How much energy is needed to raise the maximum temperature of 10kg of water from 20 degrees Celsius to 80 degrees Celsius?
Wendelyn
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 much heat energy will be required to lower the temperature of 2.67kg of steam from 282 degrees Celsius to 105 degrees Celsius?
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 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.
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.
How do you convert calories to degrees Celsius?
You don't, because they measure different things. Temperature (degrees Celsius) describes how deep the heat is in something, whereas energy (calories) describes how much heat energy you put into it in order to make it that deep. -- I have a bucket of water on the table. -- I take a small cup, I dip a cup of water out of the bucket, and I place the cup on the table next to the bucket. -- The water in the bucket and the water in the cup both have the same temperature. -- I want to make the cup 10 degrees warmer, and I also want to make the bucket 10 degrees warmer. -- I'll need to add more calories of heat to the bucket, and fewer calories of heat to the cup, to raise both temperatures by the same number of degrees.
Is the temp of steam at 100 degrees celsius same as 100 degrees celsius water?
Leaving aside the effects of pressure, yes, the temperatures are the same. But the amount of heat (thermal energy) per gram, is much greater for the steam.
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
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 the temperature of 3 G of silver from 15 degrees Celsius to 20 degrees Celsius?
3.50 J
How is temperature is measured?
Temperature is usually measured with a thermometer which tells you how many degrees Celsius or Fahrenheit the temperature is (Fahrenheit is the American measure and Celsius is what everyone else uses)

The temperature at which no more energy can be removed from a substance?
The temperature at which no more energy can be removed from a substance is absolute zero, which is 0 Kelvins or -273.15 degrees Celsius.
How many joules of energy are required to raise the temperature of 74g of water from 20 degrees to 70 degrees celsius?

What does doubling the energy content do to temperature?
This will depend on what kind of temperature scale you intend to use.Degrees Celsius, Degrees Fahrenheit or Kelvin.Celsius:If we have a positive number, say 10 degrees Celsius, then we would get 20 degrees Celsius.If we have a negative number, say -10 degrees Celsius, then we get -20 degrees Celsius. It will simply be twice as cold.Fahrenheit:Exactly the same rules apply as for Celsius in the examples of Celsius.Kelvin:Kelvin is an absolute that is "only" dealing with positive numbers.double of 10 Kelvin is 20 Kelvin. Double again and we get 40 Kelvin. Easy as pie.Temperature indicate how much energy there is in an object or a mix of objects.When doubling the temperature in Celsius, we add to this energy.When doubling the temperature in Fahrenheit, we add to this energy, but not as much as we would in Celsius.When doubling the temperature in Kelvin, then we actually double the energy-content. Much more than when using either Celsius or Fahrenheit.Increased temperature mean increased speed of reactions.
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.
