Question

1) at waht temperature water has the maximum temperature

2) at what temperature water will boil in hill stations

3) is mercury denser or is copper denser

Answer 1

Ans1)Superheated water is liquid water under pressure at temperatures between the usual boiling point, 100 °C (212 °F) and the critical temperature, 374 °C (705 °F). Ans2)it will boil beloow 100degree CelsiusBecause at the higher altitude the atmospheric pressure is reduced. Boiling of any liquid occurs when the partial pressure of the vapour (in this case water vapour) exceeds the atmospheric pressure acting on the liquid. It's like the atmospheric pressure is trying to "hold down" the steam and force it to stay in the liquid. If the atmospheric pressure is lower (as at high altitude) there's less pressure to hold the steam in the liquid and so the water boils more easily - at a lower temperature. Ans3). Density of Copper Copper is classified as a metal. It occurs naturally as a solid. Copper is mined from the ground and is found within ores of other elements. The density of copper is 8.93 grams per cubic centimeter. Density of Mercury Mercury is also classified as a metal. In its natural state, however, it is a liquid. In nature, mercury is rarely found in pure form. Mercury's density is measured at approximately 13.53 grams per cubic centimeter.
