delta E = q + w
= 850 + (- 382) = 468

What does a balloon do when heated?
the heat makes the molecules inside the balloon travel faster, pushing outward on the balloon. This, the balloon expands when heated
Why does the volume of a balloon increase as the balloon is heated?
Because the gas inside expands with the heat
What happen to the balloon when heated?
It expands until the temperature is high enough to compromise the balloon's skin.
When the gas in a balloon is heated the balloon expands what are the correct signs of heat and work for this change?
+Q, +W
How does temperature affect the gas in a balloon?
Heat expands the gas (any gas) and makes the balloon rise.
What usually happen to a toy hellium filled balloon that rises high into the atmosphere?
It will usually burst. As it gets higher, outside air pressure is less, helium in balloon expands until balloon pops.
Why do most balloons burst as they ascend high altitude?
The internal pressure of the gasses inside a balloon remains constant while external air pressure decreases as the balloon ascends. As the balance between the two changes, the pressure inside becomes progressively greater than the pressure outside, so the balloon expands. If it expands beyond the ability of the balloon material to contain it, the balloon will burst.
What happens when you add heat to a balloon filled with air?
The balloon expands.
Why would heating a hot air balloon make the balloon rise?
Hot air expands. When it expands, it becomes less dense and rises.
Why does balloon fly?
The hot air inside the balloon expands, making the hot air balloon fly.
What happens to a balloon when the gas in it increases?
It expands.
What does a balloon do when heated?
the heat makes the molecules inside the balloon travel faster, pushing outward on the balloon. This, the balloon expands when heated
Why does the volume of a balloon increase as the balloon is heated?
Because the gas inside expands with the heat
What will happen to a balloon's volume if its heated?
The kinetic energy of the particles inside the balloon increase. This then expands the volume of the balloon.
When a balloon heats up and expands is it thermal energy?
When any state of matter is heated it expands.
What happen to the balloon when heated?
It expands until the temperature is high enough to compromise the balloon's skin.
Explanation of blowing up balloon with carbon dioxide?
As the gas is pushed into the balloon the internal pressure increases, to reduce this pressure the rubbery material expands to increase the volume and ultimately reduce the pressure. Once the balloon is filled with CO2 and the knot is tied the balloon will probably sink this is because CO2 is more dense than air.
