4.1858 joules of energy will raise the temperature of 1 g of water by 1oC.
Thus, 4.1858 * 955 * 80 = 319795.12 joules of energy is required to raise the temperature of 955 g of water by 1oC.

True or false a calorie is the amount of heat energy required to raise the temperature of 1 g of water 2 degrees C?
false its 1 degrees Celsius
What energy is required to melt 18.2g of water?
The necessary heat is 1,45 kcal.
What is the amount of heat required in joules to heat 82g of water from 24C to 66C?
Using the formula Q=mcΔT, the amount of heat energy required is (82g)(4.18J g-1 K-1)(42K) = 14400J.
How much energy is needed to boil water at 100 degrees?
The amount of energy to boil water depends on two things: the amount of water and the temperature of the water when you start.The more water water, the more energy it takes. The colder the water, the more energy it takes.Let say the water is at room temperature, or 20 °C. First, the water must be heated to 100 °C, which takes energy. The amount of energy is given by the specific heat of water, which is 4.186 Joule/gram °C. That means that requires 4.186 Joules of energy to heat 1 kilogram of water by 1 °C. So if you have 1 kilo grams of water at 20 °C, you have to add this much energy:= (4.18Joule/gram °C) (100g) (100 °C - 20 °C)= 334400 joules/°COf course, if you had more or less water, or it was colder or warmer, you would adjust this equation accordingly..
Why on heating a liquid to boiling point heat energy is converted to potential energy?
the heat is a form of energy...and heat is stored is the water...so heat energy become potential energy because heat is stored in water
How much heat energy in kilojoules is required to convert 41.0g of ice at -18.0 degrees C to water at 25.0 degrees C?
19.7 kJ
What energy unit is defined as the heat required to raise one kilogram of water by one degrees celsius?
I believe it is Calorie.
True or false a calorie is the amount of heat energy required to raise the temperature of 1 g of water 2 degrees C?
false its 1 degrees Celsius
What type of energy is required to change ice to water?
Heat
How does the mass of an object affect the energy required to heat it Also give example.?
The energy required to heat something is the product of the object's mass, its heat capacity, and how many degrees you want to raise the temperature. For example, if you fill your kettle with water, it takes longer to boil than if you only fill it partially.
If 30.86g of H2O is frozen (from liquid to solid) how much heat energy is required?
No heat (energy) is required to freeze water (from liquid to solid). Freezing RELEASES energy (heat), as it is an exothermic event. If you want to know how much energy is release, you need to know the heat of fusion for water, and then multiply that by the mass of water being frozen.
How many watts of heat to raise 55.32 gallons of water to 160 degrees?
A watt is a unit of power: what is required is probably the amount of energy - which is measured in joules.
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 much more heat needs to be added to water at 100 degrees centigrade in order to change it to steam?
Heat required to have such a change of state is called latent heat. If L J/kg is the latent heat per kg of water then for M kg of water we need M* L joule of heat energy
Where does the heat come from that turns into water vapor?
Any external heat source can provide the required energy.
How much heat energy is required to raise the temperature of 5 kilograms of cool from 20 degrees celto 220 degrees cel?
314j
What energy is required to melt 18.2g of water?
The necessary heat is 1,45 kcal.
