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 are required to boil one liter of water?
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.
How much energy would you use to raise temperature of kg of water by 2 degrees Celsius?
9.6 MJ
How does the temperature of 33.0 of graphite change when it absorbs 350 J of thermal energy?
shc of graphite = 710 j - kg - k > 350 joules would raise 1 kg by (350 / 710) 0.49295 deg kelvin, so would raise temp. of 33 kg by 0.493 / 33 = 0.014938 kelvin
How many joules of energy are necessary to heat sample of water with a mass of 46.0 grams from 0.0 to 100 C?
Assuming the water is liquid, the specific heat is about 4.186 joule/gram·°C, so to heat 46 grams of water would take about 192.556 joules/°C. The specific heat of ice is about 2.100 Joules/g·°C so heating 46 g of frozen water would take about 96.6 joules/°C. The specific heat of steam is about 2.020 Joules/g·°C so heating 46 g of water vapor would take about 92.2 joules/°C.

How many calories required to raise temperature of 1 liter of water 1 degree centigrade?
Well, let's see. Water at room temperature has a heat capacity of 4.18 J/g-C, and water also has a density of 1g/mL. If there's one litre of water, there's 1000 g of water. If the change in temperature is 1 C, and there are 1000 g of water, and specific heat capacity's 4.18... Q = mcT Q = (1000g)(4.18J/g-C)(1 C) Q = 4180 J So you need 4180 J of heat. *************************************** The definition of one calorie is as stated in the question. One calorie is equivalent to 4.18 Joules. Not sure where the maths went wrong but just so you know.
What is an amount of water whose temperature would change by 15 degrees Celsius when it absorbs 2646 joules of heat energy?
The amount of water whose temperature would change by 15 degrees Celsius when it absorbs 2646 joules of heat energy is 42,2g H2O.
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
Which one of the following materials would take the longest to raise its temperature?
The answer is WATER!
What would make water turn from a liquid to a gas?
You don't decrease the temperature, you raise the water's boiling point, or increase the water's temperature......
Which one of the following materials would take the longest to raise the temperature water basalt iron or lead?
water
How much heat is in fresh water?
It would depend on the temperature of the water, or average kinetic energy. (KE) However, what you may be looking for is how much heat is needed to raise the KE, or temperature, of water. 4.184 kilojoules per gram is the heat required to raise the temperature of water 1 degree Celsius.
How much heat energy is required to raise the temperature of 15 g of water 25 degrees Celsius?
6480 calories8LBs X 15 gallons x 54 DEGREES = 6480 CALORIES
How many joules are necessary to raise the temperature of 53.5 grams of water from 16.5 degrees celsius to 70.1 degrees celsius?
Energy is actually given off in the lowering of temperature. Use the equation Q = mc(change in T). In this case, m = 2.9, c = 4.179 J, and change in T = -12.1 degree C. Now solve for Q, the heat energy. This exothermic process gives off approximately 146.6 J of heat.
If 4.2kj of energy will raise the temperature of 1kg of water by 1 degree Celsius 1g of fat contains 38.5kj of energywhat would the temperature of 1kg of water if 0.5 g of fat is burned?
The temperature of the water would be 4.58333 degrees Celsius higher.
