You can smell a burning scented candle across a room because
the gas molecules move about the room
At 25oC three moles of a gas occupy a volume of 4.0 L at 1.9 kPa If the volume decreases to 2.0 L what will the new pressure be
A device that absorbs and draws heat from a hot object dispersing it into the surroundings is which one of the following
Entropy is the measure of the amount of disorder in a system
Is Thermodynamics the study of the relationships among heat work and other forms of energy
Yes this is correct.
"Thermodynamics is the study of the relationships among heat, work and other forms of energy."
With which below would Ronald Reagan most likey have agreed
Molecular mass equals 2vapour density
vapor density =density of gas/density of hydrogen gas
=mass of a certain vol. of gas/mass of same vol. of hydrogen gas
=mass of n molecules of gas/mass of n molecules of hydrogen gas
=mass of 1 molecule of gas/mass of 1 molecule of hydrogen gas
=molecular mass of gas/molecular mass of hydrogen gas
=molecular mass/2
2 x vapor density=molecular massAccording to Charles s law if the temperature of a gas decreases the volume
It isn't possible to transfer heat from an object at a lower temperature to another object at a higher temperature unless
It isn't possible to transfer heat from an object at a lower
temperature to another object at higher temperature unless work is
done to the system. An example of this is a refrigerator.
