If water temp changes 15 degrees C how much heat was gained by the water?
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 are the amount of heat transferred and the change 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.
Explain why you can feel the heat from a grill?
heat raises
How will the amount of thermal energy lost by hot water be related to the amount of thermal energy gained by cold water?
The energy lost by the hot water will be gained by the cold water until they both come to equal temperature. Then there will no longer be any heat transfer from hot to cold. I think the mathematical relationship is a natural log curve that asymptotically approaches the horizontal - meaning the cooling curve keeps getting less steep over time as the heat is exchanged
How much heat must be transferred to liquid water to change the waters temperature from 27 degrees Celsius to 32 degrees Celsius?
To change the temperature of water from 27ºC to 32ºC will depend on the mass of water that is present. Obviously, the more water, the more heat it will take. This can be calculated as follows:q = heat = mC∆T where m is the mass of water; C is sp. heat = 4.184 J/g/deg and ∆T is 5ºC (change in temp).
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.

When enough heat energy is gained by liquid water the liquid water can?
molecule
Explain why water is used in hot water bottle for fomentation?
bcoz water has high latent heat
Why the temperature of the water at bottom of water fall is different from temperature at the top?
Heat is lost to or gained from the air while falling.
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
What is a correct numerical set up for calculating the number of joules of heat gained by water?
(mass)(temperture difference)(4.18)
Explain the advantages of using oil instead of water in storage radiators?
Oil will retain the heat longer than water.
Explain why insulating a hot water tank reduces the energy you use?
Insulation keeps heat from escaping. So if you insulate a water heater, it holds heat better, and does not need to reheat the water as often.
Explain what happens when we suply heat and energy to water till it change its state What is this eat energy called?
When water has heat and energy it changes energy. The energy that it changes to is called thermal.
Explain why a bottle of milk keeps better when it stands in water in a porous pot in a draught?
Heat drawn from the milk when the water evaporates.
How much heat is absorbed when 500 g of water Cp equals 4184 Jg oC goes from 250 oC to 350 oC?
Heat gained by one object = Heat lost by the other. Does that help?
