In the real world yes, like any fluid on earth, there's more pressure on the bottom of the container. However, when talking about ideal behavior of gases, we tend to neglect this. So if you actually tried to model huge amounts of gas, you'd have to take that into account. Logged ...
5. What pressure is required for a mole of an ideal gas to occupy a volume of 2 L at 300 K? b a. 100R b. 150R c. 200R d. 300R 相关知识点: 试题来源: 解析 bExplanation: The following values are given in the problem: V=2L,n=1mole , and T=300K . Using the ideal gas ...
What Causes Choked Flow? Choked flow usually happens when there is a high pressure drop across the valve. Choked flow begins when a pressure ratio is reached (1.8 for methane) and the gas velocity is at Mach 1 (767.2 MPH). There does not need to be a high flow rate for choked flow ...
Changing the temperature affects pressure in a closed container. Raise the temperature, and the pressure increases. This occurs due to the increased movement of the gas molecules. Double the temperature, and you double the pressure. This explains why aerosol cans have warnings about exposure to hea...
When a fluid moves from a larger diameter tube to a smaller one, why then does the pressure not increase as the ideal gas law would predict? A decrease in cross sectional area is not a decrease in volume. Area and volume are two different things. I'm also confused about flow ...

What causes the eruption in the experiment? A. The combination of vinegar and baking soda produces carbon dioxide gas. B. The heat from the reaction. C. The pressure inside the bottle. D. The color of the food coloring. 相关知识点: ...
Robert Boyle demonstrated that there is an inversely proportional relationship between the pressure and volume of a gas as long as temperature is kept constant. This means that when pressure increases, volume decreases, and when pressure de...
It is defined as the boiling point of a liquid, at the temperature at which its vapor pressure is equal to the pressure of the gas over the liquid. As the temperature is increased, the vapor pressure increasesAnswer and Explanation:
