Dear Mr. Chang, I am worried about your proposal to install a groundwater heating system in my daughter’s school.

I don’t think that water at a temperature of 30°C has enough energy to heat the school. If the school is too cold, the students won’t be able to focus on learning.

Respond to David Li’s letter. Explain how the groundwater system could heat the air in the school. Explain what would happen to the air temperature at Riverdale School if the groundwater system were used. Use the terms stability and change in your explanation.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
