Is 50 grams 96 degrees Celsius 148 meters or 259 liters a measurement of volume?
Liters measure volume. Grams are a measure of mass, degrees Celsius are a measure of temperature, and meters are a measure of length.
What are the masses in grams of a 0.5 kg glass bowl and a 0.5kg iron pan that have a temperature of 68 degrees F when placed in freezer?
1000
How many joules of heat energy must be supplied to 21 g of water to raise the temperature of the water from 24 to 95 degrees Celsius?
21 grams through 71 degrees is 21x71 calories.
What is the final temperature of the mixture if 100gram of water at 70temperature is added to 200gram of cold water at 10temperature and well stirred?
I'll assume here that by "70 temperature" you mean "70 degrees Celsius". Basically, you have to calculate the average temperature of all of the water in the mixture, which will be the final temperature once it's well stirred. The 200 grams of water at 10 degrees represent 2/3 of the total amount of water (300 grams), so thus, multiply 10 by 2/3 to determine their contribution to the final temperature. You will get 20/3. The 100 grams of water at 70 degrees represent 1/3 of the total amount of water, so multiply 70 by 1/3 to determine their contribution to the final temperature. You will get 70/3. When you add together the two temperatures you get 90/3, which is equal to 30. Therefore, the final temperature is 30 degrees Celsius.
Is Temperature the flow of energy from warm matter to cool matter?
No, certainly not.Temperature is a measure of the average kinetic energy of the particles in a body. The temperature of a thing is how strongly the little bits of that thing are shaking about. If they shake hard enough, meaning that the thing is hot enough, they shake the bits apart, so that the thing melts or evaporates.If I take something hot and put it against something cold, then the shaking of the molecules of the hot matter jostle the molecules of the cold matter, passing on some of their energy. To us that is a flow of heat energy from the hot matter to the cold.Get that straight! It is a flow of energy, not of temperature, and the temperature is not the flow!But, you say, suppose I take 10 grams of water at 95 degrees and put them against 10 grams of water at 35 degrees, I will get 20 grams at 65 degrees, right? How does that differ from a flow of temperature?Temperature does not flow; heat does. I chose that example carefully to make it look like a flow of temperature. Think of a different example: suppose that we put 10 grams of mercury at 95 degrees against 10 grams of water at 35 degrees; then we would get the whole lot at just about 37 degrees instead of 65 degrees, because it takes about 30 times as much heat to increase the temperature of one gram of water by one degree as it takes to heat one gram of mercury by one degree.Now, what happened to that "flow of temperature"?Get the picture?Heat will flow until the temperatures are the same all right, but the heat still is the only thing that flows.But, you say, isn't the temperature itself the flow?No, because if I have water at 95 degrees and I don't have it touching anything at a different temperature, then there is no flow of heat (or energy, if you like; same thing in our examples) and yet the temperature stays at 95. If the temperature were the flow, then zero flow would mean zero temperature, right? And do we get zero temperature? Not a bit of it; we get 95 degrees!Is this helping you get it straight? If not, ask again.
What would be the final temperature when 250 grams of water at 100 degrees celsius is mixed with 525 grams of water at 30 degrees celsius?
The temperature would be that of water's boilng point od 100 degrees
how many grams iron will absorb 900 joules of heat and only change temperature by .2 degrees?

If 75 grams of water at 30 degrees Celsius absorbs 900 calories what will be the new temperature?
105C
What is the total heat loss if you have 18 grams of aluminum and the temperature changes from 64 degrees Celsius to 48 degrees Celsius?
Approx 4974 Joules.
Is 50 grams 96 degrees Celsius 148 meters or 259 liters a measurement of volume?
Liters measure volume. Grams are a measure of mass, degrees Celsius are a measure of temperature, and meters are a measure of length.
Fifty grams of water cooled from 50 degrees to 10 degrees if the specific heat of wayer is 4.2 hoe much was released?
If fifty grams of water cooled from 50 degrees to 10 degrees, and the specific heat of water is 4.2, 135 kJ of heat was released.
Is gram used to measure the temperature in the metric system?
No, grams are unit of mass, not temperature. Temperature is measured in °C (degrees celsius) or for scientific work in 'K' K = °C + 273.15
What is the density of warm water cold water and ice?
Density of ice at 0 degrees Celsius is 916.8 grams per cubic centimeter or milliliter. The density of fresh water is dependant on the temperature: At 3.98 degrees Celsius the density is 0.999975 grams per milliliter. At 100 degrees Celsius the density is 0.958.35 grams per milliliter.
How many calories of heat would it take to raise the temperature of 256 grams of water from 20 degrees to 99 degrees?
A calorie is the amount of heat you need to raise the temperature of one gram of water by one degree Celsius. Assuming you are raising the temperature of the water from twenty degrees Celsius to ninety-nine degrees Celsius, it would take 20,000 calories. To calculate this, subtract 20 from 99. This is the amount of degrees you need to raise the temperature of the water by. Then multiply that number by 256, the amount of water in grams. You should get 20,244 calories. In significant digits, your answer should be 20,000 calories.
How do you increase the the temperature of 500 grams of water from 20 degrees Celsius to 100 degrees Celsius?
q(joules) = mass * specific heat * change in temperature q = (500 grams H2O)(4.180 J/goC)(100o C - 20o C) = 1.7 X 105 joules ================add this much heat energy to the water
