Why does a wire not simply cut a block of ice in two when it passes through the ice? A blanket keeps our body warm in winter, but the same blanket can protect ice from melting. Explain how. Explain why water boils at a lower temp at higher altitudes th...
At what temperature does water boil at the top of Mount Everest? What is the relationship between pressure and temperature with regard to boiling point? Is the boiling point of water or the higher temperature of the water that cooks...
The article describes an activity program for elementary students which aims to teach them about air pressure and temperature by providing an answer as to why it takes more time to boil potatoes at high altitudes.Robertson, BillScience & Children...
Explain why water boils at a lower temp at higher altitudes than lower altitudes. Why do vapor bubbles in a pot of boiling water increase in size as they rise in the water? Why does atmospheric pressure decrease more rapidly than linearly with altitude? Explain why food can be coo...
Explain why oil separates from water. Why does cold water hold more salt? Why does evaporation occur? Why does temperature difference increase the rate of heat transfer? Why are temperatures lower at higher altitudes? Why does sublimation occur in chemistry?
Why does water vapor condense at the dew point temperature? Why is the volume of an ice cube is greater compared to when it melts to form liquid water? Why does evaporation happen? Why are temperatures lower at higher altitudes? Why do ionic compounds dissolve in water? Why does an amorpho...
Explain why water boils at a lower temp at higher altitudes than lower altitudes. Why does a stream of water from a faucet become narrower as it falls? Why does a gas become hotter when compressed by a piston in a cylinder? Briefly explain why the boiling point of water reduces as alt...
Explain how these salts can be less soluble at higher temperatures. Why would benzene boil at 100 degrees C instead of 80 degrees C? Why is vapor pressure of solution lower than pure liquid? Why does the vapor pressure of water decrease when NaCl is added to it? Explain why ethane burn...
Why does the solubility of gases decrease with increased temperature? Why is melting a physical change? Why is cold air more dense? Why are temperatures lower at higher altitudes? Why is heat capacity different for different materials? Why does a change in temperature indicate a chemical reaction...
Why does decreasing the temperature of a liquid make it freeze? Why do solutes dissolve in solvents? Why does NH3(g) dissolve in liquid water? Explain. Why are temperatures lower at higher altitudes? Why does sugar increase the boiling point of water? Why does kinetic energy decrease in...
