How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
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 much energy does it take to melt ice?
Heat because Ice and water would thaw out and begin to heat up
Does an icebreg have more or less heat than a pan of boiling water?
A pan of boiling water has more heat energy than an iceberg. This is because the water in the pan is at a much higher temperature compared to the ice in the iceberg. Heat energy is directly related to temperature - the higher the temperature, the more heat energy an object has.
How many joules of energy are necessary to heat the steam from 100.0 degree c to 114.0 degree c?
To calculate the energy required to heat a substance, you can use the formula: Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature. You will need to know the specific heat capacity of steam to determine the energy required to heat it.

How much heat is needed to heat 100g of water from 10 to 95 degrees?
A calorie of energy (NOT to be confused with a Calorie, they are different so watch the caps) is the amount necessary to heat 1 gram of water 1oC, so 30 calories are needed to heat 30 g of water 1 degree. To heat it 70oC would take 2100 calories (or 2.1 Calories) of energy.

Why does water take so long to warm up?
The specific heat of water determines how much energy is needed to heat water.
How much heat energy is tranferred to hot water?
The amount of heat energy transferred to hot water depends on various factors such as the initial and final temperatures of the water, the mass of the water, and the specific heat capacity of water. The formula to calculate heat energy transferred is: Q = mcΔT, where Q is the heat energy, m is the mass of the water, c is the specific heat capacity of water, and ΔT is the change in temperature.

How much energy is necessary to raises 250 liters of water from 10 degrees C to 50 degrees C?
The necessary energy is 10 000 kcal.

A substance that can be burned to release heat energy?
Many substances can be burned to release heat energy, pretty much anything. However, water or ice is one that can not.

How much energy is generated from freezing 2.5g water?
The amount of energy generated from freezing 2.5g of water can be calculated using the specific heat capacity of water and the heat of fusion for water. The energy released would be equal to the heat of fusion of water (334 J/g) multiplied by the mass of water (2.5g). By multiplying these values, you can determine the total energy released during the freezing process.
How much energy is necessary to heat 1.0 kg of water from room temperature (20 and deg C) to its boiling point (Assume no energy loss.) (b) If electrical energy were used how much would it cost at?
The energy needed to heat 1.0 kg of water from 20°C to 100°C is 334 kJ (specific heat capacity of water is 4.18 kJ/kg°C). To calculate the cost, you would need to know the cost of electricity per kilowatt-hour. If, for example, the cost is $0.12 per kWh, the cost to heat this water would be around $0.04 (334 kJ = 0.093 kWh, and 0.093 kWh x $0.12/kWh = $0.011).
