How is a container filled with oxygen gas and hydrogen gas different from a container filled with water in its gaseous state?
The second container will have a higher temperature.
No, if you have a contained filled with hydrogen and oxygen gas you have separated hydrogen molecules (H2) and oxygen molecules (O2). In water the hydrogen and oxygen are bonded to each other in water molecules (H2O). However, if you apply enough heat to a mixture of hydrogen and oxygen gas the two will react and water will be the product.
The early dirigibles air ships such as the Hindenberg were filled with hydrogen but this was later changed to helium Why were they originally filled with hydrogen and why was the change made?
A graduated cylinder or other container filled with liquid or sand can be used to measure volume, by measuring the change or displacement in its volume. When submerged in a filled container, an object will displace its volume. When placed in a filled container, it will only displace its weight in liquid, and may float.
If I am right in interpreting the question as "Are balloons normally filled with hydrogen and oxygen?", then the answer would be no. Although they can be, as both substances are gases, the majority of balloon are filled with air, a mixture of nitrogen, oxygen, carbon dioxide and other gases. If you mean the balloons that float, they are filled with helium
Which of a hydrogen filled balloon air filled balloon and a carbon dioxide filled balloon will deflate the fastest and which is the slowest and explain your answer?
A hydrogen balloon will deflate the fastest because molecules of hydrogen are the smallest and thus will more easily slip through the latex of the balloon. The carbon dioxide-filled balloon will deflate the slowest because these molecules are the biggest, and thus will have more trouble escaping the tiny pores in the balloon.
if you have a closed bottle or can, etc. , of water and you heat it up to a high enough temperature, then pressure builds up, right? Well if the container is filled with water then the pressure will build up faster, causing the container to burst, but if the container is only filled maybe halfway, it will take a little longer for the pressure to build up enough to cause the container to burst.
