Boiling-point is the point of a pure liquid matter starts to evaporate and change into gaseous phase. It is where the set of conditions such as the pressure and temperature enough to do so. Boiling-point elevation, on the other hand, is the phenomenon of which the boiling point of a pure liquid matter is elevated because of the dissolved substances. A great example would be the boiling point of a distilled water (pure water) which is lesser than the boiling point of a sea water because of the dissolved salts. A pure water boils at 100°C at atmospheric pressure while a salt water boils at higher temperature than 100°C at the same pressure. Thus, the answer is D.
Answer:
Wind
Explanation:
It's impossible for them to travel in a wave.
Answer:
c. 157 KJ
Explanation:
Q= mC dT dT= 100°C(boiling point) - 25°C=75°C
Q= (500 g * 4.184 J/g °C * 75 °C)
Q= 156900 J= 157 KJ
