If a gas is heated at constant pressure,its volume is proportional to the temperature.这个是对的.(Volume = Constant * Temperature,V= nR/P * t)但是 volume increase指delta V.(V的变化)所以不一样... 分析总结。 ifagasisheatedatconstantpressureitsvolumeincreaseisproportionaltothetemperature这个判断...
发样律安发样律安It becomes zero.发样律安发样律安 相关知识点: 试题来源: 解析 C。解析:If the temperature of a gas increases while the volume remains constant, the pressure will increase,即当气体温度升高而体积不变时,压强会增大。反馈 收藏 ...
If the amount of gas increases, but the pressure and temperature stay fixed, what happens to the volume? What is the relevant gas law? Avogadro law For a system containing a certain amount of a gas, when the pressure and the temperature of...
A closure device (13) in a gas line (12) leading into the second nozzle (14) can be used to shut off the supply of gas to the nozzle if a pressure differential between the gas pressure in this line and the pressure chamber (18) falls below a given value. A gas and a liquid are...
(a) 2 moles of an ideas gas is heated at constant pressure so that its temperature increases from27∘Cto127∘C. Find work done by the gas. (b) In a process, the volume of gas increases from 1000 cc to 2000 cc at constant pressure 100 kPa. Find work done by the gas. ...
If we increase the pressure on a gas, it will ___. A. expand B. contract C. disappear D. explode 相关知识点: 试题来源: 解析 B。如果增加气体的压力,气体将会收缩。选项 A“expand”膨胀不符合;选项 C“disappear”消失不可能;选项 D“explode”爆炸不太可能。反馈 收藏 ...
Additional answer space if required:(b)0.24mol of gas is contained in a cylinder as represented in Fig. 38.2. The gas is trapped by a disc of negligible mass so that the pressure in the cylinder is equal to the atmospheric pressure outside the cylinder. The disc can move up and down ...
If the amount of gas increases, but the pressure and temperature stay fixed, what happens to the volume? What is the relevant gas law? If the volume increases, but the temperature and the number of moles stay constant, what happens to the pressure?...
When the temperature of a gas is increased, it is either accompanied by an increase in pressure if the gas is enclosed in a container, oran increase in volume if the gas is able to expand. 选项: A、 When the temperature of a gas is increased, it is either accompanied by an increase ...
Answer to: If the initial pressure of a gas is 1.2 atm and it occupies a volume of 30 mL, what will the pressure be if the volume is increased to...
