Question

Give reasons for the following situtation :
a. The drink rises in the straw as we sip it​

Answer 1

Answer:

When we sip something with the help of a straw, it forces the liquid to rise up in the straw. The atmospheric pressure (which is higher than the vacuum) outside, thus, pushes the liquid into the low pressure straw. Thus the liquid reaches our mouth and we are able to drink.
