a. Notice the difference between the August high in San Francisco and Sacramento. Why is it much hotter in the summer in Sacramento?
b. Notice the difference between the January low in San Francisco and Sacramento. How might the heat capacity of the ocean contribute to this difference?

c) 2C°
d) 4C°
The summer before coming to school, you are lucky enough to get a job making coffee at Starbucks,but you tell your parents and friends you have secured a lucrative position as a “java engineer”. An eccentricchemistry professor (not mentioning any names) stops in every day and order 250.0 mL of house coffee at precisely95 °C. He then adds enough milk at 10.0 °C to drop the temperature of the coffee to 90.0 °C. Calculate the amount ofmilk (in mL) the professor must add to reach this temperature. (Assume coffee and milk have the same specific heatcapacity: 4.186 J/g °C. Assume that they also have the same density: 1.000 g/mL).
Chemistry
A 2.50 g sample of copper (Cs copper = 0.385 J/(g °C)) that had been heated to 100. °C was placed in a flexible container with an initial volume of 1.5 L and an initial temperature of 25 °C that was filled with air at a pressure of 1.0 atm. Assume that air acts as an ideal linear gas and no heat energy enters or exits the container.
What is the temperature when thermal equilibrium is reached? Enter the temperature in °C. (Round to the nearest integer.) (Do NOT enter units.)
