V is almost zero, then H approx U

Q5

Qsystem = -Qsurrounding:

the heat absorbed by system will be lost by surroundings

Q6,Q7 --> sytem is typically our beaker, surrounding is typically the outside container
