There are two separate containers, each filled with a different ideal gas. Container A contains helium (He) and container B contains neon (Ne). Both have the same mass density and the same absolute pressure. If the gas in container A is at a temperature of -110.01 °C, what is the temperature of the gas in container B, in Kelvin?
A clown at a birthday party has brought along a helium cylinder, with which he intends to fill balloons. When full, each balloon contains 0.00440 m3 of helium at an absolute pressure of 1.10 x 105 Pa. The cylinder contains helium at an absolute pressure of 1.90 x 107 Pa and has a volume of 0.00320 m3. The temperature of the helium in the tank and in the balloons is the same and remains constant. What is the maximum number of people who will get a balloon?
During the summer after your first year, you are lucky enough to get a job making coffee at Starbucks, but you tell your parents and friends that you have secured a lucrative position as a “java engineer.” An eccentric chemistry professor stops in every day and orders 250 mL of house coffee at precisely 95°C. He then adds enough milk at 4°C to drop the temperature of the coffee to 90°C.
Calculate the amount of milk (in mL) the professor must add to reach this temperature.
(Assume coffee and milk have the same specific heat capacity: 4.186 J/g°C. Assume that they also have the same density: 1.0 g/mL)
Calculate the heat lost by the coffee when its temperature is decreased from 95°C to 90°C.

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_forward
