12 The atmospheric pressure is 100 kPa. What is the average force experienced at the bottom of the water tank with length 0.5 m, width 0.4 m and depth 0.6 m? (Density of water is 1000 kg/m3.) D A 720 N B1200 N C 12720 N D 21200 N 相关知识点: 试题来源: 解析 D 反馈 收...
Barometric pressure is the pressure of the air on objects. On the Earth, the normal barometric pressure is measured in relation to sea level. There are many units for air pressure, Pa or kPa being the SI units for this measurement.
Derive an expression between density, pressure, and volume. The density of water is 1,000 kg/m^2. Calculate the depth of water in a dam when the pressure at the bottom is 120 kPa and g = 9.8 m/s^2. 1. You measure the gauge press...
The pressure dependence curves of the average boiling points, formed here on the basis of average boiling points obtained in the pressure range from 5 kPa to atmospheric pressure, can be reliably described by the integrated Clausius-Clapeyron equation. To increase the accuracy in determining the ...
Processing conditions used for this preferred template synthesis included a temperature of about 1050° C., a total pressure of (kpa) of about 1.3; CO2 (cm3/min) of 240; CO2 (cm3/min) of 250; and HCl (cm3/min) of 20 for producing HfCl3. The surface pretreatment by the H2+CO2 gas...

What pressure is exerted by this gas? A 10 L container holds 4 moles of gas at a pressure of 305 kPa. What is the temperature in Kelvins? At what temperature average speed of nitrogen will be same as the RMS speed of oxygen at 300 kelvin? At what temperatu...
Suppose 1400 J of heat are added to 6.3 mol of argon gas at a constant pressure of 120 kPa. (Assume that the argon can be treated as an ideal monatomic gas.) (a) Find the change in internal energy. (b) Find the change in temperat...
