It decreases
It Freezes ! :P
When you leave a balloon in the freezer overnight, the air inside the balloon cools down and contracts, causing the balloon to shrink. The particles in the air inside the balloon lose kinetic energy and move more slowly, resulting in a decrease in pressure and volume inside the balloon.
it dies
When you fill a balloon with air, the air molecules displace the surrounding space inside the balloon, causing the balloon to expand and stretch. The pressure of the air inside the balloon exceeds the pressure outside, creating tension in the balloon material, which keeps it inflated.
To calculate the enthalpy change of formation from combustion, you can use Hess's law, which states that the total enthalpy change for a reaction is the sum of the enthalpy changes for individual steps. First, determine the enthalpy change for the combustion reaction using a calorimeter or from standard enthalpy values. Then, apply the equation: ΔH_f = ΔH_combustion + Σ(ΔH_f of products) - Σ(ΔH_f of reactants), where ΔH_f is the standard enthalpy of formation. This allows you to derive the enthalpy of formation for the desired compound based on its combustion data.
It decreases.
When the air rushes out of the balloon, it releases heat energy, which results in a decrease in enthalpy within the balloon. This process is known as an exothermic reaction, where energy is released to the surroundings.
The balloon will either float or pop
The balloon expands.
compression
When you leave a balloon in the freezer, the air inside it will cool and contract, causing the balloon to shrink in size. This happens because the volume of gases decreases when they are cooled, causing the balloon to deflate.
When you release a balloon with air in it, the air inside the balloon is pushed out, causing the balloon to fly through the air. This happens because the air being forced out creates a force in the opposite direction, propelling the balloon forward.
it sinks
It will shock your hair
A hot air balloon would not work on the moon.
It Freezes ! :P
which term describes what happens to a cold balloon when placed in a hot car
