How many joules of energy are needed to heat 25.0 grams of steam from 100.0 degrees Celsius to 29.25 degrees Celsius?
Use this formula.
q(in Joules) = Mass * specific heat * change in temperature
I will use specific heat of water at 25 C. You can look up specific heat of steam. You say " heat to " so I assume you have final and initial heat backwards.
q = 25.0 grams H2O * 4.180 J/gC * (100.0 C - 29.25 C )
q = 7393 Joules

8.200 J
How much energy is needed to melt g of ice at 0 Celsius?
To melt 1 gram of ice at 0°C, it requires 334 joules of energy. So for g grams of ice, the energy needed would be g multiplied by 334 joules.
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 ===========================
How much heat energy is needed to convert 50 kg of water at 80 degrees Celsius to steam at 100 degrees Celsius?
539 calories per gram for heat of vaporization plus 1 cal/gram/degree C 100 degrees C - 80 degrees C = 20 degrees C (539 calories + 20 calories) X 50 kg X 1000 gm/kg = 27950000 cal = 27,950 kcal
How much energy is needed to increase the temperature of a kilogram of water 5 degrees?
The specific heat capacity of water is 4.186 J/g°C. Since there are 1000 grams in a kilogram, it would require 20,930 Joules of energy to increase the temperature of a kilogram of water by 5 degrees Celsius.
What is an amount of energy needed to raise kg of a subsyance1c?
The amount of energy needed to raise the temperature of a substance is calculated using the formula ( Q = mc\Delta T ), where ( Q ) is the heat energy (in joules), ( m ) is the mass of the substance (in kilograms), ( c ) is the specific heat capacity (in joules per kilogram per degree Celsius), and ( \Delta T ) is the change in temperature (in degrees Celsius). This formula helps determine how much energy is required to achieve a desired temperature increase for a given mass of a substance.
How many joules are needed to change the temperature of 1 gram of water by 1C?
It takes 4.184 joules of energy to change the temperature of 1 gram of water by 1 degree Celsius.
How many calories are needed to raise the temp of 8.1 g of water 20 degrees Celsius?
The specific heat capacity of water is 4.18 J/g°C, which means it takes 4.18 Joules of energy to raise 1 gram of water by 1 degree Celsius. To raise the temperature of 8.1 g of water by 20 degrees Celsius, you would need 8.1 g * 20°C * 4.18 J/g°C = 676.56 Joules of energy.
