Greenhouse gases are typically measured in terms of concentration (parts per million or ppm) rather than weight. This is done by capturing a sample of air and determining the proportion of greenhouse gases present. The concentration of greenhouse gases can then be used to calculate the total weight of these gases in the sample air volume.
When baking soda and vinegar are combined they will weigh less than when they were seperated.
something lighter than water
They are not really lighter, they only seem lighter. Objects weigh the same in water as in air, but in the water, there is an additional force, of the water pushing the object up.
Much lighter. If you weighed 180 pounds on earth you would weigh 68.4 pounds on Mercury.
No. Helium is nearly 100 times lighter than petrol or gasoline.
1000 grammes = 1KG, so a gramme is 1000 times lighter than a 1KG
weight and mass
Boars weigh around 1000 to 1200 lbs. Females (sows) are typically 30 per cent lighter than males (boars).
Your weight depends on the gravity, and Mars, being a smaller/lighter planet has less gravitational pull than the earth.
due to their height, they weigh lighter than humans their age. but not most of the girls actually revealed their weight except for cream, julie-su, etc.
If it's *ordinary* rock, yes. But some volcanic rock, like pumice, can be lighter than water, so... 55 barrels of pumice might be lighter.
