However, it is reported that more current can be provided by increasing the optional energy (more joules) on the biphasic AED equipment to achieve successful defibrillation.[4] Considering the variable energy, when the first shock at 200 joule (default initial energy) fails, the energy level for...
How many joules to boil water?To boil one liter of water, we will need approximately 330 Joules of energy. If you boil ordinary tap water, it will take a bit more energy, around 360 Joules. The average formula is 4.186 Joule/Gram °C (J/g∙°C). It is even bigger than iron bec...
Because the calorie (cal), while not the SI unit of heat, is derived from metric units and is fundamental in a way: It isthe amount of heatneeded to raise one gram of water at room temperature by 1 K or 1 °C. (A 1-degree change on the Kelvin scale is identical to a 1-degree...
That's how many joules (the standard measurement of energy) you'd get from a kilogram of mass. In theory, if you could turn about seven billion hydrogen atoms completely to energy, you'd get about one joule (that's about as much energy as a 10-watt lightbulb consumes in a tenth of...

How many sig figs is 0.0? How much heat in Joules must be removed to freeze 25 kg of water at 0 degrees C to produce 25 kg of ice? The formula for converting Celsius temperatures to Fahrenheit temperatures is { F= \frac{9}{5}C + 32 } where F is the temperature in degrees Fahren...
Water has a very high specific heat capacity, which is the amount of heat per unit mass required to raise its temperature by one degree Celsius. The energy required to raise the temperature of water by one degree Celsius is 4.2 joules per gram. Water also has a high heat of vaporization,...
