It takes 4.2 joules per gram of water to raise the temperature by one degree Celsius. The total number of joules is then 190.176 kilojoules.
The number of joules to raise one gram of water by one degree Celsius is 4.2 Joules. The total number of joules needed then is 95,088 joules.
The answer is approx. 4,2.106 joules.
The energy required to raise the temperature is 1570 joules.
q(Joules) = mass * specific heat * change in temperature q = (20 grams H2O)(4.180 J/gC)(40o C - 30o C) = 836 Joules needed ===============
Any number of joules, no matter how small, will raise the temperatureof the water. The total number required in order to accomplish the jobdepends on the final temperature you want to see. The higher that is,the more energy it will take to reach it.
It takes 4186 joules to raise the temperature of 1 kilogram of water by 1 degree Celsius. The mass does make a difference.
The amount of energy required to raise the temperature of 1 gram of pure water by 1 degree C varies as the temperature varies but its average value is 4.184 Joules. So, to raise the temp of 2.8 kg = 2800 grams of water by 8 deg C = 4.184*2800*8 = 93,721.6 Joules or 93.7 kJ.
approximately 4200 Joules.
The amount of heat required to raise the temperature of water by 1 degree Celsius about 4.19 joules
It is 4200 Joules
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.
Either of two units of heat energy.The energy needed to raise the temperature of 1 gram of water through 1 °C (now usually defined as 4.1868 joules).
4.184 joules are neede to change 1g of water 1ºC, so it would take 4184 joules to raise the temp of 1 kilogram (4.184 kJ).
Well, it takes 4.184 joules to change 1g of water 1ºC, so it would take 4184 joules to raise the temp of 1 kilogram.
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.
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.
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
