Jeff has 10 grams of water and 10 grams of vegetable oil in separate containers. Both liquids have a temperature of 24°C. Jeff heats both liquids over a flame for five minutes. When he’s finished, he discovers that the temperature of the oil increased more than the temperature of the water. What can Jeff conclude from this experiment?
A. Vegetable oil is a better conductor of heat than water.
B. Water is a better conductor of heat than vegetable oil.
C. Vegetable oil has a higher heat capacity than water.
D. Vegetable oil has a lower heat capacity than water.
E. Vegetable oil is a good insulator.

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i. e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
