1- Balloons inflate when in warm/hot water, particles within the bottle gain kinetic energy from the surrounding water due to temperature gradient between the two. Excited particles vibrate more vigorously leading to the pressure of the gas increasing via collisions with the container wall. pressure is directly proportional to volume for a fixed amount of gas thus the internal volume of the balloon increases as the balloon expands.

Possibly reflecting how certain construction materials may expand and contract in different weather conditions.]]> 2016-09-27 10:42:04 UTC https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126604020 https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126604588 2016-09-27 10:45:05 UTC https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126604588 https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126604906 2016-09-27 10:46:40 UTC https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126604906 https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126605718 2016-09-27 10:51:03 UTC https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126605718 https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126605854 2016-09-27 10:51:46 UTC https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126605854 https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126605859 2016-09-27 10:51:48 UTC https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126605859 https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126605866 2016-09-27 10:51:50 UTC https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126605866 https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126606038 2016-09-27 10:52:38 UTC https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126606038 https://padlet.com/j_xiao_arch/ys1v749wo4fj/wish/126606251 I can blow balloon me
