How many calories are required at 0 degree celsius to melt an ice cube with a mass of 25grams?
For water, the heat of fusion is 80 cal/g. So in other words, this is how many calories are needed to melt 1 gram of water that is frozen. Conversely, when you freeze 1 gram of water, you remove 80 calories of heat from it....
So, you multiply the calories needed to unfreeze a gram of water by the number of grams you have. In this case, 80 * 25 = 2000 Calories

What is the quantity of heat in joules or calories required to raise the temperature of 1 gram of a substance 1C?
The quantity of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius is defined as the specific heat capacity of that substance. It is measured in joules per gram degree Celsius (J/g°C) or in calories per gram degree Celsius (cal/g°C).
How many calories would it take to heat up Lake Michigan by 1 degree Celsius?
To calculate the calories required to heat up Lake Michigan by 1 degree Celsius, you would need to know the specific heat capacity of water (4.186 J/g°C) and the mass of water in Lake Michigan. The formula to calculate the energy required is: Energy = mass of water x specific heat capacity of water x change in temperature. This would give you the calories needed to heat up Lake Michigan by 1 degree Celsius.
How many calories are required to raise the temperature of 1 g of water by 5 degrees C?
1 calorie is the energy required to raise 1 gram of water by 1 degree C. So it would take 5 calories to raise it by 5 degrees C.
The amount of heat per unit mass required to raise the temperature by one degree Celsius is?
Specific heat capacity is the amount of heat energy required to raise the temperature of one unit mass of a substance by one degree Celsius.
What is relation calorie and joule?
Calorie and joule are both units of energy. One calorie is defined as the amount of energy required to raise the temperature of one gram of water by one degree Celsius, and it is equivalent to approximately 4.184 joules. Therefore, to convert calories to joules, you can multiply the number of calories by 4.184. Conversely, one joule is approximately 0.239 calories.
How were calories were made?
calories were never "made." they are simply the amount of energy required to raise the temperature one gram of water one degree celsius.
What is the quantity of heat in joules or calories required to raise the temperature of 1 gram of a substance 1C?
The quantity of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius is defined as the specific heat capacity of that substance. It is measured in joules per gram degree Celsius (J/g°C) or in calories per gram degree Celsius (cal/g°C).
Is temperature measured in calories?
No, temperature is not measured in calories. Temperature is typically measured in degrees Celsius (°C) or degrees Fahrenheit (°F), while calories are units of energy related to the amount of heat required to raise the temperature of one gram of water by one degree Celsius.
How much heat is required to raise the temperatureof 1500 g of water?
The amount of heat required depends on the desired temperature change. For example, to raise 1500 g of water by 1 degree Celsius, it would require 1500 calories (1 calorie per gram per degree Celsius).

What is the quantity of heat in joules or calories required to raise the temperature of 1 gram of a substance 1C.?
specific heat(; your welcome!
What is the differences between Calorie and kilo calorie?
A calorie is the unit of energy required to raise one gram of water 1 degree Celsius. A kilocalorie, or Calorie, is the equivalent of 1000 calories.
What is the number of calories needed to raise one gram of water by one degree Celsius?
1
How many calories are given up by one gram of 100 degree Celsius steam that condense to 100 degrees Celsius water?
540 cal
What is the amount of energy required to raise temperature of one gram of water by one Celsius degree is called?
The amount of energy required to raise the temperature of one gram of water by one Celsius degree is called the specific heat capacity of water. It is approximately 4.18 joules per gram per Celsius degree.
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.
