The temperature at which liquid nitrogen boils (at atmospheric pressure) is 77 K. Express this temperature...
Liquid nitrogen has a density of 0.808 g/mL and boils at 77 K. Researchers often purchase liquid nitrogen in insulated 185 L tanks. The liquid vaporizes quickly to gaseous nitrogen (which has a density of 1.15 g/mL at room temperature and atmospheric pressure) when the liquid is removed from the tank. Suppose that all 185 L of liquid nitrogen in a tank accidentally vaporized in a lab that measured 10.00 m times 10.00 m times 3.50 m. Part A What...
The boiling point of liquid nitrogen is 77.4 K at atmospheric pressure. (a) What is this temperature on the Celsius scale? °C (b) What is this temperature on the Fahrenheit scale? °F
7. (15 pts) Liquid nitrogen boils at 77 K at 1 atm. A common demonstration of the Lei- denfrost effect is to stick stick your finger into a dewar of liquid nitrogen. Assume that your finger can be modeled as a horizontal cylinder with diameter 1.0 cm, length 5.0cm, and skin temperature 32°C. Use 100 K for the properties of the nitrogen vapor. Neglect radiation. The density of liquid nitrogen is 1.251 kg/m', and its enthalpy of vaporization is 1.99x10J/kg....
Liquid aluminum has a boiling point of 2450°C at atmospheric pressure. (a) Express this temperature in degrees Fahrenheit. (b) Express this temperature in kelvins.
1.A gas container is initially at 47 mm Hg and 77 K (liquid nitrogen temperature.) What will the pressure be when the container warms up to room temperature of 25 ˚C?
When the vapor pressure of a liquid equals atmospheric pressure, the temperature of the liquid equals Group of answer choices the boiling point of the liquid the normal boiling point of the liquid 100° C 273 K
The boiling temperature of nitrogen at atmospheric pressure at sea level (1 atm pressure) is -196°C. Therefore, nitrogen is commonly used in low-temperature scientific studies since the temperature of liquid nitrogen in a tank open to the atmosphere will remain constant at -196°C until it is depleted. Any heat transfer to the tank will result in the evaporation of some liquid nitrogen, which has a heat of vaporization of 198 kJ/kg and a density of 810 kg/m3 at 1 atm....

Liquid nitrogen can be used to cool down objects. The following data of liquid nitrogen and nitrogen gas can be used around its boiling point: Furthermore, it is given that the molar heat capacity of N_2 (g) is 29.0 J/K, which Is constant over the considered temperature range for N_2 in gas phase. Calculate the boiling point of nitrogen at atmospheric pressure. What is the molar heat of vaporization for N2 at the boiling point and atmospheric pressure? 2.0 moles...
Find the increase in entropy (in J/K) of 4.20 kg of liquid nitrogen that starts at its boiling temperature, boils, and warms to 25.0°C at constant pressure. 14530 J/K
