A new beginning.

hello! haha, i had to create a new blog since i forgot my pass.
haha k, anw...

Q1. Why cant we wear gloves to press the lift buttons?
i cant find any answers online... but i think it has something to do with heat.


what i think is, like especially for those sensitive to touch lift button, in order for it to work, they will have to detect the heat from our fingers.. And when we're wearing gloves to press the lift buttons, heat cannot pass through the gloves, hence, they cannot detect the heat and it wont work.
please do correct me if im wrong.



Q2.Why do ice stick to your fingers?


Our skin has high moisture content and very appropriate to form the bond with the oxygen atoms and hydrogen atoms that are inside the ice facing outwards which causes them not to connect with the other molecules to form hydrogen bond. So when our finger meets with ice, they stick together.
