How much energy would be required to change 24.7 g of ice to liquid water?
The energy required to change ice to liquid water is known as the heat of fusion. For ice to water, the heat of fusion is 334 J/g. Therefore, to change 24.7 g of ice to liquid water, the energy required would be 24.7 g * 334 J/g = 8259.8 J.
How much heat is required to raise the temperature of 0.25 kg of water from 20 Celsius to 30 Celsius?
The specific heat capacity of water is 4186 J/kg*C. To calculate the heat required, use the formula: heat = mass * specific heat capacity * change in temperature. Plugging in the values, the heat required to raise the temperature of 0.25 kg of water by 10 degrees Celsius is approximately 1046.5 Joules.
How much heat must be removed from steam to change it to a liquid?
The amount of heat that must be removed from steam to change it to a liquid is the latent heat of vaporization of water, which is approximately 2260 kJ/kg at atmospheric pressure. This is the amount of energy required for water to change from a gas to a liquid state at a constant temperature.
Is the amount of heat required to boil 1kg of water equal to the amount of heat required to melt 1kg of ice?
No, the amount of heat required to boil 1kg of water is much higher than the amount of heat required to melt 1kg of ice. Boiling water requires additional heat to overcome the latent heat of vaporization, while melting ice only requires heat to overcome the latent heat of fusion.
How much heat is required to convert 0.3 of ice at 0 to water at the same temperature?
The heat required to convert ice at 0°C to water at 0°C is known as the latent heat of fusion. For water, this value is 334 J/g. Therefore, to convert 0.3 g of ice to water at the same temperature, the heat required is 0.3 g * 334 J/g = 100.2 Joules.
How much energy would be required to change 24.7 g of ice to liquid water?
The energy required to change ice to liquid water is known as the heat of fusion. For ice to water, the heat of fusion is 334 J/g. Therefore, to change 24.7 g of ice to liquid water, the energy required would be 24.7 g * 334 J/g = 8259.8 J.
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

What is the measurement of how much heat energy is required for a substance to melt?
The measurement of how much heat energy is required for a substance to melt is called the heat of fusion. It is the amount of energy required to change a substance from a solid to a liquid at its melting point.
How much heat is lost when 2012 grams of stream at 400 K is changed into ice at 263 K?
To determine the heat lost, we need to calculate the heat required to cool the steam from 400 K to 273 K (its condensation point), then the heat required to change it from steam to liquid water, and finally the heat required to freeze the water into ice at 273 K. These steps involve the specific heat capacities of water and steam, latent heat of vaporization, and latent heat of fusion.
Is the amount of heat required to boil 1kg of water equal to the amount of heat required to melt 1kg of ice?
No, the amount of heat required to boil 1kg of water is much higher than the amount of heat required to melt 1kg of ice. Boiling water requires additional heat to overcome the latent heat of vaporization, while melting ice only requires heat to overcome the latent heat of fusion.
How much heat is required to convert 0.3 of ice at 0 to water at the same temperature?
The heat required to convert ice at 0°C to water at 0°C is known as the latent heat of fusion. For water, this value is 334 J/g. Therefore, to convert 0.3 g of ice to water at the same temperature, the heat required is 0.3 g * 334 J/g = 100.2 Joules.
How much heat does it take to warm 21.0g of pure water from 90.0C to 100.0C?
To calculate the heat required to warm the water, you need to use the formula Q = mcΔT, where Q is the heat, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature. First, you need to calculate the temperature change (ΔT = 100.0°C - 90.0°C = 10.0°C). The specific heat capacity of water is 4.184 J/g°C. Plugging these values into the formula gives you: Q = 21.0g * 4.184 J/g°C * 10.0°C. Calculate to find the heat required.
How much heat is required to change 0.2kg of ice at -5 degrees to water at 5 degrees?
Heat required for this transition is given as the the sum of three heatsheat required for heating the ice from -5 degree Celsius +latent heat(conversion of ice at zero degree to water at zero degrees)+heat required to heat the water from 0 to 5 degree CelsiusHeating of ice=m x s x delta T,where m is the mass ,s is the specific heat of ice=200x0.5x5=500calmelting of ice=mxlatent heat=200x80=16,000calHeating of water=m x s x delta T,where m is the mass ,s is the specific heat of water =200x1x5=1000calTotal heat required=500+16,000+1000=17,500 cal
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).
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.
