is heat independent of molecular collisions?Lets say I have a given amount of co2 gas in a 1L container, then?

Question

I place the same amount of gas in a one half liter container. When all other conditions are controlled for, shouldn't the temperature of the co2 gas in the second container be higher as more molecular collisions are occurring between paricles? And heat is "random motion of molecules" right? So when a gas is transferred to a smaller container, its temperature is raised, correct?

Answer 1

Yes, yes.

Temperature is a measure of molecular movement. The faster an objects’ molecules are moving the hotter it is.

When you freeze an item you are reducing the molecular movement inside of that item. If you were to be able to reduce to the temperature to absolute zero then all molecular movement would cease. This is an impossible condition, like a perpetual motion machine. The average temperature of deep space is 3-4 degrees C above absolute zero, and this is the coldest thing we know of or is possible.

When you moved your CO2 you reduced the size of the container, while keeping the pressure constant; that means it has to heat up. The molecules inside of the smaller container bump into each other more often thus creating more molecular movement; which translates to more heat.

Making liquid oxygen is very hard to do. We don’t have freezers that go down that low. The way to do it is to compress the gas, increasing the heat, and then removing that heat; cooling it down. Then the oxygen gas is allowed into a larger container. As it expands the temperature drops. Go through several cycles of this and you end up with a liquid. The example you cited is the exact opposite of this.

You are taking a gas and increasing the temperature of it by compressing it. The sun works by the power of gravity. The matter in the sun is compressed to an even tighter and tighter volume. If you keep the pressure up the heat increases; then the matter turns from a gas to a plasma. If you keep the pressure and temperature up then you can get fusion. Nuclear fusion happens because the sun is so dense that the matter is collapsed to a volume so small, which creates a pressure too large and increase the temperature. As the temperature increases it changes to a move violent form of matter (solid to liquid to gas to plasma). If you take a plasma of hydrogen and put it under even more pressure while keeping the temperature up then you create fusion. Two hydrogen atoms combine creating a hydrogen atom and releasing an extra neutron as radiation. This is an incredible violent and powerful reaction. The first way scientists created enough temperature and pressure to generate a fusion atom it took an atomic bomb.

Now day’s scientists are using lasers, and a magnetic containment field. If you take hydrogen and spin it in a circular magnetic field then you can increase the pressure and temperature. Do this enough and you get fusion; the fusion reactor. If the plasma touches anything it melts so the magnetic containment is critical. Without it you have failure. You can use the lasers to superheat the hydrogen and you can use the magnetic field to contain and constrict it. Do this enough and you can create fusion. Heavy hydrogen is used (deuterium) since it is more likely to enter a fusion reaction than normal hydrogen. Heavy hydrogen has an extra neutron in the nucleus. This extra neutron is then radiated as energy. Fusion is the most energetic reaction we know of.

Answer 2

No, heat is DEPENDENT on molecular motion.
In the smaller container they will be closer together and therefore will collide with each other, and with the container walls, more often resulting in higher temperature AND pressure. (To get the same amount in a smaller container, you'll actually be compressing the gas).

Answer 3

This is Charles' law : given an ideal gas its volume is directly proportional to the absolute temperature provided that the pressure stays constant.
V1 / T1 = V2 / T2
If T1 = 298 K
1 L / 298 = 0.5 L / T2
T2 = 149 K so the temperature is not raised.
If the pressure is not constant you can apply the combined law :
p1V1 / T1 = p2V2 / T2
Remember that T must be in K

Answer 4

it ought to. yet technically speaking your estimate continues to be too severe. you're able to think approximately that in case you weren't cycling to artwork, you will possibly nonetheless be generating CO2 emissions as you breathed. To wisely degree you're able to calculate the quantity of the CO2 output which you have from increasing on your greater exercising point once you're cycling. An estimate of 200 energy for that hour while you're walking around or one hundred energy while you're in simple terms sitting could be used. So calculate according to 4 hundred-500 energy, which equals .132-.106 g CO2. Yep, that's a dang low selection. reliable job. by using the way, i don't think of making calculations based on your production of CO2 whilst respiration would be suitable in international warming arguments in case you opt for to take action later. CO2 it extremely is breathed out is generally already accounted for in calculations concerning human emissions. i might p.c.. the bicycling for such distinctive different motives than to decrease the carbon impact on the ecosystem. additionally evaluate once you employ the scooter you're lowering your emission while in comparison with the Prius by using approximately 88%. you in simple terms get approximately yet another 11.5% by using bicycling. EDIT: I ws gazing your formulation and replaced into thinking in case you dropped to g once you meant kg. if so, then you extremely might use someplace between 106-132 g of CO2 (or one hundred sixty by using your estimate)
