Predict what would happen to the carbon cycle if plants were not
a part of it. Provide an explanation for your prediction.
Hot & Cold compress
1. What are compresses?
2. What conditions would benefit from hot compresses?
3. What conditions would benefit from cold compresses?
4. How do you create a compress?
A hot lump of 32.9 g of iron at an initial temperature of 55.9
°C is placed in 50.0 mL of H2O initially at 25.0 °C and allowed to
reach thermal equilibrium. What is the final temperature of the
iron and water given that the specific heat of iron is 0.449
J/(g·°C)? Assume no heat is lost to surroundings.
A hot lump of 43.0 g of iron at an initial temperature of 62.6
°C is placed in 50.0 mL of H2O initially at 25.0 °C and allowed to
reach thermal equilibrium. What is the final temperature of the
iron and water given that the specific heat of iron is 0.449
J/(g·°C)? Assume no heat is lost to surroundings.
Describe what would be a type I error and what would be a type
II error:
A restaurant claims more than 42% of its new patrons return at
least once within a month.
What are the differences between type I and type II
diabetes? When the body does not have enough insulin to convert
carbohydrates into energy, what happens to the vascular system? Why
are people with diabetes so much more vulnerable to heart disease
and some cancers?
A 25 g piece of hot iron is dropped into a glass of ice water
containing 15.0 g of ice and 50.0 g of water. If the iron loses
8.00 kJ of energy to the ice water in achieving equilibrium, what
is the equilibrium temperature? ∆Hfus = 6.01 kJ/mol
A piston–cylinder device contains steam that undergoes a
reversible thermodynamic cycle. Initially the steam is at 400 kPa
and 350oC with a volume of 0.3 m3. The steam is first expanded
isothermally to 150 kPa, then compressed adiabatically to the
initial pressure, and finally compressed at the constant pressure
to the initial state. Determine (a) the net work and heat transfer
for the cycle after you calculate the work and heat interaction for
each process and (b) show the cyclic...
