Hi!
1. The particles will speed up as they gain more kinetic energy from their surroundings and try to escape. They will collide with the balloon more and cause gas pressure which over time will cause the balloon to explode.
2. The particles will slow down
3. It has more density unlike water which expands when it’s frozen. Normally a liquid has more volume and less density when heated.
4. 10°C 50°F
5. 0°C 35°C/36°C ( trick question it’s not 10 degrees less Fahrenheit but Celsius for both)
6. The air particles slow down, losing their energy to the surroundings in an attempt to change state.
