What'sΔG of ice melting at 0C and 100atm? Density ice = 0.9168g/cm3, water = 1.000g/cm3 Gibbs Free Energy: The potential workable energy resulting from a chemical reaction is usually referred to as Gibb's free energy. It takes into account the system's e...
For everyone on earth who has lived so far, Time has moved at fairly the same rate, hence the keeping of clocks and calendars. Time in Physics is a rather complex idea, so much that there are a number of compelling ideas about it and the nature of time is still a subject of interest...
Question: The density of mercury is {eq}\rm 13600 \ kg/m^3 {/eq} at 0 degree Celsius. What would be its density at 20 degree Celsius? {eq}\rm (\beta = 0.95 \times 10^{-3} (^{\circ}C)^{-1}) {/eq} Volume expansion...
Sudden changes in the ratio indicate changes in slant. Sudden changes in density without changes in the ratio indicate a drop-off. The theory is applied to outline drawing and to the fact that pictures provide two surfaces (the real surface of the picture and the depicted surface). The two...
Water (chemical formula of {eq}H_2O {/eq}) is one of the most common molecules encountered by all of us. Water molecules are polar molecules due to the dipole moment from the electronegative difference between Oxygen and Hydrogen atoms. Like other molecules, wat...
wi= density of ice × volume of ice per unit length wwis the force of wind per unit length ww= wind pressure per unit area × projected area per unit length So, the total weight of the conductor per unit length is The sag in the conductor is given by ...
As you can see in the chart, water only has an exact density of 1 g/cm3at 39.2°F or 4.0°C. Once you get below water's freezing point (32°F/0°C),the density of water decreases becauseice is less dense than water.This is why ice floats on top of water and, when you put ...
Question: What is the absolute temperature corresponding to 23.8 degrees Celsius? Absolute Temperature: The absolute temperature of an object is its temperature on a scale relative to a zero point defined by the Third Law of Thermodynamics. The unit of this scale is the Kelvin unit. A temperatur...
How to calculate the weight of a certain amount of water at room temperature? How much ice in grams would have to melt to lower the temperature of 352 mL of water from 25 degrees C to 0 degrees C? (Assume that the density of water is 1.0 g/mL.) ...
