WebFeb 13, 2024 · Water has a specific heat capacity of 4182 J/kg°C. Because water is such an important and common substance, we even have a special way to identify the amount of energy it takes to raise one gram of water by one degree Celsius—a Calorie. This is different from the kind of calorie we talk about in food. WebThis value for Cp is actually quite large. This (1 cal/g.deg) is the specific heat of the water as a liquid or specific heat capacity of liquid water. One calorie= 4.184 joules; 1 joule= 1 kg (m)2(s)-2 = 0.239005736 calorie. …
WebSep 26, 2012 · To heat the same water volume in half the time (30 minutes) would need twice the heating power, ie, 7kW. Converesely, if we only use half the heating power, 1.75kW, it will take twice as long to heat up to desired temperature, ie, 2 hours. If we only have a 1kW element available, we will expect a heat up time in excess of 3 hours. WebA heating curve shows that it takes a 60 W heater 30 minutes to boil a sample of water.
