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.

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?

Does your body gain or lose thermal energy if your body temperature is 37 degrees Celsius and the temperature around you is 25 degrees Celsius?
You will lose thermal energy.Heat (energy) will always flow from warmer to cooler.
What measurment is measured in kelvins or degrees celsius?
Kelvin is a measure of temperature or thermodynamic energy, and is an absolute measure. Degrees Celsius are a used to measure temperature on a scale with an arbitrary zero.
How much energy is required to raise 21kg of water by 2 degrees Celsius?
21 Kg = 2100 grams to rise the temperature of this amount of water by 2 degrees Celsius you need 2*2100 = 4200 calories or 17572.8 Joules.
