When heat travels, the particles jiggle and therefore bump into each other. This causes a 'chain reaction' if you will. Eventually, the particles will jiggle slower and slower. It takes a long time to heat up a lot of water because the particles constantly have to jiggle against each other with a lot of energy. Energy=time, that's why it takes longer. In a little bit of water, the energy doesn't have to travel as far, resulting in hotter:faster.
What else can I help you with?
Does it take more energy to heat cold water to 212 F than it does to change 212 F water to steam?
Yes, it takes more energy to heat cold water to 212°F because you need to increase the temperature of the water. Once the water reaches 212°F, it requires more energy to convert it to steam because you need to overcome the latent heat of vaporization to change its state from liquid to gas.
Does it take more heat to heat water or to boil water?
It takes more heat to boil water than to simply heat water. Unless the water is already at its boiling point.
How does the amount of water put into a kettle affect the time it takes to boil?
The more water you put into the kettle, the longer it will typically take to boil. This is because more water requires more energy to heat up to boiling temperature. Conversely, less water will heat up faster because there is less volume to heat.
Does it take less energy to heat hotter water than colder water?
Yes, as the molecules of the hot water are already in motion, they need less energy to speed up and transfer it whereas the molecules of cold water need far more energy so that they get into motion and then transfer energy.
How much energy does it take to melt ice?
Heat because Ice and water would thaw out and begin to heat up
Does water require energy?
If you take energy in the form of heat, from water it will freeze and so is not water any more.
Would it take more thermal energy to heat up a cold pan of water than a hot pan of water?
Yes
It would take more thermal energy to heat up a cold pan of water than a hot pan of water?
Yes
It would take more thermal energy to heat up what kind of pan of water than another?
A bigger pan would take more thermal energy than in a small pan
Which would take more energy to increase temperature by 5 degrees water or Aluminum?
It would take more energy to increase the temperature of water by 5 degrees than aluminum. This is because water has a higher specific heat capacity, meaning it requires more energy to raise its temperature compared to aluminum.
Does it take more energy to heat cold water to 212 F than it does to change 212 F water to steam?
Yes, it takes more energy to heat cold water to 212°F because you need to increase the temperature of the water. Once the water reaches 212°F, it requires more energy to convert it to steam because you need to overcome the latent heat of vaporization to change its state from liquid to gas.
Why does it take more time to warm up then cool down water?
When warming up water, heat energy is transferred from the heat source to the water molecules, causing them to gain kinetic energy and increase in temperature. This process takes time to distribute the heat evenly throughout the water. In contrast, when cooling down water, heat is removed from the water, causing the molecules to lose kinetic energy and decrease in temperature. This can happen more rapidly as the heat source is removed and the water cools down to reach equilibrium with its surroundings.
Why taking heat energy away cause water vapor to turn to liquid?
If you take away heat energy the particles move more slowly. This means the forces of attraction between them have more chance to pull them together.
Does it take more heat to heat water or to boil water?
It takes more heat to boil water than to simply heat water. Unless the water is already at its boiling point.
Why does water take so long to warm up?
The specific heat of water determines how much energy is needed to heat water.
Does water conduct heat away from your body faster compared to air does?
Ok, lets assume that a pool of water and the air are at the same temperature. There are a number of ways you can lose heat to the surroundings, however in this example the most important reason is: Conduction. This is due to direct contact with surrounding particles. As the Particles in you body vibrate with energy they collide with surrounding air or water particles. You will thus lose much more energy to water than to air as water is much better at conducting heat away from you. (There are many times more water particles to transfer the energy away). In terms of heat capacity, if water has a higher heat capacity then it will take more energy from your body to heat it up. Seeing as you body is warmer than the surrounding water, the water will take more of your thermal energy to reach thermal equilibrium with you.
How does the amount of water put into a kettle affect the time it takes to boil?
The more water you put into the kettle, the longer it will typically take to boil. This is because more water requires more energy to heat up to boiling temperature. Conversely, less water will heat up faster because there is less volume to heat.
