This seems like a trick question. Without directly changing an object itself, its weight could be changed by significantly altering its altitude; objects weigh most at around sea level, but placing an object at the top of a tall mountain would weaken the pull of gravity on the object and thus its weight. If you put an object in orbit, it would be in freefall and have no weight at all.
Gas does not have a definite volume because it expands to fill the container it is in. It can easily change its volume when subjected to changes in pressure or temperature.
The volume decreases
That's because they are quite easily compressible. There are no forces holding the gas particles together. (apex)
because the volume of the gas is dependent upon the temperature and pressure. This is also important in the identification of the molecular mass of an unknown gaseous element.
According to Boyle's Law, when the volume of a gas is doubled with no change in Kelvin temperature, the pressure of the gas will be halved. This is because pressure and volume are inversely proportional in a gas at constant temperature.
Change the pressure and/or the temperature of the gas.
Because gas takes the shape of it's container, it can change volume quite easily. No matter what container you put it in, a gas takes that shape and volume.
I have no idea that's why i an askng you.
If the space in which the gas is inside doesn't change, the volume of gas doesn't change
Gas does not have a definite volume because it expands to fill the container it is in. It can easily change its volume when subjected to changes in pressure or temperature.
The volume decreases
Gas can change shape and volume. It does not have a fixed shape or volume and can expand to fit its container.
Temperature can be measured by determining the change in volume using gas thermometers. As a gas is heated, its volume increases due to the expansion of the gas molecules. By measuring this change in volume, the temperature of the gas can be calculated using the ideal gas law.
Increasing the temperature, increasing the pressure, or adding more gas molecules will increase the volume of gas.
No, changing the volume of a container filled with gas will not change the mass of the gas. The mass of the gas remains constant unless gas is added or removed from the container. Changes in volume only affect the pressure and density of the gas.
Volume ChangesThe volume of any solid, liquid, or gas will change with changes in temperature.
If you increase the volume of the container, and not the gas itself, then the pressure decreases. If you increase the volume of the gas, and not the container, then the pressure increases.
