How many joules are required to raise 25 g of ice at 0C to steam at 100C?
Hotambekyusupgp8147
Q = [ mI ] [ h sub sf + CshW ( 100.0 C - 0.0 C ) + h sub fg ]
Q = [ 25 g ] [ 333.7 J /g + ( 4.184 J / g - C ) ( 100.0 C ) + 2257 J / g ]
Q = [ 25 g ] [ 3009.1 J / g ] = 75230 J <---------

How much energy is required to vaporize 2kg of water at 100c?
The latent heat for water to steam is 550 calories (2310 Joules) per gram. For 2 grammes, double these figures.
Which one of following systems has the highest entropy?
Steam at 105 c
How many joules are required for boiling 21.1g of water at 100C?
You need o know the initial temperature of water:Heat = specific heat x difference of temperature x mass of water
The average kinetic energy of water molecules is greatest in .?
Steam at 100C
Why steam at 100 degree c is more effective for heating purpose than water?
steam is more effective because the particles of steam have absorbed extra energy in the form of latent heat of vaporization apparent temp is 100c and actual temp is more than 100c whereas the actual temp of water is 100c
If the heat of vaporization for water is 2260 Jg how many kilojoules are required to convert 5.00 g of liquid water at 100C to steam at 100C?
5x2260, so 11,300 J or 11.3 KJ

When do water molecules have the most greatest amount of energy?
Steam at 100C
Steam for a kettle is what temperature?
Water boils into steam at 100C or 212F at sea-level pressure.
What is the usual temperature of steam?
Anything greater than or equal to 212F (100C). Superheated steam used in steam locomotives, steam turbines in power plants, etc. can be any temperature from 500F to 2000F depending on the design of the system.Note: if you can see the "steam" it is not steam. What you see are tiny droplets of liquid water that have condensed from the steam and is probably exactly at 212F (100C) because it is in thermal equilibrium with the invisible steam at the same temperature.
How do you heat water without stove or oven?
As you probably already know, water boils at 212F (100C). This only applies when at sea level with an atmospheric pressure of 14.7psia. To raise the boiling point all you need to do is raise the pressure. In a steam plant where steam is used to drive turbines, the water is pressurized by heating it in an enclosed system. As the water turns to steam, the steam has no where to escape and the pressure in the enclosed system begins to rise. As the pressure rises so does the boinling point. Some plants will raise the temperature to 500F which corresponds to a pressure of about 620psi.
Why steam at 100 degree c is more effective for heating purpose than water?
steam is more effective because the particles of steam have absorbed extra energy in the form of latent heat of vaporization apparent temp is 100c and actual temp is more than 100c whereas the actual temp of water is 100c
What temperature does water turns into steam is degrees Celsius?
It can be anywhere in between 60C and 100C (boiling point).
Does steam at 100C kill bacteria?
Water or steam at 100 degrees Celsius will kill some bacteria. Detergent or soap is needed to kill the ones that survive the hot temperatures.
