Why Did water Temperature change?
for example :ice can change the temperature of water
When water boils and evaporates what 3 things change?
A phase change occur, energy is absorbed, water volume decrease.
Is photosynthesis a physical change?
No, photosynthesis is a chemical change by which water and carbon dioxide are converted into oxygen and carbohydrates.There is an energy transformation. Light energy is converted to chemical energy
What has to happen for water to change temperature?
the energy from the sun goes to the equator causing a temperature difference at the poles. Blowing cold wind over the water, and the suns energy on the water effects the temperature change in the water.
What is the amount of energy can change a solid phase to a liquid phase?
Every element has its own energy requirement to change a solid to liquid form. This energy , for water. is 80 calories (333 Joules) to turn a gram of ice to liquid water.
What a water able a hydroelectric dam have kinetic energy or potential energy?
The raised water, which stores the energy, has gravitational potential energy.While it is moving, the water has kinetic energy.
How can mechanical energy change into chemical energy?
when your moving water what does mechanical energy change to
What is the formula for water energy?
If you are talking about mechanical energy, you can use the formulae for gravitational potential energy (if the water is in a raised position), or for kinetic energy (if it is moving).If you are talking about heat energy, you can use the formula for heat energy.
How a change in energy can change into liquid water?
by boiling the water or putting it in the sun
What Machine joined to a generator to change energy from flowing water into energy?
A water turbine
Difference between a pysical change and a chemical change?
Chemical change changes the electrons of matter, a physical change does not. Water is water as ice, water and steam, this is a change of state but physically there is no change of water it is a change of the energy content of water.
Why Did water Temperature change?
for example :ice can change the temperature of water
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.
Energy that is absorbed by land and water is changed into?
some of the energy,however, is absorbed by the land and water and change into heat
When water boils and evaporates what 3 things change?
A phase change occur, energy is absorbed, water volume decrease.
What change of state and what energy changes occur when water freezes?
the state change is from liquid to solid and the energy change is cold energy to heat energy
What type of energy is required to change ice to water?
Heat
