If there are more people then human emissions are higher than previously.
Does helium have a weight ?
Yes. All matter has mass.
Not practically no. Weight involves gravity, which is pretty constant as long as you remain on the planet. Are you planning a trip away?
Not really. Matter has an unchanging mass which results in a varying force (weight) depending on the strength of gravity where the mass is located.
Equally, practically, helium gas has no force acting towards centre of earth (weight)
Sorry you have lost me there, clouds for instance have a constantly changing mass but are never referred to by weight.
Yes it does - the helium is floating up to the top of the atmosphere because it's lighter than the air. But the helium still has a mass/weight and is attracted to the earth and vice versa. Engineering toolbox says it has a density of 1 to 3 N/m^3, depending on temperature. N being newtons, the unit for weight.
OK - that doesn't alter what I said. Kilograms is a unit of mass, Newtons a measure of force. But on/near earth the conversion is very nearly identical in all locations. 1 kg = 9.81 Newtons. Mass is technically correct which is why scientists and engineers differentiate but there's no real practical difference when on earth.
Getting way to complicated for me now.
Remember that old joke?
I still cant understand how a 1000 litres of Diesel which weighs less than a tonne can be responsible for 2639 kgs of CO2, what would even be the volume of 2639 kgs of CO2 ?
No idea. But I do know one cubic meter of water is one metric tonne and diesel is over 100kg less.
The oxygen in the carbon dioxide is additionally taken from the atmosphere when the hydrocarbon (diesel) is burnt.
The average diesel molecule is C12H23 (ranging from C10H20 to C15H28), so carbon atoms makes up 90% of the weight of diesel. When combined with two atoms of oxygen, which have atomic masses of 16 vs 12 for carbon, then you get:
Implying guilt of avoiding fact by the effort they put into emphasising alternative lack of facts?
Bet there’s no word of the sugar loading in Oatly compared to milk.
