Explanation The water boiling inside the cooker at a particular temperature states that at that temperature, the value of the saturated vapor pressure of the water is equal to the atmospheric pressure or the air pressure outside the cooker. Therefore, the saturated vapor pressure at 120 °C is same as the atmospheric pressure outside of the pressure cooker. According to the table 18.2, the saturated vapor pressure of the water at 120 °C is 1.99 × 10 5 Pa . Write the expression for the pressure in atm as. P atm = P Pa 1.01 × 10 5 atm (I) Here, P atm is the pressure outside the cooker in atm and P Pa is the pressure outside the cooker in Pascal

Kinetic Theory of Gas

The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all dire…

A high-speed lifting mechanism supports an 881 kg object with a steel cable that is 22.0 m long and 4.00 cm^2 in cross-sectional area. Young's modulus for steel is 20.0 ⋅10^10 Pa. Determine the elongation of the cable.

Namor, from Wakanda Forever, sits on a throne at the bottom of the ocean in a city called Talocan (and Atlantis in the comics). Assuming he, including his gold headdress, has a density of 1085 kg/m3 and that Namor is surrounded by salt water with a density of 1027 kg/m3, what is Namor’s normal force while sitting underwater? Take Namor’s mass as 285. kg and solve as if he has a uniform density.

To get there they need to travel through an area of salt-water, which seems to also be a magical portal, before arriving in a dry area. Judging by the time Maui and Moana spend falling through the water, it seems they dive 3440. ft deep. Assume the portal is non-magical salt-water, with a density of 1027 kg/m^3. Given that the air pressure above the portal is 1.013 ⋅10^5 Pa, what is the pressure when they are 3440. ft deep? 1 m = 3.28 ft. Moana would have a surface area of 1.30 m2. How much force would be acting on her at the bottom of this portal?
