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?
It takes 1 calorie to raise the temperature of 1 gram of water by 1 degree Celsius. Therefore, to raise the temperature of 1 gram of water by 5 degrees Celsius, it would require 5 calories.
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 greater - a 1 degree rise in the Celsius scale or a 1 degree rise in Fahrenheit scale?
A 1 degree rise in the Celsius scale is equivalent to a 1.8 degree rise in the Fahrenheit scale. Therefore, a 1 degree increase in Fahrenheit is greater than in Celsius.
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).

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.
What is the amount of cooling required to low the temperature of a substance through 1 degree Celsius?
The amount of cooling required to lower the temperature of a substance by one degree Celsius is known as the substance's specific heat capacity. It depends on the substance's properties and can be measured in joules per gram per degree Celsius (J/g°C) or in joules per kilogram per degree Celsius (J/kg°C).
