A Fahrenheit and a celsius thermometer are both immersed in a fluid and indicated identical numerical readings. What is the temperature of the fluid expressed in degrees Kelvin?

A closed 1 L water bottle contains air at standard temperature and pressure. The bottle is left in a room for a few hours, and the sun heats up the bottle to 30oC. What is the new pressure inside the bottle? Give an answer in atm with 3 digits of precision behind the decimal.

According to the Ideal Gas Law, PV = kT, where P is pressure, Vis volume, T is temperature (in Kelvins), and k is a constant of proportionality. A tank contains 2000 cubic inches of nitrogen at a pressure of 26 pounds per square inch and a temperature of 600 K. Determine the EXACT value of k.

The volume of an automobile tire is 2.5x10^-2m^3. The pressure of the air in the tire is 3.3 atm and the temperature is 25C°. What is the mass of air in grams? The mean molecular mass of air is 29g. Calculate to 2 decimals.

Three measurements for the boiling point of water are 100.4 °C, 100.1 °C, and 100.0 °C. The accepted boiling point is 100.0 °C. (a) What are the estimated digits? The estimated digits are (b) How many figures are certain? figures are certain in each measurement. and respectively.

1.21 A team is designing a helium-filled balloon that will fly to an altitude of 80,000 ft. As the balloon ascends, the upward force (buoyant force) will need to exceed the total weight. Thus, weight is critical. Estimate the weight (in newtons) of the helium inside the balloon. The balloon is inflated at a site where the atmospheric pressure is 0.89 bar and the temperature is 22°C. When inflated prior to launch, the balloon is spherical (radius 1.3 m) and the inflation pressure equals the local atmospheric pressure.

Assume an oil drop has a volume of 0.15 cm^3 . If you had Avogadro’s number (6.022 x 1023) of oil drops that just filled a cubic box, what would the edge length of the box measure, in centimeters?

Calculate the average density of the following astronomical body:  Jupiter. Where does the value fit among those listed in the table below? Look up the density of a typical rock, such as granite in another source and compare the density of Jupiter to it. Table: Densities of Some Common Substances at Standard Temperature (0°C) and Pressure (Atmospheric) Substance ρ (kg/m3) Substance ρ (kg/m3) Air 1.29 Ice 0.917 ✕ 103 Aluminum 2.70 ✕ 103 Iron 7.86 ✕ 103 Benzene 0.879 ✕ 103 Lead 11.3 ✕ 103 Copper 8.92 ✕ 103 Mercury 13.6 ✕ 103 Ethyl Alcohol 0.806 ✕ 103 Oak 0.710 ✕ 103 Fresh Water 1.00 ✕ 103 Oxygen gas 1.43 Glycerin 1.26 ✕ 103 Pine 0.373 ✕ 103 Gold 19.3 ✕ 103 Platinum 21.4 ✕ 103 Helium gas 1.79 ✕ 10−1 Sea Water 1.03 ✕ 103 Hydrogen gas 8.99 ✕ 10−2 Silver 10.5 ✕ 103

An arctic weather balloon is filled with 40.7 L of helium gas inside a prep shed. The temperature inside the shed is 7.°C. The balloon is then taken outside, where the temperature is −11.°C. Calculate the new volume of the balloon.You may assume the pressure on the balloon stays constant at exactly 1atm. Round your answer to 3 significant digits.

At crime scenes, the time of death is often determined by the temperature of the liver. Let H(t) be the temperature of the body, and S be the surrounding temperature. Newton's heating-cooling law states that the rate of change in the temperature, H, is proportional to the difference between the object and the surrounding temperature. If it is 75 degrees outside and a living person is 98.6 degrees, use Newton's cooling law to determine how long a body that has temperature 76 degrees has been left outside if at time t = 12 hours, H(12) = 80. Note that we need two measurements as different masses will cool at different rates. O 23.42 O 24.35 O 25.694 O 31.385
