We hypothesize that if we increase the pressure on a gas, its volume ___ decrease. A. will B. must C. should D. can 相关知识点: 试题来源: 解析 A。本题考查对科学实验假设中条件与结果的对应。增加气体的压力,通常情况下气体体积会减小,这里用“will”表示将会发生。“must”表示肯定的推测,语...
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 ...
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, or an 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...
aIf the measured pressure reaches the set point of the SSV, a release mechanism is triggered and the SSV closes the valve on the inlet pressure side of the regulator.This closing function completely blocks the forward movement of gas past the SSV. 如果被测量的压力到达SSV的凝固点,发行机制被触...
Even If Oil Output Rises, Gas Prices Adjust Slowly ; under Pressure from US, Oil-Rich Nations Agree They Should Pump More Oil
In this case, we are left to assume that the volume is kept constant, so V1=V2 and they cancel. This gives us P1/T1=P2/T2 The only thing we have to be careful of is that the temperature must be absolute (in kelvins) for all of the gas laws. Solving for T2...
If the gas pressure behind the ring is built up too slowly, and thereby exerts an inadequate outward pressureIn such a case, the combustion gas can penetrate between the liner and ring, and violently force the ring inwards, in the grooveWhat result will this type of sudden "shock" loading...
Kärcher holds that honor, its name synonymous with pressure washers. If you imagine that such success leaves nowhere to go, think again! The super-compact and highly portable OC 3 Foldable takes the pressure washer to new places – literally! 很少有品牌获得如此显赫的地位,以至于它们的名字变成...
The law states the relationship between temperature and volume of the gas when the pressure remains unchanged. When there is an increase in temperature, the gas expands, and hence, the volume of the gas rises. The law is also known as the law of ...
