2. Heat changes during changes of state A. Boiling water (2.5 pts)
Water boils at 100 °C. You boil a pot containing 500 g of water for 10 minutes.
What is the temperature of the water after 10 minutes of constant boiling? (hint this question
does not require any math).
Explain or justify your answer by discussing heat and state change.
B (2.5 pts) Boiling off a pot of water
A pot containing 500 g of water is brought to a boil. The later heat of vaporization is for water H=2260 kJ/kg
How much heat will it take to completely boil the water (turn it all to steam) of water is brought to a boil.

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
