How much energy is required to raise the temperature of 3 kg of iron from 20C to 25C?
1935 J
How much energy is required to raise the temperature of 3 kg of iron?
Q = 3 000 . 0,444 . ΔT (joules)ΔT is the difference of temperature.
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
Does liquid iron has less thermal energy or more thermal energy?
Iron naturally exists in solid state and heat is required for its liquifaction so liquid iron has high thermal energy.
How much energy is required to raise the temperature of 2kg of iron from 20 C to 23 C?
(Explanation): remember to convert the 2kg to grams, then multiply in this equation Q=(2000)(0.45)(3) to get Q=2700J
How much energy is required to raise the temperature of 0.2 kg of iron from 15 c to 18 c?
538J
How much energy is required to raise the temperature of 3 kg of iron from 20C to 25C?
1935 J
How much energy is required to raise the temperature of kg of iron from C to C?
The formula is: 0,108 x 3000 x (T1 -T2), in kilocalories.

How many kilojoules of energy are necessary to raise the temperature of 3 kilograms of cast iron from 30 degrees celsius to 120 degrees celsius?
I will use this formula. Some conversion will be required. ( I only know specific heat iron in J/gC ) q(Joules) = mass * specific heat * change in temperature Celsius 3 kilograms cast iron = 3000 grams q = (3000 g)(0.46 J/gC)(120 C - 30 C) = 124200 Joules (1 kilojoule/1000 joules) = 124.2 kilojoules of energy needed ===========================
Does liquid iron has less thermal energy or more thermal energy?
Iron naturally exists in solid state and heat is required for its liquifaction so liquid iron has high thermal energy.
If 1 gram of iron requires 0.11 calories to raise the temperature 1 degree Celsius what is iron's specific heat?
0.11cal/g degrees C
How many calories are required to raise the temperature of a 35.0g sample of iron from 25 C to 35 C?
38 cal
How much energy is required to raise the temperature of 2kg of iron from 20 C to 23 C?
(Explanation): remember to convert the 2kg to grams, then multiply in this equation Q=(2000)(0.45)(3) to get Q=2700J
5.10g sample of iron is heated form 36 degrees C to 75 degrees C the amount of energy is 89.5j the specific heat capacity of this sample of iron is?
The specific heat capacity of iron is 0,45 J/g.K.
How much heat energy is absorbed in 65 gram sample whose temperature changed from 45 to 80 degrees celsius?
That completely depends on the specific heat capacity of the substance of which the sample is composed, which you haven't identified. It will take a lot more heat energy to raise the temperature of 65 grams of water 35 degrees than it would take to do the same to 65 grams of iron or yogurt, e.g.
