q = m x C x ΔT
q = amount of heat energy gained or lost by substance in Joules
m = mass of sample in grams = 20g
C = heat capacity (J/g•oC) = 4.184 J/g•oC
Tf = final temperature = 55 oC
Ti = initial temperature = 5 oC
ΔT = (Tf - Ti) = (55 oC - 5 oC) = 50 oC
q = 20g x 4.184J/g•oC x 50 oC = 4184 Joules
Nominally 700,000 calories, or about 2,928,800 joules.
(That's a lot ! It's enough energy to lift a ton of gravel
more than 1,000 feet straight up off the ground.)
The heat capacity of water is 4184 J/kg/deg, so to raise 0.25 kg by 10 degrees (20-30 deg C), it would take (4184 J/kg/deg)(0.25 kg)(10 deg) = 10,460 J = 10.46 kJ = 10. kJ (2 sig figs)
The necessary heat is 2,5 kcal.
Approx 10.4 kilojoules.
The necessary heat is 9,42 kJ.
Heat capacity is the amount of heat energy required to raise the temperature of a unit mass of a material one degree.
The amount of energy required to raise 1 kg of a substance by 1 degree Celsius is called the "Specific Heat Capacity," or just specific heat, of a substance. This is an intensive property of the particular substance.
The amount of energy it takes to change the temperature of a substance by a certain amount. How much energy it takes to heat a substance ~APEX
This is due to the difference in the specific heat capacity of water and land. Water has a very high specific heat capacity. So the amount of heat required to raise its temperature is very high. That is why land heats up faster than water.
Well if it any substance such as water or steel it called the objects specific heat waters is 4180 (joules/( kilogram•Kelvin)specific heatIt is not the heat of a substance. The specific heat, Cp, is the energy required to raise the temperature of a gram of the material one degree Celsius at a constant pressure.
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.
The amount of heat a substance can hold.
Heat capacity is the amount of heat energy required to raise the temperature of a unit mass of a material one degree.
A measure of the heat required to raise the temperature of a substance
1 kilocalorie
How much heat energy is required to raise the temperature of 0.358 of copper from 23.0 to 60.0 ? The specific heat of copper is 0.0920
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
True.
The amount of heat required to raise the temperature of 1 gram of a body through 1oC.
The number of calories required will depend on the mass of water which is to be heated.
Heat required to raise the temperature of 1 Kg. of Pure water is called a Calorie or otherwise heat released on condensation of 1 Kg of pure water when it is condensed by 1 C is also a Calorie. Again if 1 pound pure water's temperature is raised by 1 F, the quantity of heat is 1 BTU (British Thermal Unit)
