A sample of H2O with a mass of 46.0 grams has a temperature of -58.0 Celsius. how many joules of energy are necessary to heat the ice to 0 Celsius use 2.1 joules for the specific heat of ice?

If the sample is at 100 0C, at standard pressure, no supplementary heating is necessary.
==============================
A similar but more detailed take:
Water's latent heat of vaporization is listed as 2,260 kJ/kg = 2.26 J/gram
Since your sample of H2O is in equilibrium right now and sitting there with the uniform
temperature of 100°C, it's ready to vaporize the next time some energy is added,
no matter how little.
Let's say an additional 0.1 Joule comes along and is absorbed. Some little tiny
mass of water ... 0.1/2.26 gram in this example ... must change phase and turn
to vapor. There will be a small blurp in the beaker as the vapor rises, the
surface of the liquid will be disturbed, and anyone watching will report that
it has 'boiled'.
To change the phase of the entire 46.0 grams and turn it to vapor would require
46 x 2.26 = 103.96 Joules.

What is the specific heat of liquid water?
This is the necessary energy to raise the temperature of 1 gram with 1 kelvin.
How To calculate Specific Heat of A compound Such as NaOH?
Specific heat is the measure of energy it takes to raise a unit mass in temperature by one degree Celsius. When measuring a compound that is water soluble, heat it separately to a specific range, then use the liquid to calculate the amount of heat that was used.
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
If 4.2kj of energy will raise the temperature of 1kg of water by 1 degree Celsius 1g of fat contains 38.5kj of energywhat would the temperature of 1kg of water if 0.5 g of fat is burned?
The temperature of the water would be 4.58333 degrees Celsius higher.
Would substances with high specific heat capacity also have high temperatures?
Specific heat capacity is the amount of energy or heat required to raise the temperature of a unit mass of a substance by one kelvin. So if the specific heat capacity is high then you would require more energy or heat to raise its temperature. The specific heat capacity does not really have anything to do with how much you can increase an objects temperature. IT HAS TO DO WITH THE ENERGY NEEDED TO INCREASE THE TEMPERATURE.
What is the amount of energy needed to change the temp of a substance called?
The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius
How do you calculate the total heat required in kcal to take 70 grams of ice at -29.0 Celsius and convert it to steam at 106 Celsius?
heat energy required to raise the temperature of ice by 29 celsius =specific heat capacity of ice * temperature change *mass of ice + to change 1kg of ice at 0 celsius to water at 0 celsius =specific latent of fusion of ice*mass of water + heat energy required to raise the temperature of water by 106 celsius =specific heat capacity of water * temperature change *mass of ice + to change 1kg of water at 106 celsius to steam at 106 celsius =specific latent of fusion of ice*mass of steam
The specific heat of the material is?
specific heat content is calculated by the joules of energy required to change the temperature of one cubic centimeter of the material 1 degree Celsius.
What ocean temperature is necessary to provide the energy for hurricane information?
The temperature of the ocean must be 80 degrees or 26 celsius in order for a hurricane, typhoon or a cyclone form.
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!
What is specific heat capacity equation?
Quantity of Energy= mass x temperature change x specific heat capacity For example: Find the amount of energy needed to raise the temperature of 0.20 kg of lead by 15 degree Celsius if the specific heat capacity of lead is 0.90 J/g degree Celsius. Answer: J=200g x 15 degree Celsius x 0.90 J/g degree Celsius = 2700 J
What property of a material tells you how much energy it can store?
Specific heat capacity tells you how much stuff energy can store. specific heat capacity is the amount of energy needed to raise the temperature of 1kg of a substance by 1 degrees celsius. water has a specific heat capacity of 4200 J/kg degrees celsius.
What is specific heat capacity?
Is the amount of energy that is required to change the temperature of 1kg of a substance by 1 degree Celsius with no state change.
What is the amount of energy needed to raise the temperature of 1 gram of water 1 degree celsius?
The amount of heat necessary to raise 1 gram of a substance by 1 degree Celsius is known as?

90,000
How many kilojoules of energy are necessary to raise the temperature of 3 kilograms of cast iron from 30 degrees celsius to 120 degrees celsius?
I will use this formula. Some conversion will be required. ( I only know specific heat iron in J/gC ) q(Joules) = mass * specific heat * change in temperature Celsius 3 kilograms cast iron = 3000 grams q = (3000 g)(0.46 J/gC)(120 C - 30 C) = 124200 Joules (1 kilojoule/1000 joules) = 124.2 kilojoules of energy needed ===========================
