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
What is the maximum cold things can be?
The maximum cold temperature that things can reach is absolute zero, which is 0 Kelvin or -273.15 degrees Celsius. At this temperature, particles stop moving, and all thermal energy is removed from the system.
What does -270 degrees Celsius mean?
-270 degrees Celsius is the equivalent of absolute zero, the lowest possible temperature at which molecular motion stops. At this temperature, atoms have minimal energy and there is no 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.
Heat is measured in Celsius degrees true or false?
False. Heat is measured in units of energy such as calories or joules, not in degrees Celsius. Temperature, on the other hand, is measured in degrees Celsius.
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.
Is heat energy measured in units of joules degrees Celsius and in degrees Fahrenheit?
Heat energy is typically measured in joules (J) or calories (cal). Degrees Celsius and degrees Fahrenheit are units of temperature, not energy.
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)
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.
What is the temperature at which molecular energy is at a minimum?
The temperature at which molecular energy is at a minimum is known as absolute zero, which is equivalent to 0 Kelvin or -273.15 degrees Celsius. At this temperature, molecular motion ceases, and particles have the least possible energy.
What happens to water molecules as the temperature of water drops below 4 degrees Celsius but before it reaches 0 degrees Celsius?
As the temperature drops below 4 degrees Celsius, water molecules start to move slower and come closer together due to reduced thermal energy. This causes water to expand slightly, unlike most substances that contract when cooled. This unique behavior leads to water reaching its maximum density at 4 degrees Celsius.
What temperature does water evaporate and what temperature does water freeze?
Water evaporates at any temperature above 0 degrees Celsius (32 degrees Fahrenheit), as long as there is enough energy to break the hydrogen bonds. Water freezes at 0 degrees Celsius (32 degrees Fahrenheit), when the energy of the water molecules reduces enough for them to form a crystalline structure.
