Mar 7, 2025 · 1 ATM (atmosphere) is a unit of pressure, not volume, so it does not directly correspond to liters. However, at standard temperature and pressure (STP), 1 ATM is equivalent to 1.01325 x 10^5 ...

Question: One mole of ideal gas initially at 300 K is expanded from an initial pressure of 10 atm to a final pressure of 1 atm. Calculate ΔU, q, w, ΔH, and the final temperature T2 for this expansion carried out according to each of the following paths. The heat capacity of an ideal gas is cV=3R/2. a. An isothermal, reversible expansion b.

Apr 15, 2016 · In this case we can look up the value of mm-Hg for 1 atm (Atmosphere (unit) ): 1 " atm" = 760. "mm-Hg" Then we can turn this into a conversion factor: (1 " atm") /( 760. "mm-Hg") or ( 760. "mm-Hg")/(1 " atm") We can now apply the conversion by starting with the unit we have, and selecting the factor that cancels that unit and leaves the one we ...

Jun 10, 2024 · The volume of 1.00 kg of helium can be calculated using the ideal gas law. First, convert the pressure to atm (735 torr = 0.968 atm) and the temperature to Kelvin (5.00°C + 273.15 = 278.15 K).

A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 704 mm Hg. Express this pressure in atmospheres, kilopascals, torrs, pounds per square inch, and pascals. Hint: 1 atm = 101.3 kPa = 760 torr = 760 mm Hg = 14.69 psi = 1.013 x 105 Pa mm Hg atm kPa torr psi Pa

Consider the phase diagram for iodine shown here. a. What is the normal boiling point for iodine? b. What is the melting point for iodine at 1 atm? c. What state is present at room temperature and normal atmospheric pressure d. What state is present at 186 °C and 1.0 atm? Pc 1 atm Pressure (not to scale) 113.69184.4 CMZO Temperature not to scale)

A prototype automobile is designed for cold weather in Denver, CO (-10 °C, 83 kPa). Its drag force is to be tested on a one-seventh-scale model in a wind tunnel at 150 mi/h, 20 °C, and 1 atm. If the model and prototype are to satisfy dynamic similarity, what prototype velocity, in mi/h, needs to be matched? Comment on your result

Air at 1 atm and 20°C is flowing over the top surface of a 0.95-m-long thin flat plate. The air stream velocity is 46 m/s and the plate is maintained at a constant surface temperature of 180°C. The properties of air (1 atm) at the Tf = (20°C + 180°C)/2 = 100°C are k = 0.03095 W/m∙K, ν = 2.306× 10−5 m2/s, and Pr = 0.7111.

Question: How many grams of phosphorus (P4) are needed to completely consume 90.5 L of chlorine gas according to the following reaction at 25 °C and 1 atm? phosphorus (P4) ( s ) + chlorine ( g ) ---> phosphorus trichloride ( l ) ___ grams phosphorus (P4) How many grams of carbon disulfide are needed to completely consume 32.5 L of chlorine gas according to the

An underwater exploration vehicle submerges to a depth of 1000ft. If the atmospheric pressure at the surface is 1 atm, the water density is 64.4 lb/ft^3, and g = 32.2 ft/s^2, determine the pressure on the vehicle, in atm.
