You mean how much heat energy will be lost/transferred as you are losing Joules here. All in steam, so a simple q problem and no change of state.
2.67 kg = 2670 grams
q = (2670 grams steam)(2.0 J/gC)(105 C - 282 C)
= - 9.45 X 105 Joules
-----------------------------------
This much heat energy must be lost to lower the temperature of the steam.

How much energy is needed to raise the maximum temperature of 10kg of water from 20 degrees Celsius to 80 degrees Celsius?
The energy required to raise the temperature 1 degree Celsius of 1 gram of water (1 mL) is 1 calorie (=4.18 J). So for 1 kg, 1Kcal (= 4180 J = 4.18 KJ) is required. To raise it 60 degrees, just multiply by 60 and for 10 kg multiply by 10 again. That would make 2.508 MJ (= 2508000 J) Now this is not completely accurate. The energy required to raise the temperature of water differs at 20 degrees from that at 60 degrees. The difference is small (~0.05 J or something like that) but still present.
How many Calories equals 350 degrees celsius?
Celsius is a unit of temperature, calorie is a unit of energy. Although temperature and energy are closely related they are not the same.calories required to heat 1kg of Alluminium in 350˚ = 910 × 350 = 318500J = 76 123.33 calories requiredcalories required to heat 1kg of Copper in 350˚ = 390 × 350 = 32 624.28 calories requiredcalories required to heat 0.5kg of Alluminium in 350˚ = (910 × 350)÷2 =159250J = 38061.66 calories requirednotice the difference between heating different materials, and heatingdifferent amounts of the same material makes difference in energyrequired
How many btu to raise the temperature of water from 60 to 120 degrees?
That's going to depend on how much water you're responsible for. Teacup at 60 degrees . . . very few BTU. Swimming pool at 60 degrees . . . many more BTU. It's also going to depend on whether you're talking about Celsius or Fahrenheit degrees. Fahrenheit degrees . . . fewer BTU. Celsius degrees . . . more BTU. (Also, the water will escape as you pass 100.) In general, one BTU is approximately the energy required to raise the temperature of 1 pound of water 1 degree Fahrenheit. You can take it from there, when you reach the job site and determine the exact scope of the work.
What is the BTU required to raise the temperature of 10 pounds of water from 50 degrees to 70 degrees?
200 BTU. I'm assuming your temperatures are in Fahrenheit, since all of your other measurements are in the Imperial system. A BTU is defined as the amount of energy required to raise the temperature of 1 pound water by 1 degree F, so the temperature is raised by 20 degrees, and 10 pounds of water: 20 x 10 = 200
How do you convert degrees Celsius to meters?
You do not. A degree Celsius is a measure of temperature or thermodynamic energy, whereas a metre is a measure of distance or length in 1-dimensional space. The two measure different things and, according to the basic rules of dimensional analysis, conversion from one to the other is not valid.
What term describes the amount of thermal energy that is required to raise the temperature of a substance by 1.0 degrees Celsius?
Specific heat capacity is the term that describes the amount of thermal energy required to raise the temperature of a substance by 1.0 degree Celsius.
How much energy would you use to raise temperature of kg of water by 2 degrees Celsius?
The amount of energy required to raise the temperature of 1 kg of water by 1 degree Celsius is approximately 4,186 Joules. Therefore, to raise the temperature by 2 degrees Celsius, you would need about 8,372 Joules of energy.
Is temperature measured in calories?
No, temperature is not measured in calories. Temperature is typically measured in degrees Celsius (°C) or degrees Fahrenheit (°F), while calories are units of energy related to the amount of heat required to raise the temperature of one gram of water by one degree Celsius.
Explain whether your body gains or loses thermal energy if your body temperature is 37 degrees Celsius and the temperature around you is 25 degrees Celsius?
25degres celsius has more thermal energy
What is substances specific heat?
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!
How much energy is required to raise the temperature of 0.2kg of aluminum for 15 degrees celsius to 18 degrees celsius?
The specific heat capacity of aluminum is 0.9 J/g°C. To calculate the energy required to raise the temperature of 0.2kg of aluminum by 3 degrees Celsius, you would use the formula: Energy = mass x specific heat capacity x temperature change. Substituting the values into the formula, Energy = 0.2kg x 0.9 J/g°C x 3°C = 0.54 Joules.
What temperature is absolute zero in degrees Celsius?
Absolute zero is -273.15 degrees Celsius. At this temperature, particles have minimum movement and energy.
How many joules does it take to raise temperature from 30 degrees Celsius to 45 degrees Celsius?
To raise the temperature of a substance, you need to calculate the heat energy using the specific heat capacity of the substance. Without knowing the specific heat capacity of the substance in question, it's not possible to determine the exact amount of energy required to raise the temperature from 30 to 45 degrees Celsius.
How much energy is required to raise the temperature of 0.2 kg of aluminum from 15 degrees celsius to 18 degrees celsius?
The specific heat capacity of aluminum is 900 J/kg°C. The change in temperature is 3°C. Using the formula Q = mcΔT, the energy required would be 0.2 kg * 900 J/kg°C * 3°C = 540 J. So, the energy required to raise the temperature is 540 Joules.
How much energy is required to raise 21kg of water by 2 degrees Celsius?
The specific heat capacity of water is 4.18 J/g°C. To calculate the energy required to raise 21 kg of water by 2 degrees Celsius, use the formula: Energy = mass x specific heat capacity x temperature change. Plugging in the values, the energy required is 21,084 Joules.
How much energy is required to raise the temperature of 3kg of iron from 20 degrees Celsius to 25 degrees Celsius?
The specific heat capacity of iron is 0.45 J/g°C. To raise the temperature of 3kg (3000g) of iron by 5 degrees Celsius, you would need: 3000g x 0.45 J/g°C x 5°C = 6750 Joules of energy.
True or false a calorie is the amount of heat energy required to raise the temperature of 1 g of water 2 degrees C?
True. A calorie is defined as the amount of heat energy needed to raise the temperature of 1 gram of water by 1 degree Celsius.
