Interpretation Introduction
Interpretation:
Calculations have to be carried out for
Concept Introduction:
Significant figures: The digits that are measured in a number including one estimated digit are called as significant figures.
The answers for those calculations that involve addition and subtraction will have the same number of decimal places as the original number with the fewest decimal places.

Anna was asked to identify and explain if the equation CO2 (l) → CO2 (g) was an endothermic or exothermic reaction. However she got it wrong. What is her error and what should the answer have been?
Anna's statement: The equation is an exothermic reaction because the energy is released from liquid CO2 to the surroundings to become gaseous CO2 causing the molecules to slow down.
In a coffee press, you combine solid coffee grounds and hot water. After a long time,
the ground coffee beans are still visible, and the water has turned into a rich dark
brown (some of the coffee has dissolved into the liquid). You push the filter in the
press down and pour out only the dark water into a cup. You then add milk and
sugar to the cup. You also notice that the filter must have a hole in it because there
are coffee grounds also in your cup. Calculate the degree of freedom in this system
(your cup) at equilibrium.
