∙ 10y agoSHC Water = 4.184 kJ/Kg/K so 4184 x 1 x (100-25) = 313800 Joules
assumption is that 1 liter of water is exactly 1 Kg

Water has a temp of 4.184 and copper has a temp of 0.387. Does it takes more heat to raise the temp of the copper molecule?
These are not temperature numbers but specific heat numbers. They mean that it takes 4.184 Joules and 0.387 Joules respectively to raise water and copper of one gram by one degree celsius. So, as you can see, it takes a lot more heat to raise the temperature of water than it does of copper. Water has a very high specific heat.
How much heat in joules is needed to raise the temperature of 4.0 L of water from 0 degrees Celsius to 70.0 degrees Celsius?
It takes 4.186 Joules to heat one gram of water by 1-degree Celsius. 4.186 * 4000 = 16,744 Joules to heat 4 kilos of water by 1-degree. 16,744 * 70 = 1,172,080 Joules. The above assumes that one litre of water weighs exactly 1 Kilogram.
How many joules of energy are required to raise the temperature of 150.0g of water from 274K to 318K?
4.184 J/g/K = 4.184 x 150 x (318-274) = 27614 Joules
How much energy would be needed to raise the temperature of 10 kilograms of water from 273 to 373 K?
10ml's of water is equal to 10cm3 of water. 10cm3 of water has a mass of 10g. The specific heat of water is 4.134 J/K. The change in temperature is 1 degree Kelvin. Use Q=mC∆T which means Heat= (Mass)(Specific Heat)(Change in Temperature) Q= (10)(4.134)(1) Q=(10)(4.134) Q=41.34 Joules
Why is a great deal of heat needed to raise the temperature of water by a given amount?
because it has a great heat capacity
How many joules of heat are needed to raise the temp of 2.83 kg of water from 38C to 46C?
0.0796
How many joules does it take to warm water by 1 degree?
It takes 4186 joules to raise the temperature of 1 kilogram of water by 1 degree Celsius. The mass does make a difference.
If 705g of water is heated 889J how much will its temperature increase?
It take 4.2 Joules to raise 1 gram of water by 1 degree Celsius. Each gram of water is heated by 1.26 Joules, creating an increase in temperature of .3 degrees Celsius.
Which would require a greater amount of heat water or iron?
To raise the temperature of both an equal amount, water would require more energy. In terms of the energy required to raise the temperature: iron = 0.45 joules / gram . kelvin water = 4.2 joules / gram . kelvin This is known as the specific heat capacity of a material
How many joules of energy are required to raise the temperature of 74g of water from 20 degrees to 70 degrees celsius?
15480.80
The number of kilojoules needed to raise the temperature of 32.0 g of water from 12.0 degree centigrade to 54.0 degree centigrade is?
q(Joules) = mass * specific heat * change in temperature q = 32.0 grams H2O * 4.180 J/gC *(54.0 C - 12.0 C) = 5617.92 Joules this is, of course 5.62 kilojoules
How much energy is required to heat 955 g of water from 20 degrees C to 100 degrees C?
4.1858 joules of energy will raise the temperature of 1 g of water by 1oC. Thus, 4.1858 * 955 * 80 = 319795.12 joules of energy is required to raise the temperature of 955 g of water by 1oC.
