Answer:
See below
Explanation:
Temperature is basically a measure of the average kinetic energy of the particles in the sample ....so as temp goes up, kinetic energy increases
<h2>
Answer:Volume of the container will decrease</h2>
Explanation:
Given that the gas is trapped,so the gas cant escape.
The number of moles of gas inside the container will remain constant.
The initial and final pressures are the same.
So,pressure can be taken as constant.
Charles law states that at constant temperature,volume of a system is directly proportional to the temperature of the system.
Since the temperature is lowered,volume also decreases.
This is false/ i know because i live in an urban area and it increases by human construction.
Answer:
Hydrogen
Explanation:
Balloons are filled with light gases in order to make them float. Helium and Hydrogen are both light gases.
Helium is quite a lot lighter than air: it's about an eighth of the density of air. Hydrogen is about a sixteenth the density of air, so it'll float in air and will in fact float upwards.
Hydrogen however is twice as heavy as helium, but that doesn't mean the amount of lift off of the balloon is twice as much. The amount of lift is determined by the difference in density with respect to air.
Hydrogen is calculated to be less dense than helium, that explains why hydrogen filled balloons would go up higher.
Helium filled balloons are used because of the safety implications. The problem is that hydrogen is explosive may have some health and safety implications! Helium is much more safe to use.
