In this scenario, the transition temperature is known as the calorimetric ideal glass transition temperature T 0c. In this view, the glass transition is not merely a kinetic effect, i.e. merely the result of fast cooling of a melt, but there is an underlying thermodynamic basis for glass formation. The glass transition temperature:
Temperature vs time plots, showing the Mpemba Effect. The Mpemba effect is the observation that a liquid (typically water) that is initially hot can freeze faster than the same liquid which begins cold, under otherwise similar conditions. There is disagreement about its theoretical basis and the parameters required to produce the effect.
Values of the Biot number smaller than 0.1 imply that the heat conduction inside the body is much faster than the heat convection away from its surface, and temperature gradients are negligible inside of it. This can indicate the applicability (or inapplicability) of certain methods of solving transient heat transfer problems.
Fragility characterizes how rapidly the viscosity of a glass forming liquid approaches a very large value approximately 10 12 Pa s during cooling. At this viscosity, the liquid is "frozen" into a solid and the corresponding temperature is known as the glass transition temperature T g. Materials with a higher fragility have a more rapid increase ...
Once the air temperature hits 122 degrees, our bodies can no longer dissipate heat and our core temperature rises. But another study cites a much lower limit of 89.6 degrees—the temperature at ...
Cold water does not boil faster. Water boils when it reaches its boiling point of 212 degrees Fahrenheit, 100 degrees Celsius or 373 degrees Kelvin.
An ice surface in fresh water melts solely by free convection with a rate that depends linearly on the water temperature, T ∞, when T ∞ is less than 3.98 °C, and superlinearly when T ∞ is equal to or greater than 3.98 °C, with the rate being proportional to (T ∞ − 3.98 °C) α, with α = 5 / 3 for T ∞ much greater than 8 ...
Just like glaciers have carved the land, leaving behind features like valleys and boulder fields, geologists have suspected that ice shelves along the ocean could do the same to the seafloor.
