the information given is incomplete to tell the heat gained by water it also requires the amount of water taken and whether the temp has decreases or increased

How long do you heat water to get 98.6 degrees?
depends on the amount of water
) The temperature of a sample of water changes from 10 and degC to 20 and degC when the water absorbs 100 calories of heat. What is the mass of the sample?
one calorie of heat is able to raise one gram of water one degree Celsius so 400 calories could raise 1g of water 400 degrees, so it would raise the 80g by(400/80) 5 degrees Celsius plus the initial temp of 10 degrees, the 80g of water would have a final temp of 15 degrees Celsius
What is the heat that is released when water condenses and changes to liquid form?
The latent heat of vaporisation.
Would a rock fall faster in water or air?
Yep, water has a high heat capacity which means it absorbs a lot of heat before it changes temperature and once absorbed, it holds onto it. You can't say the same for rocks or especially sand.
When heat is taken away from water it changes from a liquid to what?
Water changes to a solid, ice, when heat is taken away from it. You can think of putting water into the freezer. Since the freezer is cold, heat flows out of the water making it become ice cubes.
When water at 0.c freezes is heat lost or gained?
As heat is a form of energy, it isn't lost or gained, it's just converted into another form of energy.
A calorimeter contains 0.750 kilogram of liquid water at 17.0 degrees C. A 0.0580 kilogram block of copper at 98.0 degrees C is placed in the water. What is the final temperature of the system?
You need to know the specific heat for copper. Then use q = mc∆T for copper and water. Heat lost by the copper MUST equal heat gained by the water. You can then solve for T2 of the water.
Is the heat intensity of water at 100 degrees celsius the same as the heat intensity of water 212 degrees Fahrenheit?
100 degrees celsius are equal to 212 degrees fahrenheit.
Why heat is needed to boil water?
Because heat changes the temperature of the water
How are the amount of heat transferred and the changes in temperature of water related?
Hi, heat transferred = mass x specific heat capacity x rise/fall in temperature If heat is lost then fall in temperature If heat is gained then rise in temperature. More the transfer then greater the difference in temperature.
A 34.44-g sample of metal is heated to 98.6 degrees Celsius in a hot water bath until thermal equilibrium is reached What is the specific heat of the metal?
Heat lost by the metal = heat gained by the water. Heat gained by the water = 50.0 g x 4.184 J/g K x (28.3-22.2) = 1276 J Heat lost by metal = 1276 J = 34.44 g x Sp Heat x (98.6 - 28.3) Specific Heat = 1276 J / 2421 g K = 0.527 J/g K
When enough heat energy is gained by liquid water the liquid water can?
molecule
What temperature do you use to heat water?
Water boils at 100 degrees Celsius or 212 degrees Fahrenheit.
What happens to water as it changes from a liquid to a solid?
As water changes from a liquid to a solid, heat is released. The heat of fusion of water is 79.72 cal/g or 333.55 J/g.
Why the heat capacity of water more than ice?
Water can hold more heat than ice before it changes states. For example, when you add heat to ice, it changes to water almost immediately. When you add heat to water it takes more to turn it into steam.
What is the name of heat energy that changes ice into water and water into steam?
Latent heat is the measurement of energy needed to change the state of a substance at its melting point or boiling point. The latent heat of fusion of water is the amount of energy needed to change a fixed amount of water from a solid to liquid at 0 degrees C. this works out to be more than 800KJ of heat energy. The latent heat of vaporization of water is the amount of energy needed to change a fixed amount of water from a liquid to a gas at 100 degrees C. this is more than 1200KJ of heat needed to be absorbed.
How long do you heat water to get 98.6 degrees?
depends on the amount of water
