I hate questions like this one. Do you know why? Because I fear that the TEACHERS asking the question of their students are either IGNORANT of the subject matter they are supposed to be teaching or are asking a TRICK question of their students, which is almost always intellectually dishonest. Hopefully, it's just a poorly worded question by the poster of the question. Okay, I'll shut up and answer the question. A quantity of cold air can occupy a greater volume of hot air -- if there is more cold air than hot air!!!! If you've got two liters of cold air, that's a greater volume than one liter of hot air!!!!!! But what if you've got 0.1 kilogram of hot air and 0.1 kilogram of cold air? You've got the same amount of matter, right? They have the same mass: 0.1 kg. Will the hot and cold air occupy the same volume? NO!!! The hot air is less dense, which means it occupies MORE volume per unit mass than the cold air. So, if you have equal masses of hot and cold air, the hot air will have greater volume.
What else can I help you with?
Which has more sediment hot or cold water?
Normally Hot
Does water flow from hot to cold?
No, cold water is piped into the hot water tank and is heated by electricity or gas, it then flows out to the hot water taps.
Which would corrode more quickly a pipe with hot water or a pipe with cold water?
the pipe with the hot water will.]The piping with cold water as many hydronic systems are over 100 years old and the piping looks as new as the day it was installedAs long as thermo stress and velocity are taken into consideration hot water lines can last longer then their cold countter parts as cold piping becomes more brittle over the years
What is the difference between a Hot water shut off valve and cold water shut off valve?
the hot water valve shut off valve shuts off the hot water. The cold water valve shuts off the cold water. ;()
Can you use PVC for hot tap water?
NO. PVC is for cold water only, CPVC is for hot or cold. I say forget the CPVC and just use pex.
Why hot water is heavier than cold water?
Given an identical volume of both to begin with (say, one gallon hot water, and one gallon cold water) they will be identical in weight. However, cold water is more dense than hot water.
Does cold water weigh less than hot water?
No, cold water weighs more (for a given volume) than hot water. This is why there is a thermocline in bodies of water. But when water freezes, the solid form weighs even less (for a given volume), this is why ice floats.
Does hot air have more volume than cold air?
yes 1 mole hot air have more volume then cold air
Are molecules in hot water different then molecules in cold water?
If you have the same volume of both then there are in cold water more molecules.
How can use hot water more wisely?
Hot water can be used more wisely by installing a low volume shower head. Washing clothes with cold is also very helpful.
Why does cold water have more molecules than hot water?
You may want to frame this question in this manner, "Why does cubic unit of cold water have more molecules than same cubic unit of hot water" This is so because heat causes movement in molecules and malkes them move apart. Hence the hotter the water, the further apart the molecules. Therefore, cold water has more molecules than hot water of same unit.
Is sugar more soluble in hot water or cold water?
Hot.
Is statch more soluble in hot or cold water?
hot water
Why does cold water have greater mass to volume ratio than hot water?
molecules are less agitated and therefore more densely packed together
What differences are there when you use hot or cold water in a lava lamp?
hot water contains more energy than cold water. cold water causes the water molegules to vibrate more.
What floats more between cold water and hot water?
The density of cold water is greater than hot water so there will be more substances that will float in it.
Why does water go down in a cold place and hot water goes up in an airtight place?
Cold water is denser then hot water and weighs more so hot water will always stay on top of cold water no matter the pressure in the line or volume unless forced by flow hot water water will always be on top.
