Why does the temperature inside a balloon decrease when it is popped?
When a balloon is popped, the air inside is forced to expand rapidly, which results in a decrease in temperature due to the expansion cooling effect. This is because the air molecules gain kinetic energy as they rapidly move apart, causing a decrease in the average kinetic energy of the molecules, leading to a drop in temperature inside the balloon.

How do you make a homemade barometer?
To make a homemade barometer, you will need a glass jar, a balloon, a straw, a rubber band, and a ruler. Stretch the balloon over the mouth of the jar and secure it with a rubber band. Tape the straw to the center of the balloon. Use the ruler to measure changes in the height of the straw to determine changes in atmospheric pressure.
What forms of energy are needed to make water run out of a faucet?
To make water run out of a faucet, potential energy from the water tower or pump system provides the pressure needed. Additionally, electrical energy may be required to power the pump that delivers the water to the faucet.
What forms of energy are needed to make a water run out of a faucet?
Water pressure makes the water run out of the faucet. This pressure is provided by the pumps in a city water system, or in the case of a home on a well, by the home pressure tank. This pressure tank is fed by the well pump and also has air pressure in it. Generally the water fills a large balloon (called a bladder) inside the tank, the pump then stops until the pressure drops (when the tank is nearly empty) In most home systems this is about 15 -20 gallons between each pump cycle.
