Question
1.The pressure of an ideal gas in a sealed rigid container is directly proportional to its temperature only if the temperature is measured in K? True or False
2.If you increase the pressure on the surface of a can of water, you will increase the buoyant force on the objects placed in that water? T or F
3.If a uniform sphere is compressed to half of its original diamter, its mass remains the same but its density becomes 8 times greater? T or F
4.The amount of heat needed to raise the temperature of one mole of an ideal gas by 1.0K at constant volume is the same for all monotomic gases? T or F
5. The amount of heat needed to raise the temperature of one gram of an ideal gas by 1.0K at constant volume is the same for all monotomic gases? T or F
6. If the gauge pressure at a crtain depth in Lake Michigan is 3.5 atmospheres, the absolute pressure at that depth is 4.5 atm? T or F
Explanation / Answer
1) True
beacsue, we need to absolute temperature.
2) False
Beacause, Buoynat force depends only on volume of immersing body and densityof water.
3) True
because volume becomes 1/8 times
4) True
5) Flase
6) True
because, P_apsolute = Pgauge + 1 atm
= 3.5 + 1
= 4.5 atm
