Hi, Can somebody help me with this question please? In humid air with a water content of 3 g / (kg dry air), liquid water is injected at a temperature of 30 ° C, after which the air temperature becomes 18 ° C and its relative humidity 50%. The total pressure is constant 1.013 bar and the mass of the dry air is 60 kg. Calculate: a) the amount of water injected; b )the air temperature before water is injected

(This video has Subtitles) In this video i try to make an approachable explanation of what is sound. Because is something so fundamental in our lifes, deserves to be understanded in physical terms but don't worry, this is a simplified version. First is explained how sound is a vibration and a wave, then is approached a very important property of sound, Frequency.I also talk about the speed of sound and how it changes with the medium in wich it propagates.In the end i mention some cool applications of sound like breaking glasses, visualizing sound and levitating small objects.

The Bernoulli 's principle is explained in this video, it's used in the most diverse range of applications ,from the simple spray mechanism of perfume to the lift in an airplane's wings . In this video both the Bernoulli 's principle and equation are explained , this is made without using much technical terms to make the video accessible to any curious out there . The purpose of my channel is to make physics fun and enjoyable , if you like to learn new stuff , visit my channel: https://www.youtube.com/channel/UC2avWDLN1EI3r1RZ_dlSxCw Facebook page : https://www.faceboo
