What is the amount of energy required to raise the temperature of one gram of water by one degree celsius?
The small calorie, symbol cal (note the lower case c) is the energy required to raise the temperature of 1 gram of water by 1 degree Celsius at 1 atmosphere of pressure. The small calorie is a pre SI metric unit of energy. In SI terms it is equivalent to about 4.2 Joules of energy. The small calorie is also called the gram calorie. If the subject is physics, calorie refers to the gram calorie, the small calorie.The large Calorie (note the upper case C) is the energy required to raise the temperature of 1 kilogram of water by 1 degree Celsius at one atmosphere of pressure. When the subject is diet, such as food nutritional data, Calorie always means the large Calorie, the kilogram Calorie.The existence of these two different but related units with the same name is confusing and is an invitation to error. This is unfortunate, but the kilo Calorie is deeply embedded in nutritional literature, and the gram Calorie is embedded in early physics literature, so we are stuck with this situation.If you are doing physics, try to stay with SI units.1 joule is needed to raise the temperature of one gram of water by one degree Celcius.
What is the amount of cooling required to low the temperature of a substance through 1 degree Celsius?
To lower the temperature of 1 gram of water by 1 degree Celsius would be to remove 1 calorie.
What means that a large amount of energy is required to change the waters temperature?
Specific heat
What is the 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!
What is the quantity of heat energy required to raise the temperature of a unit mass of a substance?
If the substance is water, this is the kilocalorie (1000 calories). One calorie is the heat to raise one gram of water by 1 deg C. Other substances don't have the same specific heat capacity as water, so you have to correct for that, first find out the heat capacity (specific heat) for the substance you are dealing with.
What amount of heat is required to raise the temperature of one gram of water one degree Celsius?
I believe it is a calorie.One Calorie.
The amount of heat energy required to raise the temperature of one gram of water by one degrees celsius is?
4.184 joules. The is the specific heat or Cp of water is 4.184 J/mol.

Why do you use Calorie instead of calorie?
A Calorie with a capital "C" is 1,000 calories with a little 'c'. Nutritional guides on food products measure Calories. A calorie is the amount of energy required to raise the temperature of one gram of water one degree celsius. Normally when you eat food it gives you energy. If you eat 1 Calorie of food, it is enough energy to heat one kilogram (2.2 pounds) of water one degree celsius. Jus to maintain your body temperature, you need to eat a lot of Calories. On the other hand, if you eat a 10 gram ice cube, your body has to raise the temperature of the ice from 0 degrees celsius to 37 degrees celsius (body temperature). You will burn 370 calories in the process, but that is only .370 Calories.
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 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.
A calorie is the amount of energy needed to?
raise the temperature of the body by 1 Celsius
What is a calorie-?
answer:A calorie is a unit of measure used to describe the energy in food. It is defined as the amount of heat required to raise the temperature of 1kg of water 1 degree Celsius at 1 atmosphere pressure, or 4.184 Joules.Another AnswerA calorie is an obsolescent unit of measurement (cgsA system) used to measure energy; it is not simply used to measure the energy available in food, as implied by the original answer. It was defined as the amount of energy required to raise the temperature of one gram of water by one degree Celsius at standard atmospheric pressure.The original answer is not describing a calorie, but a kilocalorie which is 1000 calories.
Is thermal energy measured in Celsius?
No. Temperature is measured in degrees celsius. Thermal energy, which causes temperature change, is measured in calories or british thermal units. A calorie, not a food calorie, is the amount of heat necessary to raise 1 ml of water 1 degree celsius. 252 calories = 1 btu. 1 food calorie is actually equivalent to 1000 calories of heat.
What is the amount of heat needed to increase the temperature of a certain mass of a substance by 1 degree Celsius?
The heat capacity of a substance is the amount of heat required to raise the temperature of a defined amount of pure substances by one degree (Celsius or Kelvin). The calorie was defined so that the heat capacity of water was equal to one.
What is the amount of heat required to raise the temperature of a substance through ten degree Celsius?
One calorie is needed to heat 1 gram of water 1 degree Celsius
