Calculate the internal energy of the system if a balloon is heated by adding 850 Joules of heat and it expands doing 382 Joules of work on the atmosphere?

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

The internal energy change of the system can be calculated by subtracting the work done by the system from the heat added to the system. In this case, the internal energy change is ΔU = Q - W = 850 J - 382 J = 468 J. Therefore, the internal energy of the system increases by 468 Joules.

What does a balloon do when heated?
When heated, the air inside a balloon expands and causes the balloon to inflate. If it gets too hot, the balloon can burst due to the pressure buildup.
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
Why does a partially inflated balloon expand as it rises?
The pressure in the balloon stays the same, but the pressure outside drops as the altitude increases. And as the outside pressure drops, the balloon expands.
What happens when a balloon is exsposed to heat?
When a balloon is exposed to heat, the air inside the balloon expands and the molecules move faster, causing the balloon to inflate. If the heat is excessive, the balloon may burst due to the increased pressure inside.
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.
What does a balloon do when heated?
When heated, the air inside a balloon expands and causes the balloon to inflate. If it gets too hot, the balloon can burst due to the pressure buildup.
Why would heating a hot air balloon make the balloon rise?
Hot air expands. When it expands, it becomes less dense and rises.
Does a Weather balloon change size?
Yes, a weather balloon expands as it rises through the atmosphere due to the decreasing air pressure. Once it reaches a certain altitude, the balloon will have expanded as much as it can and eventually burst.
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 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.
When there is no friction in space then how will blowed balloon expands?
The balloon will expand due to the pressure in its inside. This has nothing to do with friction.
