If the temperature remains constant what will happen to the pressure of a gas if you decrease the volume of the container that holds the gas Explain?
The pressure of the gas would rise. Explain? OK, Blow up a balloon and tie the end. Decrease volume of the container (step on balloon). Balloon explodes (Pressure rose)
Ideal gas law to explain why a hot air balloon floats?
We know from the ideal gas laws that when you heat a gas under constant pressure, it will expand. (In a hot air balloon, the air that is heated is not in a rigid container, but in a balloon that expands with the expanding gas; the pressure it is under is only the atmospheric pressure.) The expanded gas will then have a lower density and will therefore be bouyant in air, and therefore able to lift a balloon.
Why do balloon pop in sharp objects?
the pressure has increased
Can you explain why an inflated balloon shoots off when air is released?
The air inside the balloon is at a higher pressure than atmospheric pressure so the gas molecules inside the balloon are closer together on average than gas molecules outside the balloon. This means that the repulsive forces between the gas molecules inside the balloon are greater than the repulsive forces between the gas molecules outside it. When the balloon is opened, the gas molecules in the open end at the border between the higher pressure interior and lower pressure exterior will experience a greater repulsive force from the gas molecules inside the balloon than the molecules on the outside. This means that they experience a net force pushing them out of the balloon. As these gas molecules are pushed out by the gas inside the balloon, they push back on it with an equal and opposite force (due to Newton's 3rd Law of Motion). This equal and opposite reaction force causes the gas in the balloon to be pushed in the opposite direction to the escaping gas, which in turn pushes the balloon. As more and more gas escapes, the reaction force on the balloon continues to accelerate it, making it shoot off, until enough gas has escaped for the pressure inside the balloon to have dropped to the same level as the pressure outside the balloon.
When you rub an air filles balloon with your dry hair and press it against the wall . Explain why?
The friction from rubbing the balloon against your hair charges the balloon up with static electricity.

A blown up balloon is carried up a high mountain will it get bigger or smaller explain why its volume changes?
As balloons increase in altitude, there is less atmospheric pressure pushing on it, so the result is that the balloon expands. The opposite is true, if you sink a balloon in water there is more pressure on the outside of the balloon so it shrinks.
How does the factors affect evaporation explain?
- vapours tension- temperature- pressure- area exposed to atmosphere
Explain why a helium weather balloon expands as it rises in the air Assume that the temperature remains constant?
When the helium balloon starts gaining height, the pressure decreases and as the gas molecules are very freely movable (higher than the normal). They move apart from each other in the mean while they make the balloon to expand. The decrease in atmospheric pressure relative to pressure inside the balloon causes it to expand.

Explain why a tire or balloon expands when air is added?
The air particles are closer together creating more pressure inside a ballon or tired and makes it expand
Why do balloon pop in sharp objects?
the pressure has increased

Explain the concept of air pressure in terms of mass of air above some level?
The pressure at any level in the atmosphere may be measured in terms of the total mass of the air above any point.
Can you explain what a balloon payment calculator is?
A Balloon Payment is a large payment due at the end of a mortgage or loan period. Therefore, a Balloon Payment Calculator will help you to predict what you will owe on your Balloon Payment.
