a) How much heat would be liberated by a yeast culture that ferments 1.00 kg of
glucose under standard conditions? (Use textbook Table 2C.6 and 2C.7 in this
calculation.)
b) Calculate

C, 0.975 atm in a thermally
insulated syringe is injected into a thermally insulated tube having a volume of 5.00 mL.
a) If this process was carried out reversibly, what would be the final temperature of the
gas in the tube?
b) What is the final temperature of the gas in the tube if this compression was done by
the application of a constant external pressure of 3.65 atm?
Question 3.
Lithium batteries are widely used in portable electronic devices and electric vehicles.
However, operation of these batteries tends to generate heat, which can raise the
temperature of the device.
The amount of energy required to raise the temperature of
lithium is temperature dependent, and follows the relationship:
