When heat is added to the water, the molecules move faster. When the water reaches the boiling point (100 Degree Celsius), the water molecules at the surface of the water would break apart with the other molecules and escape (evaporate). When they evaporate, the water molecules changes state and becomes water vapour.

Why is heat applied in Benedict's test and not alcohol emulsion test?
In Benedict's test, heat is applied to help facilitate the redox reaction between reducing sugars and the copper (II) ions in the Benedict's reagent, leading to the formation of a colored precipitate. In the alcohol emulsion test, the presence of lipids is indicated by the formation of a white turbidity or opaque layer when lipids are mixed with alcohol and water, and heat is not necessary for this observation.
When trees transpire releasing gaseous water into the atmosphere they can absorb heat from their environment and cool it down What property of water is responsible for this activity?
The high specific heat capacity of water is responsible for trees absorbing heat from their environment to cool it down when they transpire. Water's ability to absorb and release large amounts of heat helps regulate temperatures in the surrounding area.
Why is temperrature less of a limiting factor in water biomes than in land biomes?
Water has a higher heat capacity, meaning it can absorb and retain more heat than land. This helps buffer temperature changes in water biomes, making them more stable. Additionally, water's high heat conductivity allows for heat to be distributed more evenly throughout the water column, reducing temperature extremes.
Why do large bodies of water maintain a relatively constant temperature?
water has a higher specific heat, which is the amount of heat needed to raise a given mass of something by one degree, than does land. So water is harder to heat up( requires more energy) than land.
If friction generates heat why can't i stir a bucket of water to boiling point?
Excellent question, to answer this, you must understand that the bucket and stick are not an isolated system, and hence will continually lose heat to the environment (if it is greater in temperature than the environment). You are correct in saying the stirring the bucket of water will generate heat. The heat is minimal, and if the bucket and stick were somehow in a perfectly isolated system, you would eventually stir to its boiling point. However, since they are not an isolated system, the water will gain temperature until the temperature is greater than that of the environment, at which point the water will begin losing energy/heat into the environment. It is the rate of heat loss to the environment and rate of heat gain from the stirring that determine the final equilibrium temperature, since stirring generates heat at a very slow rate, once the water reaches the environmental temperature, the heat loss will approximately equal the heat gain. Therefore, unless you being to stir extremely fast (may be possible with a machine) and the rate of heat gain is large enough to bring the temperature of the water to boiling point despite the constant heat loss tot he environment, you will never stir a bucket of water into boiling.
What will happen to iron if heat is applied?
it melts
What might happen to water quality in a heat wave?
What might happen to water quality during a heat wave
Which item decreases as heat is applied?
Volume is increased so density is decreased.
What will happen if you heat the sugar without water?
Nothing will happen :))
Why does water heat up quickly if the heat is applied from the bottom?
Water heats up quickly when heat is applied from the bottom because hot air rises and creates circulation within the water, leading to more even distribution of heat. This process, known as convection, helps the water to heat up efficiently and quickly from the bottom up.
What would have to happen to make an ice cube melt?
Heat must have to be applied to the ice cube.
Do water evaporate when heat is applied?
Yes it does. Check in your science workbook.
What will happen to the powdered sulfur when heat was applied?
When heat is applied to powdered sulfur, it will melt and eventually vaporize. This process is called sublimation, where a solid substance bypasses the liquid phase and turns directly into a gas.
If there is less water will it get hotter quicker?
Yes, if the same amount of heat is applied.
Why balloon filled with water not pop when heat is applied?
When heat is applied to a balloon filled with water, the water absorbs some of the heat energy, preventing the balloon from reaching a temperature high enough to burst. The water inside the balloon also helps dissipate the heat more evenly, reducing the likelihood of a rapid increase in pressure that could cause the balloon to pop.
How water evaporate?
When heat is applied to water, the molecules excite and move faster, and change into a gaseous state.
Energetically what must be done or what must happen before water can boil?
Before water can boil, energy in the form of heat must be applied to the water to raise its temperature to the boiling point, which is 100°C (212°F) at sea level. As heat is applied, the water molecules absorb the energy and become more energetic, eventually reaching a point where the hydrogen bonds holding the water molecules together break, resulting in the water transitioning from a liquid to a gas state known as steam.
