How does energy change when you turn the kettle on?
The evaporation of water by boiling is the transfer of thermal energy (radiation or convection) to the molecules which form water vapor. The energy is the same, but it changes from kinetic to potential energy. As the water vapor gives up heat by conduction in the air, the water again condenses (dew, rain, ice, snow).
What happens in terms of the transfer of energy as a heat when you hold a snowball in your hands?
When you hold a snowball in your hands, the heat energy produced by your hands is transferred into the fusion of ice to water. Fusion is an endothermic reaction.
How does energy transfer by waves differ from energy transfer by a moving object?
In energy Transfer by waves, the energy moves through the the medium, for example the water, but isn't carrying the water with it. In energy transfer by a moving object the energy is traveling by means of an object. So, energy transfer by waves can be pictured as a person (the energy) swimming through water (the medium) and energy transfer through an object can be pictured as a person (the energy) riding a bicycle (the object) In the first case the energy itself is moving through a medium, where in the second case the energy is using its power to move by use of an object. Hope this helps you understand!
What transfer of energy from land or water to air by direct contact?
The transfer of energy from land and water to air by direct contact is called conduction.
Which form of energy is solar energy?
it a solar energy is wind,ice, or water
How do you perform energy transfers?
A simple way to illustrate energy transfer is to put an ice cube in a glass of water. The heat energy from the water will transfer to the ice cube until thermal equilibrium.
Which energy transfer occurs when ice cubes are placed in water that has a temperature of 45C?
it gained no energy. it melted. therefore is no longer an ice cube, & something that doesnt exist has no engery.
Where does thermal energy move to when you put an ice cube to hot soup?
Heat moves from the water that has higher temperature towards the ice cubes. This transfer of heat melts the ice cubes. Remember that heat travels from higher temperature body towards the one with the lower temperature. So thermal energy flows from the water on the glass towards the ice cubes.
Where do waves transfer energy?
they transfer energy through sound water and air.
Why does an ice cube melt faster in water than air?
One is the temperature of the water could be warmerSecondly when an ice cube is in water, conduction takes place. The kinetic energy of the water particles more time.moves to the ice causing it to melt. When in air radiation or convection must take place which will take
What energy transformations take place in a melting ice cube?
It requires energy to melt ice, converting it into water. This energy is recovered (returned to the environment) when the water freezes. Therefore, it is convenient to think of the water as storing this energy, while it is in the liquid state.
Which contains more heat 1 kg of water or ice at 0 c?
Both will have the same heat, as heat is the transfer of thermal energy, and both of them being H2O, their heats will be the same, meaning that they both transfer thermal energy at the same rate because they are the same chemical. The 1kg of water will have more thermal energy and usually will have a higher temperature, as the liquid phase indicates more thermal energy than solid ice.

What is hydraulic energy?
Hydraulic energy is an energy transfer from the water to waterwheels and mills.
What is the energy is stored by ice and water?
kinetic energy
