You are using a 680 W microwave to heat 700 mL of olive oil. If the initial temperature of the oil is 18 C,
what is the temperature after 2 minutes in the microwave? Assume the microwave is 88% efficient. Express
this temperature in Celsius.
Use 1.97 J/gK for the specific heat of olive oil. The specific gravity is 0.915.
The data in the following table are from a constant volume gas thermometer experiment. The volume of the gas was kept constant, while the temperature was changed. The resulting pressure was measured.

Explain. FIGURE 19.22 1 Gas in the constant-volume gas thermometer is at Ti, and the mercury in the manometer is at height hi above the gasmercury boundary. 2 The thermometer is placed in thermal contact with an object, and its temperature increases. The increased temperature increases the gas volume. 3 By raising the right-hand tube of the mercury manometer, the gas volume is restored to its original size. The mercury is now at hi + h above the gasmercury boundary. This increase in height is a result of the increase in gas temperature and pressure.arrow_forwardYou are working as a research assistant for a professor whose research area is thermodynamics. He points out to you that Daniel Fahrenheit used the best estimate of normal human body temperature as one of the points indefining the original Fahrenheit temperature scale. On the revised scale we now use, normal human body temperature is 98.6°F. Your professor proposes a new scale on which normal human body temperature would be exactly 100°N, where the unit °N is a degree on the New scale. The temperature of freezing water would be 0°N, as on the Celsius scale. Your professor asks you to determine the following temperatures on his new scale: (a) absolute zero, (b) the melting point of mercury (-37.9°F), (c) the boiling point of water, and, for publicity at his expected future press conference, (d) the highest recorded air temperature on the Earth’s surface, 134.1°F on July 10, 1913, in Death Valley, California.arrow_forward
