What happens to the volume of a gas when its temperature increases and pressure remains constant?A. It increases. B. It decreases. C. It remains the same. D. It depends on the type of gas. 相关知识点: 试题来源: 解析 A。温度升高、压强不变时,气体体积增大。本题考查气体状态方程的知识...
A. It increases. B. It stays the same. C. It decreases. D. It first increases then decreases. 相关知识点: 试题来源: 解析 C。解析:随着海拔高度增加,气压会降低。因为随着高度升高,上方空气柱的重量减小。A选项气压是降低而非增加,B选项气压会改变而不是保持不变,D选项气压是持续降低而不是先增加...
What happens to the rate of photosynthesis as light intensity increases up to a certain point? A. It decreases. B. It remains the same. C. It increases. D. It becomes zero. 相关知识点: 试题来源: 解析 C。解析:随着光照强度增加到一定程度,光合作用速率也会增加,文章中有“As the intensity...
Describe what happens to the confidence interval estimate when the sample size decreases. Describe what happens to the value of the test statistic and its p-value when the value of bar x increases. What happens to the width of the confidence interval estimate when the sa...
When light passes from air to water, what happens to its speed? A. Increases B. Decreases C. Remains the same D. Depends on the color of light 相关知识点: 试题来源: 解析 B。解析:光从空气进入水中时,速度会减小。这是因为光在不同介质中的传播速度不同,光在折射率较大的介质中传播速度较...
What happens when supply increases and demand decreases? What happens when both supply and demand increase? What happens if price falls below the market clearing price? If price falls, what happens to the demand for a product? What happens to the equilibrium price when supply goes down?
It should be noted: the drop in CO2 doesn’t directly cause the whole drop in temperature. Other feedbacks occur when CO2 is eliminated. Water vapor condenses out as temps fall thus tanking its greenhouse effect & Albedo (reflected sun) increases bec. of ice growth = more cooling. ...
the less CO2it can store. (Test this out yourselfby comparing what happens when you open a warm versus a cold soda bottle). When the global temperature increases, the temperature of the ocean increases, and, absent other factors, the ocean will emit CO2into theatmosphere, causing CO2in the...
Consider what happens when x is nonpositive. The loop never executes, which means that in the unoptimized version, the variable count won’t be touched. However, in the manually optimized version, an unnecessary assignment from x to count is executed outside the loop! Moreover, if x wa...
What happens to blood pressure when the heart rate increases? A) increases B ) decreases C ) stays the same Blood Pressure: Blood pressure is a measure of the force that blood exerts on the walls of blood vessels in the cardiovascular system. It is ...
